Title: better Arduino device regexp

Previous regular expression matches e.g. `/dev/usb`, which is undesirable. All Arduinos should show up as `/dev/tty(USB|ACM|S)[number]` (see [Arduino docs](http://playground.arduino.cc/Linux/All); `ttyS0` is reportedly for some clones or other non-standard *duinos).
