This is more or less the programmer used on the Arduino Due (and maybe other Arduino
versions as well). The firmware has been completely rewritten and the Arduino version is
incompatible with this hardware.
The programmer requires both the USB 5V supply and the 3.3V supply from the SAM3X8C plug
in board to function.
