76 * There are two hidpp protocols in use, the first version hidpp10 is known
77 * as register access protocol or RAP, the second version hidpp20 is known as
78 * feature access protocol or FAP
80 * Most older devices (including the Unifying usb receiver) use the RAP protocol
81 * where as most newer devices use the FAP protocol. Both protocols are
82 * compatible with the underlying transport, which could be usb, Unifiying, or
83 * bluetooth. The message lengths are defined by the hid vendor specific report
84 * descriptor for the HIDPP_SHORT report type (total message lenth 7 bytes) and
85 * the HIDPP_LONG report type (total message length 20 bytes)
87 * The RAP protocol uses both report types, whereas the FAP only uses HIDPP_LONG
88 * messages. The Unifying receiver itself responds to RAP messages (device index
89 * is 0xFF for the receiver), and all messages (short or long) with a device
90 * index between 1 and 6 are passed untouched to the corresponding paired
93 * The paired device can be RAP or FAP, it will receive the message untouched
94 * from the Unifiying receiver.

2321 * Logitech M560 protocol overview
2323 * The Logitech M560 mouse, is designed for windows 8. When the middle and/or
2324 * the sides buttons are pressed, it sends some keyboard keys events
2325 * instead of buttons ones.
2326 * To complicate things further, the middle button keys sequence
2327 * is different from the odd press and the even press.
2329 * forward button -> Super_R
2330 * backward button -> Super_L+'d' (press only)
2331 * middle button -> 1st time: Alt_L+SuperL+XF86TouchpadOff (press only)
2332 * 2nd time: left-click (press only)
2333 * NB: press-only means that when the button is pressed, the
2334 * KeyPress/ButtonPress and KeyRelease/ButtonRelease events are generated
2335 * together sequentially; instead when the button is released, no event is
2339 * 10<xx>0a 3500af03 (where <xx> is the mouse id),
2340 * the mouse reacts differently:
2341 * - it never sends a keyboard key event
2342 * - for the three mouse button it sends:
2343 * middle button press 11<xx>0a 3500af00...
2344 * side 1 button (forward) press 11<xx>0a 3500b000...
2345 * side 2 button (backward) press 11<xx>0a 3500ae00...
2346 * middle/side1/side2 button release 11<xx>0a 35000000...
