Looks like there was an update in the turtlebot code: https://github.com/turtlebot/turtlebo...

Try setting TURTLEBOT_SERIAL_PORT to the device your create is listening to (probably /dev/ttyUSB0). I updated the hydro wiki page to reflect this.

The problem still persists with no change. is this specific to turtlebot in ros indigo ?

Hydro and indigo should be the same in this regard. Next step would be to check that there isn't a bug in the python create driver code. Add some printf's to make sure this parameter is getting through.
