Werbel

+1, same problem here, fresh unit, updated everything, steamvr beta (not updated between working and unworking state). It got same issue after long game session with no issues, now it's permament. I'll try to debug it but just giving a short "it's serious" note. ####EDIT_SOLVED### I managed to solve this problem by disabling camera through steamvr.vrsettings, removing all usb drivers through steamvr/Developer tab (on the very bottom), then resetting PC and repairing the headset.
