92 | * There are two hidpp protocols in use, the first version hidpp10 is known | |
93 | * as register access protocol or RAP, the second version hidpp20 is known as | |
94 | * feature access protocol or FAP | |
95 | * | |
96 | * Most older devices (including the Unifying usb receiver) use the RAP protocol | |
97 | * where as most newer devices use the FAP protocol. Both protocols are | |
98 | * compatible with the underlying transport, which could be usb, Unifiying, or | |
99 | * bluetooth. The message lengths are defined by the hid vendor specific report | |
100 | * descriptor for the HIDPP_SHORT report type (total message lenth 7 bytes) and | |
101 | * the HIDPP_LONG report type (total message length 20 bytes) | |
102 | * | |
103 | * The RAP protocol uses both report types, whereas the FAP only uses HIDPP_LONG | |
104 | * messages. The Unifying receiver itself responds to RAP messages (device index | |
105 | * is 0xFF for the receiver), and all messages (short or long) with a device | |
106 | * index between 1 and 6 are passed untouched to the corresponding paired | |
107 | * Unifying device. | |
108 | * | |
109 | * The paired device can be RAP or FAP, it will receive the message untouched | |
110 | * from the Unifiying receiver. | |

2477 | /* | |
2478 | * Logitech M560 protocol overview | |
2479 | * | |
2480 | * The Logitech M560 mouse, is designed for windows 8. When the middle and/or | |
2481 | * the sides buttons are pressed, it sends some keyboard keys events | |
2482 | * instead of buttons ones. | |
2483 | * To complicate things further, the middle button keys sequence | |
2484 | * is different from the odd press and the even press. | |
2485 | * | |
2486 | * forward button -> Super_R | |
2487 | * backward button -> Super_L+'d' (press only) | |
2488 | * middle button -> 1st time: Alt_L+SuperL+XF86TouchpadOff (press only) | |
2489 | * 2nd time: left-click (press only) | |
2490 | * NB: press-only means that when the button is pressed, the | |
2491 | * KeyPress/ButtonPress and KeyRelease/ButtonRelease events are generated | |
2492 | * together sequentially; instead when the button is released, no event is | |
2493 | * generated ! | |
2494 | * | |
2495 | * With the command | |
2496 | * 10<xx>0a 3500af03 (where <xx> is the mouse id), | |
2497 | * the mouse reacts differently: | |
2498 | * - it never sends a keyboard key event | |
2499 | * - for the three mouse button it sends: | |
2500 | * middle button press 11<xx>0a 3500af00... | |
2501 | * side 1 button (forward) press 11<xx>0a 3500b000... | |
2502 | * side 2 button (backward) press 11<xx>0a 3500ae00... | |
2503 | * middle/side1/side2 button release 11<xx>0a 35000000... | |
