How to launch two Odrive ROS nodes

Hi everyone,
I bought two Odrive and I want to use roslaunch to launch two odrive_ros node.
I’m using a personal computer and connect my PC to the two odrive using two USB port.

However, if I simply and a new tag and change the node name,
I cannot specify which odrive node corresponds to which serial port on my PC.

Do anyone has any idea about this?


according to their documentation you can specify /dev/ttyUSBx as a parameter of the node…
