Plugable launches Aluminum 7 Port USB 3.0 Hub

Customers interested in a USB 3.0 hub with timeless beauty and performance to match need look no further than the Plugable USB3-HUB7A!


A brushed aluminum finish with white accents complements Macs and MacBooks perfectly, and will match popular aluminum or silver ultra-books. Also a great companion device for the Surface Pro or Surface RT, Lenovo Yoga 13, or other tablets featuring only a single USB port, this powered hub enables one-wire connection of peripherals like keyboards, mice, printers, or even USB graphics devices (on supported operating systems, Windows RT NOT included).


USB3-HUB7A units have been updated with firmware version 858x, tested to work well with both Windows 8, and OS X 10.8.x, as well as older systems running Windows 7, Windows Vista, Windows XP, and OS X systems with both USB 3.0 and USB 2.0. Older USB 1.1 devices connected to USB 2.0 systems via the hub are also supported.


For desktop PCs where USB 3.0 ports may be hard to reach, the HUB7A’s design with top-facing angled ports can make connecting devices easier. The extra ports on a USB hub can also help avoid damaging built-in ports when frequently swapping devices. The built-in power button on the hub also makes for a convenient way to quickly disable the hub’s individual per-port LED’s, and all attached devices with the press of a single button.


With the included 5 volt 4 amp power supply, more than enough power to operate several power-hungry devices is available. In most real world scenarios 3-4 devices with their own power supplies like printers, scanners, self-powered external hard drives, or low-power devices like keyboards and mice mean that the USB3-HUB7A’s per-port power availability of ~570mA is more than sufficient for up to 7 connected devices. The included power supply will support up to 4 power hungry devices requiring USB 3.0′s full 900mA in addition to several lower-power USB 2.0/1.1 devices or self-powered devices like printers and scanners. Even among USB 3.0 devices, it is unusual for a device to require the full 900mA.

One exception of note is the Apple “SuperDrive” which requires a direct connection to a supported Mac. From

The SuperDrive is designed exclusively for use with MacBook Air, MacBook Pro, and Mac mini’s that do not have a built-in optical drive. The SuperDrive must be directly plugged into the computer’s USB port, and cannot be used if connected to a USB hub.”

To be clear, in unusual cases where USB 3.0′s full 900mA per port is required, a maximum of 4 devices are supported. Standalone device charging is also NOT a feature of this hub: customers seeking a hub with charging capabilities should consider the USB2-HUB4BC.

Troubleshooting the USB3-HUB-81×7 USB 3.0 7 port Hub

Most customers purchasing our black 7 port USB 3.0 hub, the USB3-HUB7-81X, shouldn’t have any problems.

In case of issues, the troubleshooting steps below are likely to provide a quick resolution. If you run into questions or find that these steps aren’t helping, please comment on this post or send an email to and we’ll be happy to help! Attaching the output from our support tool, PlugDebug, generated while the hub is connected and powered up will also help us recommend the right steps. Instructions to download and use PlugDebug are here:

Following these steps in order is recommended:

  1. Verify that the hub is operating in “Self-Powered” mode.
  2. Update Host PC USB 3.0 Controller software.
  3. Update hub firmware.
  4. Update/Install device-specific drivers or firmware.

Ensure the hub operates in “Self-Powered” Mode

When connecting the hub to the PC, it is important to connect the AC power supply to the hub 1st, and then connect USB from the hub to the host PC. If the hub is connected to the PC before power is, devices may not be recognized properly. To ensure that the hub is operating in self powered mode:

  1. Verify that the Green power LED on the AC power supply or “power brick” is solid, with no flashing or blinking, and that the connection to the hub is secure.
  2. After verifying normal operation of the power supply, unplug the USB connection from the back of the hub, wait 10 seconds, and reconnect it.
  3. Test whether devices work normally first in ports 5-7, and then in ports 1-4.

