Atmel has a similar part (AT90USB1287) and has a devkit, AT90USBKEY,
that might save you some work. It's a USB OTG 2.0 device, $30, has the
right dongle, and has a pair of 64Mbit flash chips on board. The power
supply is spec'd to 8-15V, but might be coaxed to run off something
lower. Digikey/Mouser/Arrow stocks 'em.
