Host is Windows 10 (10.0.18363.592), I have tried Virtual Box 6.0.14 and 6.1.0 back and forth, extension pack is installed properly.
The guest is Windows 7. The USB redirect works all the way until today, I don't know what really happened, then it stopped working. It only happens to one particular USB device, others seems to be fine. If I stop USB redirect this particular device shows up in my host immediately.
Any idea how can I troubleshoot this strange issue?
