We use a carrier board designed by our company plus Fintek 75114 GPIO, and we will find the USB disappearing problem during long-term testing. This happens whenever GPIO is executed.

Try delaying the delay for 1 to 3 seconds. If the situation takes longer, it will still happen.
Tested Jetpack 5.1.1 BOOT from USB, P3509+p3767, and found that when this happens, the system screen will go black and there will be no response. The guess is that the BSP is installed on the USB and the USB is lost.
This problem does not occur with other USB devices (USB Disk/USB to COM/USB to SSD…),
Now Orin NX/Orin NANO can see this problem
, now we try to turn on and off the USB root port to test, do you have any suggestions?
