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.

2273 * Logitech M560 protocol overview
2275 * The Logitech M560 mouse, is designed for windows 8. When the middle and/or
2276 * the sides buttons are pressed, it sends some keyboard keys events
2277 * instead of buttons ones.
2278 * To complicate things further, the middle button keys sequence
2279 * is different from the odd press and the even press.
2281 * forward button -> Super_R
2282 * backward button -> Super_L+'d' (press only)
2283 * middle button -> 1st time: Alt_L+SuperL+XF86TouchpadOff (press only)
2284 * 2nd time: left-click (press only)
2285 * NB: press-only means that when the button is pressed, the
2286 * KeyPress/ButtonPress and KeyRelease/ButtonRelease events are generated
2287 * together sequentially; instead when the button is released, no event is
2291 * 10<xx>0a 3500af03 (where <xx> is the mouse id),
2292 * the mouse reacts differently:
2293 * - it never sends a keyboard key event
2294 * - for the three mouse button it sends:
2295 * middle button press 11<xx>0a 3500af00...
2296 * side 1 button (forward) press 11<xx>0a 3500b000...
2297 * side 2 button (backward) press 11<xx>0a 3500ae00...
2298 * middle/side1/side2 button release 11<xx>0a 35000000...
