Re: AttributeError: Roboclaw instance has no attribute '_port'

That error is indicating the comport did not open so it has no instance of _port. Also the motor running out of control when you use the speed commands indicates its not been tuned and the settings saved to the board. You should use Ion Studio to setup and test the speed control settings before trying to use it in ROS.
