I'm trying to use a C920 USB camera on a Thinkpad X1 Carbon 6gen, latest Qubes4. The VM is running debian-9, but i also tried fedora-26. I tried both connecting the camera directly to a USB port of the Thinkpad and via a powered USB hub.
Qubes shows the device as still being attached to the VM. I can detach and reattach without problems. Forwarding the Thinkpad's internal camera works fine. Are failures with particular USB devices to be expected? Does anyone know a good external webcam that works?
Yes, some devices don't work well through redirect. If you have a spare USB controller (not in use for your mouse & keyboard) you can assign it directly to the VM and then connect the webcam, but you lose isolation between that controller and the VM.
