ADB -> USB Keyboard+Mouse Adapter Firmware

Hi. I am using real Apple ADB Keyboards with recent Apple Macs. I believe Option-Control-Command are swapped somehow. Is there a way to fix that in the firmware? Binary edit is fine to me.

for Mac OS users with brew, you can run "brew install avrdude".
To find your ports you can run "ls /dev/{tty,cu}.*", which will list something like "/dev/tty.usbmodem31101"

Your terminal command would look something like:

avrdude -p ATmega32u4 -P /dev/cu.usbmodem31101 -c avr109 -U flash:w:adb.hex
