I have a Windows 10 VM with a ASMedia USB 3.1 card. Previously everything worked fine but since I upgraded to unRaid 6.2 I can no longer use USB 2 devices. USB 3 devices still work.

I have no idea what to do and searching has gotten me nothing useful (although I did find people with the same issue in non-virtual environments). If someone could point me in the right direction it would be much appreciated.

 

Ideally I'd like to have USB 2 and USB 3 comparability but I'd accept a solution that reduces me to only USB 2.

 

I never like to change two things at once but because of the issue last week with the update problem after I had just upgraded Windows 10 to the anniversary update and then couldn't reboot unRaid so ended up having to upgrade unRaid to 6.2 at same time. So I can't even be certain which of the two is the problem.

I believe I had the same issue in 6.1.x using certain USB 3.1 cards.  I can't say for certain if it's an issue in software, hardware, or maybe a little of both, but in the meantime, we recommend folks get standard USB 3.0 controllers as these new 3.1 controllers seem to be a little more buggy with virtualization use-cases still.

It worked previously but if I have to I'll just buy something else. My initial thought was to just buy a USB 2 card but those are rather difficult to find.
