UR22C Audio Interface Stopped Working after 2 hours

Cubase 11 Pro user. UR22C was showing up in Studio settings then disappeared! Lights light. No sound. Cannot re-install drivers! Deleted entire folder but still cannot re-install drivers. Removed from Device Manager expecting it to show again after re-boot. Now gone. Worked for a few hours then nothing. Don’t want to send it back if there’s a “fix”. Found several others complaining online about same problem. Should I trust the Steinberg hardware or go with another manufacturer? Or, is there a “fix” for this? +48V was not turned on. Nothing was done to “cause” this failure. Please advise if you have any feedback, positive or negative. Thanks! … Jurisdictionary
