USB cameras are automatically mounted to ubuntu. I have a case where i have multiple USB cameras in use. I'm mounting each camera on a different port on the laptop.
Sometimes during boot, camera 1 will be disconnected, but camera 2 will be connected, and camera 2 will be assigned to /dev/video1, however the rest of my software assumes/dev/video1 is linked to the camera 1.
What i would like is for if camera 1 is disconnected, then camera 2 will mount itself to its right location - /dev/video2 - and I can keep working.
Since these are USB devices i know they have a unique id. But i dont know anything about mounting video points enough to make this work.

For me, I just needed to run ls /dev/v4l/by-path/ The camera's USB port is consistently updated there, you can check by switching the camera on and off and watching its path value change there.
Alternatively, you can run ls /dev/v4l/by-id/, but this didn't work for me because all my cameras had the same ID. Specifying by USB port seems to work better for my situation.
