The intent of the Initialize call was to test the serial number received from the Pi-detector, but I didn't account for the possibility of CPiDetector returning DEFAULT_SERIAL_UNKNOWN, which it does if the requested device hadn't been found. I'm preparing a fix for this that I will submit via SVN as soon as possible.


The ultimate issue is this: The Pi-detector only tested serial numbers up to 250. I've doubled this for now, but this is a stop-gap measure that causes an ugly pause in the device adding process while it probes the serial numbers; I will need to seek a different approach to detecting the motors.


I'll report back after fixing/testing and committing/uploading the device adapter.
