Help on USB Audio Interface Driver Issue

[gxb]

Hi I am quite new to this forum and CAS as well. I have an issue on USB audio interface.

 

I installed Windows 8.1 Enterprise. Plugged the interface into a Intel USB 3.0 port and then installed the driver. It did work well.

 

Then I disabled some services through services.msc. I happened to plug the interface into a Intel USB 2.0 port, then it could not be recognized and of course the driver was not loaded. I also tried to plug the interface to a PCIe USB 3.0 port, but everything was good.

 

I uninstalled the driver, and then plugged the interface to Interl USB 2.0 port and reinstalled the driver. Now installation failed. I guess it was caused by service disabling.

 

Who have a clue or thought which service is related to this issue? I enabled Play & Plug, but it did not solve the issue.

 

Thx!
