The problem was caused when analyzing logs from controller. Tried to understand does device /dev/video2 exist or not (USB-camera). Task is to suggest utility to detect this. The simplest way is to save ls /dev/ output to some file, but maybe more detailed information can be obtained. @iakov , maybe you can suggest something?
[x] lsusv -v
[x] v4l2-ctl -d /dev/video2 --all -- what is /dev/video2 does not exist?
Useful if present in firmware image:
