USB to USB keyboard protocol converter
======================================

Hardware requirement
--------------------
Arduino Leonardo
http://arduino.cc/en/Main/ArduinoBoardLeonardo

Circuit@Home USB Host Shield 2.0
http://www.circuitsathome.com/products-page/arduino-shields/usb-host-shield-2-0-for-arduino


Build firmware
--------------
$ git clone git://github.com/tmk/tmk_keyboard.git
$ cd tmk_keyboard
$ git submodule init
$ git submodule update
$ cd converter/usb_usb
$ make

You will get usb_usb.hex if you are lucky.
Program your Leonardo with avrdude(or easy-going Arduino IDE):

$ avrdude -patmega32u4 -cavr109 -PCOM17 -b57600 -Uflash:w:usb_usb.hex


Limitation
----------
Only supports 'HID Boot protocol'.
Not support keyboard LED yet.
