[vfio-users] USB enumeration (uPD720201)

[Brett Foster]

Hi,

I have a uPD720201 USB 3.0 controller card installed and mapped to my VM.
Many devices work fine, however a number of devices fail to enumerate. For
example, I have tried 4 different USB hubs (2 and 3). Some flash/disk
drives work while others don't. My USB CAN/LIN USB adapter doesn't work.
Some devices are USB 3. Some are USB 2.

I've never seen this kind of behaviour before. Does anybody have experience
with this controller?

Brett
