64 * There are two hidpp protocols in use, the first version hidpp10 is known
65 * as register access protocol or RAP, the second version hidpp20 is known as
66 * feature access protocol or FAP
67 *
68 * Most older devices (including the Unifying usb receiver) use the RAP protocol
69 * where as most newer devices use the FAP protocol. Both protocols are
70 * compatible with the underlying transport, which could be usb, Unifiying, or
71 * bluetooth. The message lengths are defined by the hid vendor specific report
72 * descriptor for the HIDPP_SHORT report type (total message lenth 7 bytes) and
73 * the HIDPP_LONG report type (total message length 20 bytes)
74 *
75 * The RAP protocol uses both report types, whereas the FAP only uses HIDPP_LONG
76 * messages. The Unifying receiver itself responds to RAP messages (device index
77 * is 0xFF for the receiver), and all messages (short or long) with a device
78 * index between 1 and 6 are passed untouched to the corresponding paired
79 * Unifying device.
80 *
81 * The paired device can be RAP or FAP, it will receive the message untouched
82 * from the Unifiying receiver.

1033 * Logitech M560 protocol overview
1034 *
1035 * The Logitech M560 mouse, is designed for windows 8. When the middle and/or
1036 * the sides buttons are pressed, it sends some keyboard keys events
1037 * instead of buttons ones.
1038 * To complicate things further, the middle button keys sequence
1039 * is different from the odd press and the even press.
1040 *
1041 * forward button -> Super_R
1042 * backward button -> Super_L+'d' (press only)
1043 * middle button -> 1st time: Alt_L+SuperL+XF86TouchpadOff (press only)
1044 * 2nd time: left-click (press only)
1045 * NB: press-only means that when the button is pressed, the
1046 * KeyPress/ButtonPress and KeyRelease/ButtonRelease events are generated
1047 * together sequentially; instead when the button is released, no event is
1048 * generated !
1049 *
1050 * With the command
1051 * 10<xx>0a 3500af03 (where <xx> is the mouse id),
1052 * the mouse reacts differently:
1053 * - it never sends a keyboard key event
1054 * - for the three mouse button it sends:
1055 * middle button press 11<xx>0a 3500af00...
1056 * side 1 button (forward) press 11<xx>0a 3500b000...
1057 * side 2 button (backward) press 11<xx>0a 3500ae00...
1058 * middle/side1/side2 button release 11<xx>0a 35000000...
