23	*
24	*
25	* Notes:
26	*
27	* - The auxiliary device commands are very similar to keyboard commands.
28	* Most keyboard commands which do not specifically deal with the keyboard
29	* (enable, disable, reset) have identical counterparts.
30	* - The code refers to 'auxiliary device' and 'mouse'; these terms are not
31	* quite interchangeable. 'Auxiliary device' is used when referring to the
32	* generic PS/2 auxiliary device interface and 'mouse' when referring to
33	* a mouse attached to the auxiliary port.
34	* - The basic modes of operation are reset, stream, and remote. Those are
35	* mutually exclusive. Stream and remote modes can additionally have wrap
36	* mode enabled.
37	* - The auxiliary device sends unsolicited data to the host only when it is
38	* both in stream mode and enabled. Otherwise it only responds to commands.
39	*
40	*
41	* There are three report packet formats supported by the emulated device. The
42	* standard three-byte PS/2 format (with middle button support), IntelliMouse
43	* four-byte format with added scroll wheel, and IntelliMouse Explorer four-byte
44	* format with reduced scroll wheel range but two additional buttons. Note that
45	* the first three bytes of the report are always the same.
46	*
47	* Upon reset, the mouse is always in the standard PS/2 mode. A special 'knock'
48	* sequence can be used to switch to ImPS/2 or ImEx mode. Three consecutive
49	* Set Sampling Rate (0F3h) commands with arguments 200, 100, 80 switch to ImPS/2
50	* mode. While in ImPS/2 or PS/2 mode, three consecutive Set Sampling Rate
51	* commands with arguments 200, 200, 80 switch to ImEx mode. The Read ID (0F2h)
52	* command will report the currently selected protocol.
53	*
54	*
55	* Standard PS/2 pointing device three-byte report packet format:
56	*
57	* +--------+--------+--------+--------+--------+--------+--------+--------+--------+
58	* \|Bit/byte\| bit 7 \| bit 6 \| bit 5 \| bit 4 \| bit 3 \| bit 2 \| bit 1 \| bit 0 \|
59	* +--------+--------+--------+--------+--------+--------+--------+--------+--------+
60	* \| Byte 1 \| Y ovfl \| X ovfl \| Y sign \| X sign \| Sync \| M btn \| R btn \| L btn \|
61	* +--------+--------+--------+--------+--------+--------+--------+--------+--------+
62	* \| Byte 2 \| X movement delta (two's complement) \|
63	* +--------+--------+--------+--------+--------+--------+--------+--------+--------+
64	* \| Byte 3 \| Y movement delta (two's complement) \|
65	* +--------+--------+--------+--------+--------+--------+--------+--------+--------+
66	*
67	* - The sync bit is always set. It allows software to synchronize data packets
68	* as the X/Y position data typically does not have bit 4 set.
69	* - The overflow bits are set if motion exceeds accumulator range. We use the
70	* maximum range (effectively 9 bits) and do not set the overflow bits.
71	* - Movement in the up/right direction is defined as having positive sign.
72	*
73	*
74	* IntelliMouse PS/2 (ImPS/2) fourth report packet byte:
75	*
76	* +--------+--------+--------+--------+--------+--------+--------+--------+--------+
77	* \|Bit/byte\| bit 7 \| bit 6 \| bit 5 \| bit 4 \| bit 3 \| bit 2 \| bit 1 \| bit 0 \|
78	* +--------+--------+--------+--------+--------+--------+--------+--------+--------+
79	* \| Byte 4 \| Z movement delta (two's complement) \|
80	* +--------+--------+--------+--------+--------+--------+--------+--------+--------+
81	*
82	* - The valid range for Z delta values is only -8/+7, i.e. 4 bits.
83	*
84	* IntelliMouse Explorer (ImEx) fourth report packet byte:
85	*
86	* +--------+--------+--------+--------+--------+--------+--------+--------+--------+
87	* \|Bit/byte\| bit 7 \| bit 6 \| bit 5 \| bit 4 \| bit 3 \| bit 2 \| bit 1 \| bit 0 \|
88	* +--------+--------+--------+--------+--------+--------+--------+--------+--------+
89	* \| Byte 4 \| 0 \| 0 \| Btn 5 \| Btn 4 \| Z mov't delta (two's complement) \|
90	* +--------+--------+--------+--------+--------+--------+--------+--------+--------+
