Xavier UAC Camera has system error

Hi We use Xavier kit connected with UAC camera, but sometime the system crahed,

we have to lose power before restart it, after power on the log was cleared.
also found another problem,
when camera has this issue, we plugged in another USB3.0 device. it cannot be recognized either.

system reboot does not work either, must be powered off
please help, thanks

Please share brand and model ID(such as Logitech BRIO webcam) of the UAC camera. The issue should be triggered by the specific device. Would like to get more information about the camera.

And please check if the port goes back to normal after disabling/enabling the regulator. May refer to
USB Load Switches - #23 by DaneLLL
If it works, you can reset the regulator to revive the port without power off.

Hi Dane:
its use our own designed depth camera, below its dmesg log, please check,thanks

We would suggest do compliance test to the camera to make sure the signals are good and stable. Without the test the singals may not be good and can trigger issues.

Hi Dane:
we use our own design camera, has test Intel realsense camere, when connect three realsense cameras, will has the same issue, but use two camera, will not,

Each realsense camera takes significant bandwidth and power, so on Xavier developer kit, we suggest use the type-A port and two type-C ports. To connect each realsense camera to one port. One to type-A port, one to type-C port with type-C to A adapter, and the other to one to type-C port with type-C to A adapter. On your custom board, we would suggest do the same. Better to connect each camera to one rootport.

Hi Dane:
still need your help for below issue, thanks

Form the log it looks like power supply is not stable or insufficient. Suggest you shift cameras to the type-C ports. And make sure the camera has done compliance test.

Hi Dane:
thanks for you reply,
Our camera use independent power supply, dont have done the compliance test right now, still have following error:
