I have been using the rosserial_arduino in order to run a ROS node on arduino.
I have the following error:
[ERROR] [WallTime: 1433855869.447165] Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino
But, If I use the Arduino IDE before run the node it works fine.
[INFO] [WallTime: 1433858173.848825] Note: publish buffer size is 512 bytes [INFO] [WallTime: 1433858173.849108] Setup publisher on /joystick_raw [lhd_msgs/Joystick] [INFO] [WallTime: 1433858173.855225] Note: subscribe buffer size is 512 bytes [INFO] [WallTime: 1433858173.855483] Setup subscriber on /leds_ocu [lhd_msgs/Leds]
If I disconnect the arduino, and I connect it again doesn't work again.
Is not a problem with the permissions of the USB.
Can you help me out?

do you have hydro installed and did you compile the libraries with groovy?!?!
