Bug Description
Hi,
I have a USB webcam attached to my ubuntu machine:
Bus 001 Device 002: ID 0c45:600d Microdia TwinkleCam USB camera
this device uses gspca_sonixb:
gilbahat@meadow:~$ lsmod | grep gspca
gspca_sonixb 20480 0
gspca_main 24576 1 gspca_sonixb
videobuf2_vmalloc 20480 1 gspca_main
videobuf2_v4l2 24576 1 gspca_main
videobuf2_common 49152 2 gspca_main,
videodev 225280 4 gspca_main,
the device passes v4l2 tests:
$ v4l2-ctl -d /dev/video0 --all

the device even works with vlc when opened as a v4l2 capture device and picture is detected and displayed.
however, cheese just insists there is no webcam installed, even when run with -d /dev/video0 on the command line.
system details:

Description: Ubuntu Focal Fossa (development branch)
Release: 20.04
$ dpkg -l | grep cheese
ii cheese 3.34.0-1build1 amd64 tool to take pictures and videos from your webcam
expected behaviour:
/dev/video0 appears on the list of usable devices and cheese uses it
observed behaviour:
cheese complains about no video devices being available.
