Yep, that would do it.

That request is PLAYER_POSITION2D_REQ_MOTOR_POWER, which tries to  
turn on the motor power.  The Roomba doesn't have software-controlled  
motor power, so the roomba driver doesn't support that request.  You  
can ignore this error in your client program (or stop sending the  
request that generates it).
