Frequently Asked Questions


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

The USB expansion cards derive power from the PCI or PCI Express slot on the motherboard. When high-powered USB devices are connected to the USB expansion card, the power provided by the slot may not be enough to power all of the devices and you should connect additional sources of power. When you troubleshoot issues, you should connect an additional source of power.

Symptoms that you are experiencing power-related issues include certain devices not working correctly, not all of the devices working at the same time, and certain devices not working at all.

Examples of low-powered USB devices include USB mice, keyboards, and flash drives. An example of a high-powered USB device is an external hard drive that does not have an external source of power.
