4 * Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net>
5 * Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
6 *
7 * This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
8 * porting to the 2.6 kernel interfaces, along with other modification
9 * to better match the style of the existing usb/input drivers. However, the
10 * protocol and hardware handling is essentially unchanged from 2.1.1.
11 *
12 * The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
13 * Vojtech Pavlik.
14 *
15 * Changes:

44 * Hardware & software notes
45 *
46 * These remote controls are distributed by ATI as part of their
47 * "All-In-Wonder" video card packages. The receiver self-identifies as a
48 * "USB Receiver" with manufacturer "X10 Wireless Technology Inc".
49 *
50 * The "Lola" remote is available from X10. See:
51 * http://www.x10.com/products/lola_sg1.htm
52 * The Lola is similar to the ATI remote but has no mouse support, and slightly
53 * different keys.
54 *
55 * It is possible to use multiple receivers and remotes on multiple computers
56 * simultaneously by configuring them to use specific channels.
57 *
58 * The RF protocol used by the remote supports 16 distinct channels, 1 to 16.
59 * Actually, it may even support more, at least in some revisions of the
60 * hardware.
61 *
62 * Each remote can be configured to transmit on one channel as follows:
63 * - Press and hold the "hand icon" button.
64 * - When the red LED starts to blink, let go of the "hand icon" button.
65 * - When it stops blinking, input the channel code as two digits, from 01
66 * to 16, and press the hand icon again.
67 *
68 * The timing can be a little tricky. Try loading the module with debug=1
69 * to have the kernel print out messages about the remote control number
70 * and mask. Note: debugging prints remote numbers as zero-based hexadecimal.
71 *
72 * The driver has a "channel_mask" parameter. This bitmask specifies which
73 * channels will be ignored by the module. To mask out channels, just add
74 * all the 2^channel_number values together.
75 *
76 * For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote
77 * ignore signals coming from remote controls transmitting on channel 4, but
78 * accept all other channels.
79 *
80 * Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be
81 * ignored.
82 *
83 * The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this
84 * parameter are unused.
85 *

1/*
2 * A driver for the Griffin Technology, Inc. "PowerMate" USB controller dial.
3 *
4 * v1.1, (c)2002 William R Sowerbutts <will@sowerbutts.com>
5 *
6 * This device is a anodised aluminium knob which connects over USB. It can measure
7 * clockwise and anticlockwise rotation. The dial also acts as a pushbutton with
8 * a spring for automatic release. The base contains a pair of LEDs which illuminate
9 * the translucent base. It rotates without limit and reports its relative rotation
10 * back to the host when polled by the USB controller.
11 *
12 * Testing with the knob I have has shown that it measures approximately 94 "clicks"
13 * for one full rotation. Testing with my High Speed Rotation Actuator (ok, it was
14 * a variable speed cordless electric drill) has shown that the device can measure
15 * speeds of up to 7 clicks either clockwise or anticlockwise between pollings from
16 * the host. If it counts more than 7 clicks before it is polled, it will wrap back
17 * to zero and start counting again. This was at quite high speed, however, almost
18 * certainly faster than the human hand could turn it. Griffin say that it loses a
19 * pulse or two on a direction change; the granularity is so fine that I never
20 * noticed this in practice.
21 *
22 * The device's microcontroller can be programmed to set the LED to either a constant
23 * intensity, or to a rhythmic pulsing. Several patterns and speeds are available.
24 *
25 * Griffin were very happy to provide documentation and free hardware for development.
26 *
27 * Some userspace tools are available on the web: http://sowerbutts.com/powermate/

21 * Description:
22 * Driver for the USB-P1K voip usb phone.
23 * This device is produced by Yealink Network Technology Co Ltd
24 * but may be branded under several names:
25 * - Yealink usb-p1k
26 * - Tiptel 115
27 * - ...
28 *
29 * This driver is based on:
30 * - the usbb2k-api http://savannah.nongnu.org/projects/usbb2k-api/
31 * - information from http://memeteau.free.fr/usbb2k
32 * - the xpad-driver drivers/input/joystick/xpad.c
33 *
34 * Thanks to:
35 * - Olivier Vandorpe, for providing the usbb2k-api.
36 * - Martin Diehl, for spotting my memory allocation bug.
37 *
38 * History:
39 * 20050527 henk First version, functional keyboard. Keyboard events
40 * will pop-up on the ../input/eventX bus.
41 * 20050531 henk Added led, LCD, dialtone and sysfs interface.
42 * 20050610 henk Cleanups, make it ready for public consumption.
43 * 20050630 henk Cleanups, fixes in response to comments.
44 * 20050701 henk sysfs write serialisation, fix potential unload races
45 * 20050801 henk Added ringtone, restructure USB
46 * 20050816 henk Merge 2.6.13-rc6
