Plugable USB Bluetooth Adapter: Solving HFP/HSP Profile Issues on Linux

It has come to our attention that there are some issues on certain Linux systems with regards to using Headset Profile and Hands-Free Profile with our USB Bluetooth Adapters.

The issue stems from a lack of support for these profiles on the Broadcom BCM20702 chipset found inside our device, unless a proprietary firmware file is loaded into it to enable this functionality.

The steps to install the firmware are as follows:Screenshot from 2014-06-23 17:34:49

  1. Open your favorite terminal
  2. Run the following command to download the firmware file:

    wget https://s3.amazonaws.com/plugable/bin/fw-0a5c_21e8.hcd

  3. Copy the firmware file to the /lib/firmware folder:

    sudo cp fw-0a5c_21e8.hcd /lib/firmware

  4. Reboot

That’s it! HFP and HSP profiles should now work without issue!

We have also heard of some reports that these steps can solve some issues with other profiles, like A2P, but have been unable to reproduce the issues.  It is possible that newer versions of BlueZ and the Linux kernel have fixed these issues, and that is why we are not seeing them any more.

Plugable Launching Kickstarter for the Pro8 Docking Station with Charging for the Dell Venue 8 Pro on Wednesday, June 25th

Update: June 25th – The Kickstarter is Live!


Our Dock Connected to a Dell Venue 8 Pro with a Monitor, Keyboard, Mouse, Ethernet Connection, & Headset Attached! All that with 2 USB ports to spare!

We released a demo video on YouTube last November showcasing the Dell Venue 8 Pro with our flagship UD-3900 USB 3.0 Dual Display Universal Docking station, essentially turning the tablet into a full desktop workstation. We received an extremely warm welcome from the Dell Venue 8 Pro user community and even caught the attention of Michael Dell (CEO, Dell) himself who retweeted our video. To this date we have over 150,000 views and almost 400 user comments.

Although this video showed the full capability of the tablet, it also highlighted a major flaw that could limit its uses: there is only one USB Micro B port that can only be used to either charge the tablet or to connect it with external USB devices. This seriously limits the Dell Venue 8 Pro’s capabilities as it cannot remain connected to a monitor, keyboard, and mouse during a full 8+ hour work day without running out of battery well before then. Consumers quickly realized this problem and the solution to this constraint quickly became an active topic of conversation on the comments on the YouTube video and in many tech forums. This Kickstarter is the culmination of our work to make that happen!

Some of our early prototypes

After months of development and multiple prototypes, we have created a product that allows full desktop replacement functionality and to charge at the same time. Furthermore, this docking station also works with the Lenovo Miix 2 which faces the same critical limitation as the Venue. Currently we are in the final phase of prototyping and are working with our manufacturing partner to perfect the docking station so that it can be brought to the market in mass.

Do  you know someone with a Dell Venue 8 Pro or Lenovo Miix 2 8″ Windows Tablet? Let them know about our Kickstarter! Even if you don’t and just want to support Plugable, please pledge just $1 and we pledge to keep you up to date on our progress with exclusive updates along the way. This will give you special access once the device goes on the market and a huge thank you from us! Every single dollar will help us reach our goal!

We are launching our Kickstarter on Wednesday, June 25th 10AM PDT for this exciting new product and we need your help! If you are interested in supporting this project then you can sign up for email notifications here at http://plugable.com/kickstarter

Plugable’s new USB “On The Go” MicroSD reader

A compact solution to access MicroSD cards from both standard and micro ports. Plugable’s new USB2-OTGTF is designed to make life easier for digital denizens by enabling access to a MicroSD card from as many devices as possible.

Just insert your microSD card as shown here, and connect to an available USB 2.0 “A” or “MicroB” port.
sdinsert_animated

Many, if not most, portable devices today support inserting a MicroSDHC (up to 32GB) card directly, via the OTGTF’s USB 2.0 A, or USB 2.0 “Micro B” connectors.

The USB-OTGTF’s compact design and flexible make it a great solution if you’ve ever:

  • Been frustrated waiting for a long sync to your device to complete
  • Wanted a way to take more of your media collection with you
  • Struggled with how to get a photo, long complex password, or some other data from one device to another.

3-plugged to phone
If you have an Android device without a MicroSD slot but need a way to increase your device’s storage capacity, check our post on OTG Host and USB mass storage support for Android. Regardless of OS, up to 32GB additional storage is available using this adapter — MicroSDXC cards above 32 GB are *not* supported.

We’ve even made the packaging easy to open — no blister pack or knife here — just pop open the corner of the plastic, like a tupperware, as shown below:

“Many devices today…” So what doesn’t work?

Customers are often surprised when they find a USB port on their device won’t work with a certain device– especially so when the device is a simple flash drive or card reader. Apple’s popular iOS, and any iPads, iPhones, or iPods simply don’t support USB storage devices, and simply won’t work with this adapter.

Android device support will be hit-or-miss on devices running Android 4.x.x. Older Android 2.x and 3.x devices are unlikely to support USB mass storage, although a few devices may work. This is because not every Android device supports the two USB standard device classes needed:

  1. Support for USB “OTG” host mode
  2. Support for USB Mass Storage class devices

Each Android device maker gets to customize the exact version of Android they distribute, so some devices will have support for accessing data on USB storage devices, and others will not. Some manufacturers have chosen not to support USB storage. When that happens, there are a few options for adding this support via applications, or, for very advanced or adventurous users, to install a version of android that does support USB storage on their device.

The good news is that many popular Android devices do support USB storage devices. When a device fully supports USB mass storage, it will pop up a notification when a storage device is attached– typically noting the “mount point” where you can navigate using your file manager of choice. If your device doesn’t “just work” with a USB storage device, read our post on adding USB OTG and MicroSD support to Android devices.

“Just Works” with all Windows devices

And, of course, if you have a Windows Tablet with either a standard “A” or “Micro-B” OTG port (like the Dell Venue 8 Pro), you know it will always work as support for USB storage devices is built into all versions of Windows (since XP).
