ZED camera detected by USB but not recognized by SDK and apps

Hardware ZED2
1

I have a Zed box Orin nx 16Gb and a Zed 2i camera.
Everything was working fine for about a month (maybe a bit longer), but recently I started getting the message “camera not detected”…

I checked lsusb, and the Jetson USB ports do recognize the camera:

I can’t understand what the problem is.
I tried to reboot jetson but it is not help.
We tried to replug usb and camera started working but it print “camera not detected” again in some time.
We’re planning to try replacing the USB cable soon. Do you have any thoughts on what might be causing this issue and how we could solve it?

It seems that issue was on my side.
The first time, it was likely caused by a hardware failure.
The second time, I accidently launched a camera test service that opens the camera, closes it and exit the script. However, the service had a restart always policy, which likely caused led to failure.
