Hi,

Try, Changing the baud rate of the ros node which you are running. Below are the instructions

cd <catkin_ws>/src/rosserial/rosserial_python/nodes
gedit serial_node.py

here find the line where your baud is set, and try changing it to match the baud rate of your device (which you can find it in the preferences.txt in your sketchbook )

baud = int(rospy.get_param('~baud','9600'))

It does connect for a brief moment successfully and then it throws up an error for me, I'm using groovy on 12.04. Please Let me know if can find a way to stay connected for a longer time without getting disconnected. good luck.

Edit: may be this thread The threads, here, helps, and here looks similar to what I encountered. Also to be noted, No changing Default params, as pointed out by the moderator.
