Hello,

I am trying to get communication working over the Native USB port (/dev/ttyACM1) on the Arduino Due, which is rated USB3.0. I have already managed to setup communications over the Programming port (/dev/ttyACM0) with a basic publisher/subscriber and works pretty well with rosserialpython. I want to take advantage of the USB port speed to have faster communication rates with my computer and also be able to debug through Serial of the Programming port (IDE). I have modified the ArduinoHardware.h from the roslib library according to these posts:

https://answers.ros.org/question/264764/rosserial-arduino-due-sync-issues/

The command is:

rosrun rosserial_python serial_node.py _port:=/dev/ttyACM1 _baud:=115200

Where /dev/ttyACM1 is the native port as indicated by the IDE. The messages shown are :

[INFO] [1524132033.924200]: ROS Serial Python Node
[INFO] [1524132033.926728]: Connecting to /dev/ttyACM1 at 115200 baud
[ERROR] [1524132051.031280]: Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino

To the question, Can communications be achieved through rosserial over the Native USB port?

I am using Ubuntu 16.04.03 64bit with ROS Kinetic. Thank you!
