USB to USB keyboard protocol converter
Original code from Hasu's TMK firmware. Ported to QMK by Coloneljesus.
This port has been tested only on the Pro Micro variant described in the next section.
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.

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.

Other compatible boards like Arduino's Shield will also work well but I think Sparkfun's needs to be modified.

Also Pro Micro 3.3V(not Mini) or Teensy with mini host shield will work with some fixes on signal/power routing.

Build firmware
Follow normal QMK build instructions to get a binary file. Flashing depends on you hardware.
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.
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 2017/08/16 Port to QMK
