What BadUSB Is and Isn’t

The BadUSB exploit is an idea and working proof of concept which takes advantage of the fact that some USB devices have firmware, and on some of those devices the firmware can be updated.

BadUSB has exploded onto the press in the last few days with articles like Wired – The Unpatchable Malware That Infects USBs Is Now on the Loose, CNBC – Why USB malware just became a big problem , The Verge – This published hack could be the beginning of the end for USB.

2014-10-06-Phison-Flash-Storage-ControllerThis first wave of articles have a few problems, as you might guess. As a former Development Manager of the USB team at Microsoft and the founder of a USB device maker (Plugable Technologies), I hope to fill in a few more of the pieces.

First off, this is a real family of security issues. Anywhere there’s running code, there’s opportunity for exploit. In the Internet of Things era, there is code running nearly everywhere. As electronics shrink, things we think of as “devices” are really computers. To deal with an evolving world, we often want these little devices to be software fixable and upgradable. This creates risks that need to be actively mitigated.

To hack a computer with a USB device, at least 2 things have to be true:

  1. The USB device being infected needs to have firmware, that firmware needs to be software upgradable, and that upgrade mechanism needs to be insecure. That is true of some USB devices but not others.
  2. If a USB device is vulnerable, the virus has to be designed for particular USB controller(s) in that device. The method of flashing firmware on the device and the instruction set is controller specific. The BadUSB code out now is specific to one USB flash controller (Phison) and won’t affect other USB devices. It is not a universal attack.

Whether #1 and #2 are true depends on the particular device. Take our Plugable USB product line as an example: none are exploitable with the BadUSB code as it stands right now because we don’t use the Phison controller. However, some would be vulnerable if specific attacks were targeted at the specific controllers in the devices.

main_512For example, the Termius Technology Chipset used in all of our Plugable-brand USB 2.0 hubs is a fixed-function hardware ASIC without executable or updatable firmware. These USB devices are not vulnerable to BadUSB-style attacks of any kind.

On the other side, our USB 3.0 SATA drive docks use the ASMedia 1051E and 1053E chipsets, which have an 8-bit microcontroller. It is firmware upgradable. So while the recently released BadUSB code will not infect these docks, in theory they could be targeted in the future with a similar effort to that which went into BadUSB.

An interesting 3rd example is our Plugable USB 3.0 Tablet / Laptop Docking Stations and Graphics Adapters. These use DisplayLink DL-3×00 and DL-5×00 chipsets. They make use of firmware. That firmware is software upgradable. However, DisplayLink has implemented on-chip authentication, encryption, and firmware validation which makes it quite difficult for any 3rd party to successfully update firmware. To date, no 3rd party has successfully been able to crack this and talk to the DisplayLink chip. That is one of the reasons why these products work only with Windows and Mac where DisplayLink provides drivers themselves. No software-based security is invulnerable. But it can be a strong mitigation.

You can find out which USB controllers are used in our products on the product pages at Plugable and on Newegg or Amazon listings, etc. We do that because chipset is the best way to dig into compatibility details, but it’s also the best way to research what security features the chips have. We’ll be working to expand on our security information and features over time.

Hopefully some of this detail helps create a fuller picture of what BadUSB is and isn’t. You can also get a lot of great detail from Brandon Wilson and Adam Caudill’s video of how BadUSB was created. If you have any questions, we’re happy to share what we know, just comment below.

USB Stock Chargers, Dedicated Multi-Port Chargers, or Charge & Sync Hubs. What’s Best for Me?

In today’s world of mass portable devices with USB connectivity, charging should be as simple as plug and play. Unfortunately, it’s not that easy. Take me for example. On my desk I’ve got a Google Nexus 5, Dell Venue 8 Pro, Apple iPhone 4, and several generations of iPad. Each one came with a completely different power adapter for charging! My Nexus will charge off of almost anything, my Dell Venue 8 Pro is quite picky, but Apple might be the most confusing of them all.

The reason is USB charging has not been well standardized until recently. Apple has been charging devices via USB with special signaling since the first USB connected iPod. Devices determine whether and how fast to charge, and make that decision based on different non-standard methods to recognize “their charger.”

