I have been looking into how to upgrade firmware to the 16u2 USB IC on the Due and it seems you need to use an ISP or other Arduino setup as an ISP to program the 16u2.

Silly question though, would it not be possible to flash the 16u2 by loading ArduinoISP onto the Due, connecting the SAM3X8E SPI port to the 16u2 ISP port, and then running the Due as an ArduinoISP though the native USB port?

Please pardon my ignorance if this is a retarded idea...  XD
