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.
dom0:00_14.0 USB controller: Intel Corporation Sunrise Point-LP USB 3.0 xHCI
Controller sys-usb
(no-strict-reset=True)
dom0:3b_00.0 USB controller: Intel Corporation JHL6540 Thunderbolt 3 USB
Controller (C step) [Alpine Ridge 4C 2016]
Would it be possible to use the thunderbolt controller for that purpose? It
doesn't seem to be used right now.
Possibly! Shouldn't hurt to try. You'll need to switch that AppVM to HVM
mode and disable memory balancing to attach a device to it. Can always
switch it back to PVH if it doesn't work.
