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

Drawing too much power might have had something to do with a motor I
was running. But I had no problem with the motor using my own arduino

The situation with mis-wiring the pot was independent of the comport
object freezing my kbd and mouse, though. The kbd and mouse froze when
everything was wired up fine (which worked w/ my own arduino code,
just not with comport).

It's now mysteriously worked, the last time I tried it, but the wiring
was all the same as before. So I have no idea, now that it's not
really reproducible...
