USB devices are not detected on windows 7.

Hi EricPatton,

Thank you for posting in the Microsoft Community.

Apart from the issue, how are you doing today?

You have an issue with USB device not being detected on Windows 7. This can be really frustrating for you and I appreciate the efforts that you have put in. Let us work together as a team and try to get this issue fixed.

Let us start with few questions-

1)    Do you get any error message or error code?

2)    Are the USB devices detected on a different computer (running the same Operating System)?

3)    What is the make and model of the computer?

4)    Have you made any other changes on the computer?

I would like more information regarding the issue.

Method 1-

I would have you try connecting the device to a different USB port and check.

Method 2-

I would have you run the fixits-

Method 3-

I would have you reinstall the USB controllers.

Refer the steps-

a)       Click Start, then type device manager in the Search box, and then click Device Manager.

b)      Expand Universal Serial Bus controllers. Right click a device and click Uninstall. Repeat for each device.

c)       Once complete, restart your computer. Your USB controllers will automatically install.

Method 4-

I would have you download and install the latest drivers for the USB controllers and the Chipset from the manufacturer’s website.

 Note: You can ask the computer manufacturer for assistance. Installing the Chipset drivers are at your own risk.

Do let us know if you need further assistance. We will be happy to help. We, at Microsoft strive towards excellence.