Check host PC for USB 3.0 host controller software updates

Various issues with detecting devices connected to USB 3.0 SuperSpeed hubs may be caused by using older USB 3.0 Host controller drivers.  Generally speaking, drivers from mid 2012 or later tend to work relatively well, when compared to early USB 3.0 host controller drivers released in 2010, 2011, or early 2012.

For Windows 8, simply apply any available Windows Updates. Microsoft provides USB 3.0 host controller drivers for Windows 8 PC’s.

For Windows 7, Windows Vista, or Windows XP, most USB 3.0 host controllers on recent (from mid-2012 onward) software versions work well with currently shipping versions of our hub, as these older Windows versions all used USB 3.0 host controller drivers provided by the respective host controller chip  makers. It is not unusual for customers to need an update to a host PC’s usb 3.0 controller software for normal operation of the hub (since a hub’s drivers are actually loaded from the USB host controller the hub is attached to). Checking your PC manufacturer’s support page is a good first resource for finding USB 3 Host controller driver updates.

For example, one controller we’ve verified that updating driver version resolves several issues with is the NEC/Renesas USB 3.0 host controller used in our PCIe USB 3.0 expansion card. Details on how to check which version of the NEC/Renesas controller chip your system are here.

For assistance determining whether a USB 3.0 host controller driver update is available for your PC, please email with your Amazon Order ID, a note explaining why you are emailing us, and the output from our support tool PlugDebug.

Please do NOT email your support file with no description of what issue you are facing. Only by knowing both what specific troubles your system is having and the details of the system provided by PlugDebug are we able to recommend the right steps for troubleshooting.

Mac OS X

On OS X, simply apply any available App store updates.

For issues specific to ports 1-4, apply firmware version 8581

Plugable’s USB 3.0 7 port Hub is internally comprised of dual VL812 4 port hub chips. A 2nd “downstream” chip is connected to the first port on the “upstream” chip, leaving 7 ports available for connecting external devices (one of the 8 total ports is used connecting the downstream chip to the upstream one).

For this reason, it is crucial to first use ports 5-7 when troubleshooting issues with the 7 port hub. After verifying whether ports 5-7 work normally, making certain ports 1-4 behave normally is much easier.

For hubs running firmware version 8571, some computers may have issues recognizing devices connected to ports 1-4, or with devices connected to these ports not resuming from sleep properly. If you find issues where devices work in ports 5-7, but not in ports 1-4, updating hub firmware to version 8581 should help.

We’ve tested this firmware update utility on 32 and 64 bit Windows 7, 64 bit Windows 8, as well as 32 bit Windows XP with good results. We were also able to successfully update the firmware on a hub running Windows 7×64 in BootCamp (Parallels and other virtual machines, however, will not work).

If you do not have access to a Windows PC with USB 3.0 support (or a BootCamp partition on your USB 3.0 capable Mac) please contact for assistance. To be clear, updating over USB 2.0 connections or from OS X is not supported: only when the hub is detected as a USB 3.0 device on Windows will firmware upgrade be possible. OS X users can find further details on support options and recommended alternatives for this unit at our page on USB 3.0 Hub Support for OS X.

To update hub firmware to version 8581, use the link below to download the update utility, double-click the file, and follow the instructions onscreen.  For further instructions on this update process, or for questions on older units, details are available in the Plugable USB 3.0 Hub Firmware Upgrades post.

Other issues with specific devices

If none of the above steps have resolved issues with a specific device connecting through your hub, please send a mail to and attach the ouptut from our support tool, PlugDebug,  and include your Amazon order ID along with any available details about the device such as manufacturer, model number, and a description of the issue for further troubleshooting assistance. Again, please do NOT email your support file with no description of what issue you are seeing. Only by knowing both what specific issue your system is having and the system details provided by PlugDebug are we able to recommend the right steps for troubleshooting.

One common example is that many USB 3.0 external hard drives and enclosures have firmware updates that resolve issues with detection, wake from sleep, and may optimize transfer speeds to the drive. If you find a particular device operates normally when connected directly to your pc, and the previous steps haven’t resolved issues with a specific device, checking for software or firmware updates such as those below from your devices’ manufacturer is recommended:
