Please help me resolve this issue.
I have connected two cameras via a USB hub, and this setup works fine on all my other Jetson Nano devices. However, with one specific Nano (deployed in a truck), I am facing the issue shown in the attached logs.
From the dmesg logs, I can see some errors, but I am unsure whether the problem is due to the driver removing the cameras or if it’s caused by a faulty cable. Any guidance would be appreciated.

Looks like a hardware problem that signal has some issue.
My question is still there,
The log gives other error. I don’t know what is the point that you want to know about “disconnection”.
If the device cannot work could consider “disconnection” to you, then yes, it is disconnected.
This dual camera is not working on remote truck. The log shows it has bad cable, due to which it is powering off usb pad 1.
Plz explain
I already explained… what else do you want to know here?

i just request you to please explain each log statement. what is happening?
The log gives -71 error no.
[ 458.421036] uvcvideo: Failed to set UVC probe control : -71 (exp. 26).
[ 459.966806] uvcvideo: Failed to set UVC commit control : -71 (exp. 26).
[ 460.007014] uvcvideo: Failed to set UVC commit control : -71 (exp. 26).
[ 460.066279] uvcvideo: Failed to set UVC probe control : -71 (exp. 26).
[ 460.072983] uvcvideo: Failed to set UVC probe control : -71 (exp. 26).
And -71 mostly means there is usb signal issue. That is all this log is doing. Rest of things is just lots of -71 error repeating print.
