Hello,

 

at first i would like to say: im a total beginner at virtualization and unraid.

so i after following the guide to set up the unraid os and the VM. so far so good. the windows 10 is running and it works, but i try to passthrough a usb DVB-S2 Card. I want to run a DVB-Viewer Server on the windows system. So i checked the passthrough for the usb, but nothing appeared in the Windows system. so i looke into the log and it said:

I have exactly the same problem with my windows 7 VM.

 

I get the same Warning in the Log file:

I did not try to passthrough the usb controller yet, just the device.

Any help would be nice

Hi.

 

I had the same problem and editing the XML file in this manner resolved it for me. Keep in mind that the post linked says that this only works for Windows 8 and above (no Win7)

 

Ta,

by any chance is the USB port USB3?
