85 | * There are two hidpp protocols in use, the first version hidpp10 is known | |
86 | * as register access protocol or RAP, the second version hidpp20 is known as | |
87 | * feature access protocol or FAP | |
88 | * | |
89 | * Most older devices (including the Unifying usb receiver) use the RAP protocol | |
90 | * where as most newer devices use the FAP protocol. Both protocols are | |
91 | * compatible with the underlying transport, which could be usb, Unifiying, or | |
92 | * bluetooth. The message lengths are defined by the hid vendor specific report | |
93 | * descriptor for the HIDPP_SHORT report type (total message lenth 7 bytes) and | |
94 | * the HIDPP_LONG report type (total message length 20 bytes) | |
95 | * | |
96 | * The RAP protocol uses both report types, whereas the FAP only uses HIDPP_LONG | |
97 | * messages. The Unifying receiver itself responds to RAP messages (device index | |
98 | * is 0xFF for the receiver), and all messages (short or long) with a device | |
99 | * index between 1 and 6 are passed untouched to the corresponding paired | |
100 | * Unifying device. | |
101 | * | |
102 | * The paired device can be RAP or FAP, it will receive the message untouched | |
103 | * from the Unifiying receiver. | |

2441 | * Logitech M560 protocol overview | |
2442 | * | |
2443 | * The Logitech M560 mouse, is designed for windows 8. When the middle and/or | |
2444 | * the sides buttons are pressed, it sends some keyboard keys events | |
2445 | * instead of buttons ones. | |
2446 | * To complicate things further, the middle button keys sequence | |
2447 | * is different from the odd press and the even press. | |
2448 | * | |
2449 | * forward button -> Super_R | |
2450 | * backward button -> Super_L+'d' (press only) | |
2451 | * middle button -> 1st time: Alt_L+SuperL+XF86TouchpadOff (press only) | |
2452 | * 2nd time: left-click (press only) | |
2453 | * NB: press-only means that when the button is pressed, the | |
2454 | * KeyPress/ButtonPress and KeyRelease/ButtonRelease events are generated | |
2455 | * together sequentially; instead when the button is released, no event is | |
2456 | * generated ! | |
2457 | * | |
2458 | * With the command | |
2459 | * 10<xx>0a 3500af03 (where <xx> is the mouse id), | |
2460 | * the mouse reacts differently: | |
2461 | * - it never sends a keyboard key event | |
2462 | * - for the three mouse button it sends: | |
2463 | * middle button press 11<xx>0a 3500af00... | |
2464 | * side 1 button (forward) press 11<xx>0a 3500b000... | |
2465 | * side 2 button (backward) press 11<xx>0a 3500ae00... | |
2466 | * middle/side1/side2 button release 11<xx>0a 35000000... | |
