[PD] pduino/comport w/ arduino freezes keyboard and trackpad on Macbook

[David NG McCallum]

Hi HC,

I've had the problem of the USB bus being killed because to much power
was drawn, but it was because I plugged a pot into the wrong ports.

This time, the kbd and mouse just freeze, no other indications of anything else.

So if unplugging the arduino will get my mouse and kbd back, do you
have any suggestions of how I could actually use pduino if I can't
leave it plugged in?