Take for example the following charging signals commonly seen today:

  • Apple 2.4A (12W)
    (iPad Air / iPad Mini, likely any subsequent iPad releases)
  • Apple 2.1A (10.5W)
    (original iPad through iPad Retina)
  • Apple 1A (5W)
    (first seen with the iPod all the way back in 2002, commonly found with all iPhones including the newly released iPhone 6/6 Plus)
  • Dedicated Charging Port, DCP (wattage varies per device)
    (often referred to as the Android charging signal, common for almost all non-Apple devices)
  • Samsung 2.4A (12W)
    (usually seen with Samsung tablets, potentially some phones)
  • USB-IF BC1.2 CDP 1.5A (7.5W)
    (the official USB charging standard, it’s not well adopted yet, but more devices are becoming compliant)

What exactly does all of this mean?

In short, taking my Dell Venue 8 Pro as an example, I can’t plug it into just any USB charger and expect it to charge, it works on Android and Apple 1A signals but won’t charge on any of the others. Or if we take my iPad Retina and plug it into my iPhone 4 charger, it’s going to charge at an overly slow rate.

Because of scenarios like these, most users have a preconceived notion that they must use the stock charger that came with their device. Sometimes with the fear that if they do not, their device won’t charge, or worse, could actually be harmed.

Fortunately this isn’t the case. In fact, most devices on the market can actually charge from the Apple 1A signal as it has unofficially been adopted as the universal USB charging standard; mainly because it’s been around for so long. Also a device will only pull as much power as it needs, so using a more powerful charger may actually help your device charge faster. The newly released iPhone 6 and 6 Plus ship with the standard Apple 1A charger, but will charge much faster on the Apple 2.1/2.4A chargers or another charger that the iPhone 6 recognizes.

Many consumers don’t realize they can downsize their growing pile of stock chargers for a more convenient multi-port charger that can charge almost every USB charging device in their home simultaneously from just one AC wall outlet. Take our flagship multi-port charger, the Plugable USB-C5T (temporarily out of stock 10/3/2014). It has 5 USB charging ports with enough power (7.2A, 36W) to charge two iPads and three iPhones concurrently (or three iPads and one iPhone, etc) at their maximum charging rates.

Click to enlarge.

The Plugable USB-C5T, bringing order to chaos.

Three of the C5T’s USB ports simulate the standard Apple 1A signal which will charge most devices, including my picky Dell Venue 8 Pro, but where the C5T really shines is with the two outer ports which are equipped with a smart charging chipset made by the folks at Genesys Logic. The GL888F chipset can simulate almost all of the aforementioned charging signals (sans Apple 2.4A) and will intelligently select the best one for your device. This is great because if your device happens to not be compatible with the standard Apple 1A signal, chances are it will charge off of the smart ports.

Great. Sign me up!

Not quite yet, but we’re almost done. Have you ever tried to charge your device from your computer only to be let down by slow charging or no charging at all? If so, you’re not alone, it happens to the best of us. When you connect a phone or tablet to a computer, the device wants to put itself into a mode where data can be synced. Often syncing while charging either isn’t possible or is extremely slow, only drawing around 0.5A from the host computer’s USB port. This behavior is also expected on all USB hubs unless they are BC1.2 compliant. The BC1.2 charging signal, CDP (charging downstream port), is compatible with all current Apple Lightning Cable devices like the iPad Retina / iPhone 5 (and newer) and many new Android and Windows Mobile devices are moving this direction as well.

Our flagship 7-port USB 2.0 hub, the Plugable USB2-HUB7BC, is BC1.2 compliant and devices can charge at up to 1.5A while syncing data. The HUB7BC can also act as stand alone dedicated charger when the computer is turned off or not connected. To many this is the proverbial “holy grail” of USB charging despite slightly slower charging rates (1.5A) compared to a dedicated smart charger like our GL888F (up to 2.4A) equipped USB-C5T due to the added convenience of charge and sync.

In a time where USB charge and sync functionality can be unnecessarily complicated, we work hard to deliver simplicity to the equation. With charge and sync being available on nearly any BC 1.2 compatible device, which is most mobile devices produced in the last few years, why would you want to haul around an individual charger for each device?

New DisplayLink Windows Driver Version 7.7 Leaves XP Behind

photo_power_searcherDisplayLink has released their new Windows driver version 7.7 M0. For most users, we’re recommending they stay on DisplayLink’s mature 7.6 M2 driver series for the time being, but this release does improve performance especially for 4K Ultra HD (up to 3840×2160) USB multi-monitor graphics adapters like the Plugable UGA-4KDP.

