I just finised up with a program that can control a dynamixel motor and read out a tempsensor on two different virtual serial ports (LUFA: Dual Virtual Serial).
Now to start the dynamixel you have to say in the roslauch file which com/acm port it is connected. And because this can change from time to time, you need to change the com/acm port en build the code over and over again.
With the help of the Serial number of the device, the pc/ros-side can find the com/acm port automatically.
The problem is that the Serialnumber doesnt split up in a serail number for each USB ACM device. So what I have is one Serial Number and two devices.
Is there a way to give each interface/device a Serial number?
Thanks in regards!
