+USB to USB keyboard protocol converter
+======================================
+See for detail and discussion.
+https://geekhack.org/index.php?topic=69169.0
+
+
+Hardware requirement
+--------------------
+There are two options.
+
+### TMK USB-USB Converter
+You can buy a fully assembled converter from me here.
+
+    https://geekhack.org/index.php?topic=69169.0
+
+### Arduino Leonardo + Circuit@Home USB Host Shield 2.0
+Buying Arduino Leonardo and USB Host Shield 2.0(from Circuit@home) will be better, you won't need even soldering iron.
+
+    http://arduino.cc/en/Main/ArduinoBoardLeonardo 
+    https://www.circuitsathome.com/products-page/arduino-shields/usb-host-shield-2-0-for-arduino-assembled/
+
+Other compatible boards like Arduino's Shield will also work well but I think Sparkfun's needs to be modified.
+
+    http://arduino.cc/en/Main/ArduinoUSBHostShield
+    https://www.sparkfun.com/products/9947
+
+Also Pro Micro 3.3V(not Mini) or Teensy with mini host shield will work with some fixes on signal/power routing.
+
+    https://www.circuitsathome.com/products-page/arduino-shields/usb-host-shield-for-arduino-pro-mini
+    https://www.sparkfun.com/products/12587
+    https://www.pjrc.com/teensy/td_libs_USBHostShield.html
+
+
+
+Build firmware
+--------------
+Build.
+
+    $ git clone git://github.com/tmk/tmk_keyboard.git
+    $ cd tmk_keyboard
+    $ git submodule init
+    $ git submodule update
+    $ cd converter/usb_usb
+    $ make
+
+And Program converter. Push button on TMK converter and just run this.
+
+    $ make dfu
+
+
+In case of Leonardo push reset button then run command. Serial port name(COM17) depends your system. On Linux I got /dev/ttyACM0.
+
+    $ DEV=COM17 make program
+    or
+    $ avrdude -patmega32u4 -cavr109 -b57600 -Uflash:w:usb_usb.hex -PCOM17
+
+
+
+Limitation
+----------
+Only supports 'HID Boot protocol'.
+
+Note that the converter can host only USB "boot protocol" keyboard(6KRO), not NKRO, it is possible to support NKRO keyboard but you will need to write HID report parser for that. Every NKRO keyboard can have different HID report and it is difficult to support all kind of NKRO keyboards in the market.
+
+
+
+Keymap editor
+-------------
+You can editor keymap and download firmware with web brwoser.
+
+- http://www.tmk-kbd.com/tmk_keyboard/editor/unimap/?usb_usb
+
+
+
+Update
+------
+2014/12/11  Added Hub support(confirmed with HHKB pro2)
+2016/09/10  Unimap editor support
+2016/10/18  Fix LED state at startup
+
