Hi,
I have connected 3 usb camera sources to the jetson nano board. The camera is working fine. After sometime the camera gets disconnected. I got the below demsg
dmesg | grep 2-1.2

And when v4l2-ctl --list-devices is entered below is the reply
Failed to open /dev/video0: No such file or directory
Sometimes the camera will fully dissapear and is not recognized even after restarting the jetson. It only works after power on after a shutdown
Is there a method to rescan the usb devices connected or What can be the issue for this?
Thanks in advanced
