I’m having trouble with using two different webcams: Logitech C270 and Azurewave Integrated Camera (Thinkpad T14s)
I’m aware of other threads on the topic and have already increased memory for sys-usb
to 1024MB (which was the solution in Unable to connect my Webcam to any AppVM; connects and then fails).
The behavior is different than described in the other threads:
- Webcam gets connected to AppVM
- Webcam briefly shows up in settings (MS Teams or Jitsi)
- Webcam disappears again
The behavior is identical for both webcams and across different AppVMs.
Logitech C270:
