Hello,

I am trying to set up an external USB-to-CAN adapter on my Jetson Orin NX running Ubuntu 22.04 with JetPack 6.2, but the device is not being recognized as can1.

System Details:

  • Jetson Board: Jetson Orin NX
  • OS: Ubuntu 22.04
  • JetPack Version: JetPack 6.2
  • Kernel Version: (Run uname -r 5.15.148-tegra )
  • CAN Adapter: OpenMoko, Inc. Geschwister Schneider CAN adapter (ID: 1d50:606f)
  • Existing CAN Interface: The Jetson board already has a built-in can0
  • Tools Installed: can-utils
  • Modules Loaded: can, can_raw, can_dev

lsusb

Bus 001 Device 005: ID 1d50:606f OpenMoko, Inc. Geschwister Schneider CAN adapter

Hi chaud324,

Are you using the devkit or custom board for Orin NX?

Do you just connect the USB-CAN adapter on your board?
(i.e. do you load any driver for your adapter?)

Please share the full dmesg for further check.

I am using Amazon.com: USB CAN Converter Module for Raspberry Pi 5/4/Pi3B+/Pi3/Pi Zero(W)/Jetson Nano/Tinker Board and Any Single Board Computer Support Windows Linux Mac OS Android Venus OS : Electronics (USB CAN Converter Module for Raspberry Pi 5/4/Pi3B+/Pi3/Pi Zero(W)/Jetson Nano/Tinker Board and Any Single Board Computer Support Windows Linux Mac OS Android Venus OS0

Yes I just connected on USB to can on Jetson. It is not getting recognize

Here is the full dmesg log after connecting the USB-to-CAN adapter:

Could you run lsusb before and after you connect the USB-CAN adapter?

Or have you tried to connect this adapter on an Ubuntu host PC to check if it could be recognized?
