How to find PORT number on a Jetson AGX Orin?

[trannhuquynh1406]

Hello Team,
I am trying to send my data read from my camera to an another board. both of my devices, the camera and the board are connecting to Jetson AGX Orin through USB Type-A Ports. I am having issue with defining which port is connecting to which device. what I am trying to get can be easily done in Windows using Manager Device but I cannot find anyway to find on jetson. I am not planning to open up the Jetson just to find if there are any labels written next to each USB port. there is nowhere on the NVDIA website that specifies this information. Could you help me on this? Thank you in advance!

For more info, i used the command udevadm info -a -n dev/ttyUSB0 to find if it can recognize what device connecting to that port but only the board is recognized. the camera cannot be detected. i can only do it with ttyUSB0 because that’s the only dev/ttyUSB i can find using ls/ dev. i also try the udevadm command with ttyS0/1/2/3, but my camera is still not detected. The camera is working ok though.

Hi,
If the camera supports USB Video Class(UVC) driver, you should see the device node such as /dev/video0. And can capture frame data through v4l2 interface. Please check if the node is present and try the commands:

Sorry, but none of the command works and there is no node named /dev/video

anyways, my question is could you give me the name/port number of each of the USB-Type A on jetson agx orin?

Hi,
Please try the commands and see if you can get the information:

$ lsusb
$ lsusb -v

I will suggest that you also monitor “dmesg --follow” while you plug in the device at a particular port. See what log lines appear due to that plugin (and post a copy of what log lines occur).
