Usb device mode not working

Autonomous Machines Jetson & Embedded Systems Jetson AGX Orin

Hi I just got my AGX Orin dev board and updated everything to the latest. But I could not get usb dev mode to work. I connected the usb c port to my ubuntu machine, but nothing pops up. No usb ethernet, no storage. I think I have similar issue with this one. But this one got closed. I’m using the USB-C port next to the 40 pin.

I tried running dmesg | grep --color 'tty' on my host machine as suggested in the setup guide in headless mode. No new tty device is detected on my host machine. I had a TX2 and the usb dev mode works fine.

Thank you in advance

Hi,

Just in case I didn’t miss anything here. Your “AGX Orin dev board” is a NV devkit, isn’t it?

Hi,

Sorry for the confusion. Yes, my device is the Nvidia Jetson AGX Orin Developer Kit.

Thanks

Hi,

The type C that can use as usb device mode is same as the one you use to flash the Orin devkit.

Is your Orin already booting into linux?

Yes,

The Orin is normal. The OS boots up and I did sudo apt upgrade. I also tried rebooting several times.
I tried the cable included in the kit, another usb cable, two different machine (one M1 macbook pro and one Ubuntu 20.04). Neither of these worked.

Thanks

When connect it to your ubuntu host, did the dmesg on your host show anything?

No. The Orin is not shown in dmesg. Here is the output running dmesg | grep --color 'tty' with devkit plugged in.

dmesg | grep --color 'tty'
[    0.083869] printk: console [tty0] enabled
[    0.359243] 00:02: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A

I didn’t only want to know if Orin is showing up. I mean any kind of log in the moment when you connect the usb cable.

Run “dmesg --follow”. Watch this as you connect the USB cable, and copy and paste the logs which show up as you connect USB.