This release is also the first that is Windows Vista or later only. Windows XP users will need to stay on the Windows 7.6 driver series (or earlier). Windows’ graphics driver architecture was very different in Windows XP, causing DisplayLink’s driver to be “two drivers in one”. Dropping XP support in 7.7 allows DisplayLink to focus on and optimize for newer Windows versions. Note that for systems automatically downloading from Windows Update, the correct version will automatically be downloaded for you.

UGA-3000_In use illustrationWe’ve been testing this release since the betas, and had seen stable results with the betas. With the final 7.7 M0 release, however, we’ve seen problems during install and with missing cursors after install. Because the performance differences are most noticeable in modes above 1920×1080, and the previous driver version 7.6 M2 has proven most stable, we’re only going to point users of our 4K adapters immediately to this new driver. For sub-4K adapters, 7.6 M2 is well proven — and of course is essential for XP.

Detailed Release Notes

DisplayLink Software Release R7.7 M0 warnings: Some users have reported mouse cursor problems and install problems, requiring a revert to 7.6 M2. That release is well proven.

DisplayLink Software Release R7.7 M0 delivers the following improvements:

- Improved full screen video frame rate and image quality on high resolution screens
- Lower mouse cursor latency on desktop applications
- New embedded firmware upgrade mechanism improving first connect user experience. Visible from future releases.
- Early support for Intel Broadwell platform

Fixed issues since R7.6 M2 (7.6.56275.0)

Monitor EDID was incorrectly interpreted, if the monitor id contained an underscore (_). (17606)

Audio output might not switch to default after disconnecting headphones from DisplayLink device in hibernation (S4). (17401)

On some laptops, the video performance can decrease on DisplayLink screens when a proprietary docking station and a DisplayLink docking station are connected at the same time and the user logs on and off. (16915)

Some platforms running Vista x64 can stop responding after installing DisplayLink Ethernet driver. (17384)

DisplayPort++ to DVI adapters can display incorrect available mode list. (17427)

Occasionally a DisplayLink monitor could be blank after resuming from power saving mode. (17554)

Ethernet UDP performance might drop when playing video and audio over a DisplayLink device. (17579)

Intermittent screen corruption visible when a DisplayLink monitor duplicates a touch screen display in Basic mode on Windows 7 (17782)

Wake on LAN sometimes doesn’t work when DisplayLink device is connected at USB 3.0. This is a regression introduced in 7.6 M2. (17865)

Video and/or Ethernet not available after power state changes on some platforms. Ethernet could show a Yellow “!”, with Error Code 43, in device manager (17896, 17047)

If multiple DL-5xxx or DL-3xxx devices are connected, one device can fail USB enumeration resuming from S4 when connected to USB 2.0 on Windows 7. (17835)

Removed compatibility check which prevented installation if a 3rd party USB graphics solution was connected. Now installation will only be blocked if 3rd party USB graphics drivers are found to be installed. (17763)

Does OS X 10.9 Mavericks log you out of your session?

We do not recommend USB graphics solutions on OS X 10.9 Mavericks, because of compatibility breaks in OS X after 10.8.5. This unfortunately, has yet to be fixed. But it does work for some cases on 10.9.x, and we have had some die hard customers (including myself) using it daily. But lately there has been a strange and frustrating new problem. It seemed like the operating system would suddenly kick the user out of the session. All the work was lost, and there you were, sitting in front of the log-in screen scratching your head, wondering what happened.

This is a manifestation of the window server crashing which in the past would have all displays repeatedly go black/blank while the window server restarts but would still deem the system unusable.

After digging on various forums for answers why the window server would crash on Mavericks, a suggestion was made to disable certain animations. This forum post was of great help and it turns out if you disable “opening and closing windows and popovers” you severely limit the chances of your window server crashing while using DisplayLink products. To disable this feature, do the following:

  1. Open the terminal
  2. Run the following command:

    defaults write -g NSAutomaticWindowAnimationsEnabled -bool false

  3. Reboot

And that’s it. This is what it took to eliminate the windows server from crashing for our customers and myself. If you still experience crashes like these after running this command you can go down the list of the forum post and disable other features of animations such as “smooth scrolling”, “showing and hiding sheets, resizing preference windows, zooming windows” and “opening and closing Quick Look windows”.

