I connected a camera to xavier nx via PCIE to USB 3.0, and it was able to detect the device when powered on normally, but after reboot, I couldn’t detect the device。
After power on:

syslog.txt (654.8 KB)
Fist nx is powered on normally, the pcie usb is working properly,but I restarted it a few times, the pcie usb can not mount devices.After restarting a few more times, the pcie usb2.0 device is mounted, not usb3.0.
When I use 32.6.1 system, it works fine after reboot.
