Umm......at some point, I reread the guidelines for the Trinket contest -- "must be battery operated".

Anyway, long story..short, the HID module will operate from a battery (if you bother to plug one in), but it will operate off of the USB bus just file.

You can ignore any reference of battery stuff in the write-up -- unless you're a stickler for details.