Plugable Launches Small, Durable USB to Audio Adapter for Windows, Mac, Linux, and Chromebook Systems

The new Plugable USB Audio Adapter is a compact, effortless solution for adding an external audio interface to nearly any computer or tablet. The adapter has separate standard 3.5mm receptacles for stereo headphones and microphones. It lets you easily USB enable your favorite analog headset or headphones, so you don’t need to compromise to get USB connectivity back to your PC.

This can be used to bypass or replace a faulty sound card or audio port. It can be left connected to a USB hub or docking station to add convenient, easy-to-reach audio jacks — saving stress on the audio ports on your computer. The adapter body is lightweight and durable with its black anodized metal body.

The adapter is compatible with Windows, Linux, Mac OS X and Chromebook systems with a free full-sized USB port. No drivers are necessary as the adapter’s C-Media CM108 chip exposes the standard and widely supported USB Audio class.

Just plug in the adapter, select it as your default output and input device for instant audio playback. Note that most operating systems support multiple audio outputs, but only allow a single one to be enabled at a time. So this manual step of selecting the right audio output from the operating system’s built-in audio control panel is essential.

This audio adapter really shines with custom Linux development boards like the Raspberry Pi, Beaglebone Black, and other unique scenarios such as a “Hackintosh” setup where the on-board audio devices don’t have Mac drivers.

Plugable UGA-4KDP

New Adapter from Plugable Technologies Enables 4K Ultra HD Monitors up to 3840×2160 on Nearly Any USB 3.0 Capable Windows 7 and Higher System

Ultra HD 4K monitors with resolutions up to 3840×2160 are starting to move into the mainstream. Many Windows-based tablets and laptops shipped in recent years don’t yet support this new generation of displays, and certainly don’t support connecting more than one of them to a Windows PC.

We’re excited to announce the Plugable UGA-4KDP USB 3.0 Graphics Adapter. It’s the first widely available solution for connecting one or more 4K DisplayPort-based monitors to any Windows 7 or later PC with available USB 3.0 ports. Using one adapter per monitor, you can connect 6 or more huge monitors. The adapter is backwards compatible with USB 2.0, so older machines will work — but for most scenarios USB 3.0 is a must for performance reasons.

The Ultra HD 4K generation of monitors available today support either DisplayPort or HDMI inputs. This adapter outputs DisplayPort signals, enabling connection without any additional adapters. Output to HDMI-only monitors is still possible, but requires an active DisplayPort to HDMI adapter (not included) which supports these higher resolutions.

The DisplayLink DL-5500 chipset at the heart of this adapter is a virtual graphics device. It uses the computer’s own CPU and GPU for rendering pixels, then compresses and sends just the pixels that change over the USB bus. Actual display to the monitor is then refreshed from memory on the device at 60Hz for all modes up to 3840×2160, and 30 Hz at that highest mode.

This is a great solution for web and application use, but is not recommended for 3D gaming or motion video.

Have any questions at all? Comment below or email support@plugable.com – we’d be happy to help! We’re excited to help bring 4K to the PC masses – thanks for going out of your way for Plugable products!

USB OTG Checker Success

Adding MicroSD and USB Storage support to Android Devices

While MicroSD card support was once very common for Android devices, most “flagship” devices today don’t include this. Many among the current batch of top-end devices– including the HTC One, Nexus 5, and Motorola’s X and G models lack MicroSD support. If you’re not comfortable with using cloud backup services for your device, our Plugable USB2-OTGTF can enable quick, on-the-go backup of photos or other content normally stored only on a device’s internal storage.

If you have an Android device lacking a built-in MicroSD card, have heart- the USB2-OTGTF and a couple of applications may help. If you’re a technical user who has a rooted device, your chances are better, however some very popular devices have applications enabling basic support for even novice users. For example, although Google’s Nexus 5 doesn’t have MicroSD support,  adding it is relatively easy. Even for users without root access simply installing a couple of applications can enable access to a USB storage device like Plugable’s new USB2-OTGTF or basic devices like keyboards, mice, or other USB storage devices with low power demands.

