Yeah, I saw this once or twice before.  But I wasn't quite sure what  
it was.  One thing that I've seen people do is short out the power.   
If you short out the power on the Arduino, or put too much of a load  
on it, then the USB bus will automatically kill the power to the  
whole USB bus, including your mouse and keyboard, if that's USB.

My guess is that unplugging the Arduino should fix the problem.  What  
exactly happens for you?  Does the mouse freak out and jump around  
the screen?  I saw that once or twice, that's probably a bug in the  
driver since I can't see how Pd could control the mouse pointer (yet).

Using ReBirth is like trying to play an 808 with a long stick.    -
