Bug Description

I have two USB video devices, a Logitech Webcam (first device, /dev/video0) and a CZUR book scanner (basically a camera, second device, /dev/video2), both working in applications such as guvcview, vlc, OBS or webcamoid:

v4l2-ctl --list-devices
UVC Camera (046d:0825) (usb-0000:00:14.0-1.3.1):
/dev/video0
/dev/video1
/dev/media0

CZUR (usb-0000:00:14.0-1.4.2):
/dev/video2
/dev/video3
/dev/media1
However, in Cheese I cannot access the CZUR book scanner: In the GUI, the menu to choose a device is greyed out showing only the UVC camera, on the commandline cheese -d CZUR falls back to the UVC camera I obtained the device name with

udevadm info /sys/class/video4linux/video2 | grep ID_V4L_PRODUCT
E: ID_V4L_PRODUCT=CZUR
and when I replace the device name with dconf editor Cheese falls back to the UVC device again.

This is the output of gst-device-monitor-1.0 with respect to the first and second video device:

gst-device-monitor-1.0 Video