To determine if your device supports USB Mass storage, first check if your device supports USB OTG mode. If it does, you may still need to install a second application to mount a storage device, and possibly a file manager if your device doesn’t already have one. To clarify, below are the features required for accessing files on a USB storage device on Android.

    1. Support for USB “OTG” host mode

USB OTG Checker SuccessThis is the level where the device “sees” that USB devices like keyboards, mice, or storage devices are attached. You can quickly check if your phone supports USB OTG mode using USB OTG Checker.

For USB OTG checker, just launch the app and choose the option to “Check Device OS on USB OTG” and then press the check button. If your device supports USB OTG devices, you’ll see this message.

    1. Support for USB Mass Storage class devices

This is the level where a USB storage device is “mounted” to a location in the file system. Access to whatever file system is located on the USB device is either provided via OS-level drivers, or, if the app has root access, it can potentially add drivers for additional formats.

Disk Formats and accessing your files

The several USB OTG apps for Android include various levels of support for different disk formats. Recent Android versions typically support FAT and EXT3/4 out of the box, and may support read-only NTFS mode on some devices. NTFS write, HFS+, or exFAT will require other adding driver support for these additional formats, and may not be supported by all applications.

Once your device is mounted and formatted with a supported disk partition, to access files on the card, use your file manager of choice. Many android devices include one by default, however if your device doesn’t include one many are available on the Google Play store. ES file manager and Astro are popular, but many other good options exist.

Experimenting with different USB OTG applications for your particular device and format needs may be necessary, and your mileage is likely to vary on different devices. For most users, using the FAT format to do any transfer of files from an Android device is recommended since NTFS write and exFAT support are limited. For users needing to access files over 4GB from an Android device, read-only NTFS is the option most likely to be supported out-of-box.

Read on to find out how we’re able to access up to 32 GB of data on a FAT32/exFAT/NTFS formatted MicroSD card on the Nexus 5 (thanks to support for these file formats in the StickMount application) with the USB2-OTGTF.

Example Usage Scenario: Nexus 5

On our example Nexus 5 with root access on stock Android 4.4.2, using StickMount (free to try) is easy, and enables access to FAT, exFAT, and NTFS formatted storage, even when all three exist on the same storage device. The Nexus 5 supports USB OTG Host mode without any extra apps or work, as confirmed by USB Host Diagnostics.

For non-rooted devices, OTG Disk Explorer Lite supports FAT32 storage only, and is free. For only $2.49, the Nexus USB OTG File Manager adds NTFS read-only support.

For rooted devices, StickMount offers read/write access to FAT formatted volumes, and read access to NTFS volumes. On the Nexus 5, FAT and exFAT read and write seem to work automatically after installing StickMount– at least if BusyBox is installed. NTFS works in read-only mode, and seems to work in write mode after installing the NTFS3G driver– although some applications still try and use the in-box read-only NTFS driver and will fail when trying to write to the device.

We used ES file manager in our tests, but Astro, OI and other great options are also available.

Other Devices and Troubleshooting

With USB Host diagnostics, you need to have a USB OTG adapter and a regular USB device, or a USB OTG device physically handy. While USB OTG checker is a great option for finding quickly if a device supports USB OTG host mode, for troubleshooting we recommend USB Host Diagnostics. After launching the app, connect an OTG device and follow the prompts to find out what issues your device is having.

A working Nexus 5 shows support for everything but the Rooted API, so any failures indicate a layer to double-check. To begin, download USB Host Diagnostics, launch the app, and follow the instructions. After completion, you’ll see a report as shown in the screenshot below. USB Host Mode Supported

Older Android devices may not have applications to enable USB Mass Storage support available, and that an application which works well on one device may not work as well on all others. Searching around for the best OTG storage applications for your particular device is recommended as a first step if you run into trouble. If you can only find OTG Storage applications for your device that require root access, it is likely that your device doesn’t support OTG host mode or a driver for a certain disk format.

In these cases the OTG mounting application has to install additional components to enable host mode– which requires root access. The very popular USB OTG Helper application’s developer maintains a list of devices known to work, or not work with USB OTG Helper.

