Hi guys,

 

Have an issue where I'm trying to pass a USB 3 key to a Windows 10 VM. I select it in the edit VM settings, save and start the VM.

 

The VM itself doesn't show the UDB drive and when I look at Device Manager it's telling me that the mass storage device cannot start (Code 10).

 

Any ideas?

 

Here's my XML

Stop your vm and edit it from the webGui. Near the bottom you will find a USB mode option. Set that to USB 3. Save and start your vm and report back your success!
