Chip! The DEC-TALK USB can get power from the USB port, a nine volt battery or the included power supply. The deal with USB is that the data drivers are not quite ready. The power part of USB works fine. The device does not have a recharging circuit so the nine volt battery option means you use one battery and throw it away. How many hours on a battery? I'll have to check.