When All Else Fails

In extreme cases when no application support for OTG storage devices is available, installing a 3rd party ROM like CyanogenMod (confirmed to support USB mass storage in both 10.4 and 11 builds on multiple devices) is a last resort. While 3rd party “ROMS” may boast newer Android versions and more features than those supported by the device’s manufacturers’ installing one will typically void the manufacturer’s warranty, and is likely to introduce it’s own unique issues.

Flashing a new ROM can be a frustrating experience for even for the most patient and advanced users, so proceed with extreme caution if you do decide to try replacing your “stock” Android build with something supported only by the good-will of the Android enthusiast community at large. Proceed with caution, at your own risk, and only if you can afford to lose access to the device you are trying to update if things don’t go as expected.

Plugable Tech Tips: How to Partition and Format a New Hard Drive (or SSD)

HDDs OMG

As we all progress further into the digital age, our need for additional storage space keeps growing. Digital photos, music, and movies take up large amounts of space, and adding an external hard drive to store additional media or for backup purposes is an ever-popular PC upgrade. While some tout the benefits of cloud-based storage, adding local storage capacity has many benefits including substantially better speeds as well as being vastly more secure. This introductory installment of Plugable Tech Tips will guide you through the necessary steps of setting up your new drive for use.

This guide outlines the process in Windows 8/8.1, though the steps are nearly identical for Windows XP, Vista, and 7. Each step covers a bit of explanation and context. If the “why” aspect of the process is not of interest, look for the bold text in the post which covers just the basic necessary steps.

This article also proceeds with the assumption that you’re using one of our Plugable hard drive docks (good choice!) such as the U3 or the UASP1. However, the instructions are the same if you’re using a non-Plugable dock.

Why do I need to do this? Don’t hard drives already come formatted for me?

Before a new hard drive can be used, it must be initialized, partitioned, and formatted. Pre-assembled external drives and enclosures from Western Digital, Seagate, and others generally come pre-formatted for Windows or Mac. These solutions are not without their drawbacks, however. Aside from often being more expensive than a DIY external drive, the hard drives inside these enclosures are also often accessed in a proprietary way. This means that if the enclosure itself ever fails, the data on the drive inside it may not be accessible without expensive data recovery services.

When you purchase a “bare” (also known as an “OEM”) hard drive, it does not come pre-formatted. The reason for this is that there are various operating systems in use, and they all have their own types of formatting which are often times incompatible with the formatting used in other operating systems.

Are there any precautions to take before proceeding?

Before covering the steps necessary to initialize and format the drive, a brief word of caution. Initializing and formatting a hard drive will erase *all* information on that drive. In the case of a new drive, that’s not a matter for concern – it doesn’t have anything on it to worry about. However, if there are already existing drives in use on the system, it’s absolutely critical to make sure that close attention is paid so that the wrong drive isn’t erased. If you have multiple external hard drives connected, we recommend disconnecting them prior to initializing your new drive, just as a precaution.

Okay, let’s get started!

  1. Insert the hard drive into the USB enclosure. Connect the power cable to your enclosure, and attach the USB cable between your enclosure and your PC. Use the power button or rocker switch to turn on the dock.
  2. Now we’ll want to head to Disk Management. In Windows 8.1, the most straightforward way to get there is to right-click on the “Start” button (aka the Windows logo where the Start button used to be) and select “Disk Management”. (For Windows XP, Vista, and 7, Disk Management can be accessed by right-clicking on “Computer”, selecting “Manage”, then opening Disk Management in the left side of the Computer Management window that opens.)

  3. 1

  4. When you open Disk Management, it should automatically detect a new, non-initialized drive and display a pop-up window asking if you’d like to initialize the drive. Again, please be sure that the drive in question contains no existing data before proceeding!There will be two options for how to initialize the drive, MBR or GPT. MBR is the older legacy method of initializing drives, and is only necessary if the drive will need to be accessed on a Windows XP system (XP is incompatible with GPT). GPT *must* be selected for drives over 2TB in size. If MBR is selected on a drive larger than 2TB, you will only be able to access the first 2TB of the drive, regardless of what the drive’s capacity is. GPT disks should be accessible on Windows systems running Vista and later.

