Arduino plug in

[BunnyIcon]

Hello, I'm a beginner on Jeston. I'm using Jetson AGX Xavier with ROS installed on it.

When I tried to connect ROS and Arduino UNO, it failed. It always showed /dev/ttyUSB0, /dev/ttyUSB1, /dev/ttyUSB2, /dev/ttyUSB3 for 'ls /dev/ttyUSB*'. The same four ports are shown in Arduino IDE. It doesn't matter whether Arduino plugged in. And I failed to download code from Arduino IDE to Arduino.

It's different from what Jetson Nano and Arduino tutorials. So could anyone tell me how to achieve communication between Arduino UNO and Jetson AGX Xavier? Thanks in advance!
