When you troubleshoot issues with a USB controller card, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • USB cables

  • USB devices

  • USB controller card

To test your setup components, try the following:

  • Use the USB cable, device, and controller card in another setup to see if the problem is with the components or the setup.

  • Use a different USB cable, device, and controller card in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

When you test the USB device and controller card, it is recommended that you do the following:

How To

To confirm that Windows detects your expansion card, complete the following:

  1. Press the Windows key+R, type devmgmt.msc, and press Enter.
  2. In Device Manager, under the appropriate heading, confirm that your expansion card is listed and that there isn't an exclamation mark next to it.  For example, a USB controller card would be under Universal Serial Bus controllers.

Your expansion card is listed according to the name of the chipset. To determine the name of the chipset of your expansion card, navigate to www.StarTech.com and look on the Technical Specifications tab for your product.

Before You Buy

Yes, it is required to use the included power connector with this card. Additional power is required above what the PCI or PCI Express slot on the motherboard is able to provide. If the power connector is not used with the card, the devices used with the card are not likely to function correctly, and the ports on the card will not be able to output the maximum amount of power USB is capable of.

Fast, but needs lots a big power supply

By: Genopsyde - 01/03/2014
Have a PC service shop and installed a half dozen of these.  On the machines that had a 400W power supply, USB sticks worked, but USB2.0 and 3.0 docking stations did not.  Once upgraded to a 500W power supply, a single USB dock would work on one port but could not run two docks.  Once finally upgrading the PSU on each machine to 600W, both USB ports worked at the same time with USB2.0 and 3.0 docking stations.  These are definitely power hungry.

Power connection not optional

By: TedB - 02/25/2014
Documentation states power connection is optional. My experience with two of these in three separate computers indicates that the power connection is required, even in one with a 750w supply. I could not get any USB devices to work unless the power connection was in place. After doing that everything worked fine.

Not bootable

By: David - 04/02/2014
I wanted to boot from this card. I have to give it 5 stars because it does everything that StarTech claims. I always want to do something different.

It does require the "optional" SATA power connector. Tried the card in two different systems. Drivers installed and all showed well. But, nothing would respond when plugged in. Not a flash drive, keyboard, or disk drive. After plugging in the SATA power connection and rebooting, everything worked as expected. Nice and fast.
