Hi folks,
I've been running Qubes as my main dev workstation (on a Lenovo T590) for a
good few months now and I've got nearly everything working as I need. The
final niggle is an intermittent webcam issue.
The webcam is recognised fine and I can assign it to my Qube just fine.
I can start a Google Meet session and everything's just dandy.
But after a while (10-20 mins?) Firefox will al of a sudden think it no
longer has a camera available and will no longer send video.
* The witness light on the camera is still on, so the laptop thinks
*something* is using it
* If I try to unmount the camera (it's listed as a USB device) via the
Qubes Devices systray icon I get an error saying "Detaching device ...
failed. Error: 'device 4-8 of class usb not attached to {qube-name}"
* I can restart my usb qube which clears the camera's witness light as well
as the qube mount, and I'm free to re-mount the camera to my qube again.
But Firefox still doesn't recognise it.
* After an hour or so, rebooting the usb qube does sort everything out and
I can use video in a Google Meet again.
Where can I start looking to diagnose what's going on?
Many thanks,
Martin Gladdish.
