 ADB to USB keyboard converter
 =============================
-This firmware converts ADB keyboard protocol to USB.
-You can use TMK Converter, PJRC Teensy2.0 and other USB AVR MCU(ATMega32U4, AT90USB64/128 or etc) for this. But binary size is probably more than 10KB and it won't fit into 8K flash.
