USB ports fail after reboot

System characteristics:
Jetson AXG Xavier 16GB
Jetpack 4.5.1
L4T 32.5.1

Hi. I’m recently flash an AGX Xavier with the above characteristics. After installation, I reboot the device and, after it, any USB port could detect physical connected devices.
I connected a mouse to see if the USB port supply voltage, but not. The led mouse was off all the time.
I had to restart the device manually (with the reset button) and, after it, the USB ports work correctly.
The problem is that it is not the first time it happens. Previously, I had the same AGX Xavier with Jetpack 4.4.1 and the same problem happened.
This is an unusual behaviour and I want to understand what is happening.

Thank you for your help.

Once you run into the error again, can you use either serial console or ssh and post a log of dmesg? For example, you could create a log file with “dmesg > log_dmesg.txt”. Or, if using serial console with its logging enabled, simply run the command “dmesg” and the log would contain this. Serial console is better since it could in fact start logging prior to ever powering up the Jetson, and then running “dmesg” in the serial console logging (then no matter what happens it would be recorded to the host PC). Mostly I’m interested in seeing what dmesg reports right after the error occurs, but it would also be useful to see what comes before this happens.
