OK, this is the result, I used su -c '<command>' as it wouldn't work
with plain sudo for some reason:

I started Cheese and suddenly I have video, also pipewire reports a new
audio source as well.

I wonder how this can be made to work automatically. Could it just be a
quirk of this particular USB VID/PID? I note that the PID is not listed
in the hwdata USB IDs.
