2012-08-09 08:14:21 -0500 asked a question MiniMax not working with new notebook configuration

I have purchased a new notebook and followed the setup instructions here: http://www.ros.org/wiki/mini_max_defs/Tutorials/Netbook%20Setup%20%28Diamondback%29

But I am using ros electric - could not find different instructions for electric so I just modified these. Base tests fine One of the buttons test fine Kinect vision test fine None of the servos appear to be recognized

Any help??
