Jetson nano Orin USB Ports not working

Hi All,
We have been using the Jetson Orin Nano Dev Kit for R&D purposes without any issues until recently when the USB 3.0 ports suddenly stopped functioning. Currently, there is no output voltage from any of the USB ports.

Upon investigating the AP22811AW5-7 chip, we observed the following voltages with respect to the ground pin:

  • PIN1 (OUTPUT): 0 V
  • PIN5 (IN): 5 V
  • PIN3 (HUB_DSP12_OCP): 3.3 V
  • PIN4 (HUB_DSP12_PWR_EN): 0 V

lsusb -t -v output:

/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/4p, 10000M
    ID 1d6b:0003 Linux Foundation 3.0 root hub
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/4p, 480M
    ID 1d6b:0002 Linux Foundation 2.0 root hub
    |__ Port 3: Dev 2, If 0, Class=Wireless, Driver=rtk_btusb, 12M
        ID 13d3:3549 IMC Networks 
    |__ Port 3: Dev 2, If 1, Class=Wireless, Driver=rtk_btusb, 12M
        ID 13d3:3549 IMC Networks

also attached dmesg file for your reference.

Any guidance on resolving this issue would be greatly appreciated.

If this is really NV devkit and reflash with sdkmanager cannot recover it, please RMA this board.
