The accelerometers/gyro on the Sixaxis are reported in the wrong endianness (ie. not compatible with HID), so this patch intercepts the report and swaps the appropriate bytes over. Accelerometers are scaled with a nominal value of +/-4000 = 1G, maximum value would be around +/-32768 = 8G. Gyro on my device always reports -32768, might need some calibration set within the controller.
