Public bug reported:
I've got two webcams: one of them is built in to my Lenovo T14s (running
Ubuntu 20.04.4), and the other is an external USB device. They used to
have obvious names: one was called something like "Integrated Camera C"
and the other was called something like "HuddleCamHD". Strangely, they
have both been renamed to be "Video Capture 4", which means I can't
easily distinguish between them when switching cameras in tools such as
Zoom or OBS Studio. Here's some output showing this:
$ v4l2-ctl --list-devices
Video Capture 4 (usb-0000:00:14.0-5.2.3):
/dev/video2
/dev/video3
Video Capture 4 (usb-0000:00:14.0-8):
/dev/video0
/dev/video1
Likewise, I'm seeing precisely the same issue on my desktop computer,
which is also running Ubuntu 20.04.04:
Video Capture 4 (usb-0000:00:14.0-3.4.3):
/dev/video0
/dev/video1
I'm running kernel version 5.13.0-30. This error first occurs with
kernel version 5.13.0-28. If I boot with an earlier version, it detects
the webcam names just fine.
