[Issue with Logitech Webcam and Inateck PCIe USB 3.0 csrd]

Have you tried passing the whole card instead of just the ports? I had a similar problem and passing the whole card fixed the problems.

 

 

I tried using these methods for passing through the entire controller and just the webcam.

They didn't work for me. Is that how you did it?

 

I did the ***GUIDE*** Passthrough Entire PCI USB Controller and New USB Pass Through Method with USB 3.0 at the same time

I took a little bit of work but it wasn't too hard.

 

 

If you post your xml I can see if i can give you a hand
