/*
* Logitech M560 protocol overview
*
* The Logitech M560 mouse, is designed for windows 8. When the middle and/or
* the sides buttons are pressed, it sends some keyboard keys events
* instead of buttons ones.
* To complicate things further, the middle button keys sequence
* is different from the odd press and the even press.
*
* forward button -> Super_R
* backward button -> Super_L+'d' (press only)
* middle button -> 1st time: Alt_L+SuperL+XF86TouchpadOff (press only)
* 2nd time: left-click (press only)
* NB: press-only means that when the button is pressed, the
* KeyPress/ButtonPress and KeyRelease/ButtonRelease events are generated
* together sequentially; instead when the button is released, no event is
* generated !
*
* With the command
* 10<xx>0a 3500af03 (where <xx> is the mouse id),
* the mouse reacts differently:
* - it never sends a keyboard key event
* - for the three mouse button it sends:
* middle button press 11<xx>0a 3500af00...
* side 1 button (forward) press 11<xx>0a 3500b000...
* side 2 button (backward) press 11<xx>0a 3500ae00...
* middle/side1/side2 button release 11<xx>0a 35000000...