  5. 2_Disk_Init

    (If you’re interested in much, much more information about MBR vs. GPT, Microsoft has a very thorough post here: http://msdn.microsoft.com/en-us/library/windows/hardware/dn640535%28v=vs.85%29.aspx )

  6. Once you’ve made your selection and clicked on “OK” to initialize the drive, it’s time to partition and format. If desired, multiple partitions can be created, but this guide assumes that, like most people, you want the entire drive to be accessed through a single drive letter/partition.Each Disk that Windows recognizes is given a number and has a horizontal bar representing the space of the disk any any partitions that exist. Since we’re working with a drive that contains no data, it should be listed as “Unallocated” space. It’s also a good idea to check that the drive size is what you’d expect it to be. In the following example, we’re working with a 1TB drive, which Windows reports as 931.39 GB.

    3_Unallocated_1

    Right-click the unallocated space, and select “New Simple Volume”.

    4_SimpleVol

    You will be guided through a series of steps. For the vast majority of users, just accepting the defaults and clicking “Next” will be fine. The two items that you may wish to change are the “Assign the following drive letter” if you’d like your drive to have a specific letter assigned, and the “Volume label”, which will be the name you see associated with the drive letter in Windows File Explorer.

    steps

After these few quick steps, you’re all done and your new drive should be ready for use!

Mac OS X iPad Charging Error with iPads on BC 1.2 Charging Hubs

With the addition of new BC 1.2 (USB-IF Battery Charging Standard) compatible charging hubs to our product line we wanted to shed some light on a bug we have discovered for Mac users. When using any of the following products an OS X pop-up error message may occur that claims the users iPad is not charging through the hub:

macos_bc12_charging_error

Click to enlarge.

When checking charging status on the iPad itself, it shows that it is indeed charging and can also be confirmed in iTunes. To be completely sure, we test charging rates using a multimeter and confirmed the iPad was charging at the standard 1.5 amp BC 1.2 CDP (Charging Downstream Port) charge rate.

Plugable Announces Desk Clamping 6 Outlet Surge Protector with 2 USB Charging Ports

mainAround the office, we’re constantly needing to connect and charge new devices. It’s always a struggle to find a power outlet with enough open spots, and getting many larger plugs to fit, and of course the battle in the dark to actually find an outlet while you’re crawling on the floor under your desk. Plugable’s new desk clamping surge protector helps avoid all of these frustrations thanks to the unique desk clamping design, the 2 oversized “wall-wart” capable outlets, and the 2-port 10.5W (2.1A shared) USB charger built in to eliminate the need for separate USB chargers.

No longer will you need to climb under your desk, searching in the dark to find an open outlet. Instead, just plug it in at arms height!

With up to 2100 joule protection, the PS6-USB2DC offers better surge suppression than many other bargain surge protectors. Joules are a measure of how large a surge is, so a higher joule rating means a protector is able to suppress a larger surge — so the higher the joule rating, the better protection a suppressor offers.

USB Charging
Battery charging over USB has become a standard practice but the actual charging behavior of different devices is often unpredictable and sometimes disappointing. The devices themselves decide how much current to draw and manufacturers haven’t settled on a single standard. We’ve been working to test our products with as many different devices as possible and publish the results so it’s easy to determine the charging behavior to expect from your device on each of our USB products. These are the results for the devices we’ve tested on this device so far.

The "MAX of mA with Host On" is a bit confusing at first glance. The easiest way to understand this is that these values are the maximum reported charging rate (mA) when connected to a computer (host) that is powered on. The "Max of mA with Host Off" is simply the opposite, it is the charging rate (mA) when there is no connected computer (host) or if the computer is turned off.

Some entries in the charging sheet contain blank spaces for the syncing capabilities, that is because we have not had a chance to test that device yet for syncing.

Note that some devices, may charge only at slow "trickle charge" rates, and not indicate they are charging. These are shown as a 0 charge rate.

Not satisfied with how your devices charge?
Take a look at the USB-MC1 charging adapter. This charging adapter let's you turn any USB port on a powered USB hub or computer into a 1A charging port. The only limitations is that the AC adapter of the powered USB hub needs to be rated for at least 1A for each USB charging adapter. For instance, you won't be able to turn your 10 Port USB 2.0 Hub into a 10 port charging station as the USB hub comes with a 2.5A AC adapter. This means that you can charge at most 2 devices using the USB Charging Adapters, because each adapter will consume 1A leaving .5A for any other devices on the hub.

Let us know if you have any questions at all about our new product. And thanks for going out of your way for Plugable products!
