16 * Many thanks to Oliver Kuechemann for his support.

18 * ChangeLog:
19 * v0.1 - Initial release
20 * v0.2 - Hack to get around fake event 28's. (Bryan W. Headley)
21 * v0.3 - Make URB dynamic (Bryan W. Headley, Jun-8-2002)
22 * Released to Linux 2.4.19 and 2.5.x
23 * v0.4 - Rewrote substantial portions of the code to deal with
24 * corrected control sequences, timing, dynamic configuration,
25 * support of 6000U - 12000U, procfs, and macro key support
26 * (Jan-1-2003 - Feb-5-2003, Bryan W. Headley)
27 * v1.0 - Added support for diagnostic messages, count of messages
28 * received from URB - Mar-8-2003, Bryan W. Headley
29 * v1.1 - added support for tablet resolution, changed DV and proximity
30 * some corrections - Jun-22-2003, martin schneebacher
31 * - Added support for the sysfs interface, deprecating the
32 * procfs interface for 2.5.x kernel. Also added support for
33 * Wheel command. Bryan W. Headley July-15-2003.
34 * v1.2 - Reworked jitter timer as a kernel thread.
35 * Bryan W. Headley November-28-2003/Jan-10-2004.
36 * v1.3 - Repaired issue of kernel thread going nuts on single-processor
37 * machines, introduced programmableDelay as a command line
38 * parameter. Feb 7 2004, Bryan W. Headley.
39 * v1.4 - Re-wire jitter so it does not require a thread. Courtesy of
40 * Rene van Paassen. Added reporting of physical pointer device
41 * (e.g., stylus, mouse in reports 2, 3, 4, 5. We don't know
42 * for reports 1, 6.)
43 * what physical device reports for reports 1, 6.) Also enabled
44 * MOUSE and LENS tool button modes. Renamed "rubber" to "eraser".
45 * Feb 20, 2004, Bryan W. Headley.
46 * v1.5 - Added previousJitterable, so we don't do jitter delay when the
47 * user is holding a button down for periods of time.
48 *
49 * NOTE:
50 * This kernel driver is augmented by the "Aiptek" XFree86 input
51 * driver for your X server, as well as the Gaiptek GUI Front-end
52 * "Tablet Manager".
53 * These three products are highly interactive with one another,
54 * so therefore it's easier to document them all as one subsystem.

368 * aiptek_irq can receive one of six potential reports.
369 * The documentation for each is in the body of the function.
370 *
371 * The tablet reports on several attributes per invocation of
372 * aiptek_irq. Because the Linux Input Event system allows the
373 * transmission of ONE attribute per input_report_xxx() call,
374 * collation has to be done on the other end to reconstitute
375 * a complete tablet report. Further, the number of Input Event reports
376 * submitted varies, depending on what USB report type, and circumstance.
377 * To deal with this, EV_MSC is used to indicate an 'end-of-report'
378 * message. This has been an undocumented convention understood by the kernel
379 * tablet driver and clients such as gpm and XFree86's tablet drivers.
380 *
381 * Of the information received from the tablet, the one piece I
382 * cannot transmit is the proximity bit (without resorting to an EV_MSC
383 * convention above.) I therefore have taken over REL_MISC and ABS_MISC
384 * (for relative and absolute reports, respectively) for communicating
385 * Proximity. Why two events? I thought it interesting to know if the
386 * Proximity event occurred while the tablet was in absolute or relative
387 * mode.
388 *
389 * Other tablets use the notion of a certain minimum stylus pressure
390 * to infer proximity. While that could have been done, that is yet
391 * another 'by convention' behavior, the documentation for which
392 * would be spread between two (or more) pieces of software.
393 *
394 * EV_MSC usage was terminated for this purpose in Linux 2.5.x, and
395 * replaced with the input_sync() method (which emits EV_SYN.)

2 * USB ATI Remote support
3 *
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:
16 *
17 * Feb 2004: Torrey Hoffman <thoffman@arnor.net>
18 * Version 2.2.0

20 * Version 2.2.1
21 * Added key repeat support contributed by:
22 * Vincent Vanackere <vanackere@lif.univ-mrs.fr>
23 * Added support for the "Lola" remote contributed by:

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.

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/
28 *

27 * This driver is based on:
28 * - information from http://euc.jp/periphs/xbox-controller.ja.html
29 * - the iForce driver drivers/char/joystick/iforce.c
30 * - the skeleton-driver drivers/usb/usb-skeleton.c
31 *
32 * Thanks to:
33 * - ITO Takayuki for providing essential xpad information on his website
34 * - Vojtech Pavlik - iforce driver / input subsystem
35 * - Greg Kroah-Hartman - usb-skeleton driver
36 * - XBOX Linux project - extra USB id's
37 *
38 * TODO:
39 * - fine tune axes (especially trigger axes)
40 * - fix "analog" buttons (reported as digital now)
41 * - get rumble working
42 * - need USB IDs for other dance pads
43 *
44 * History:
45 *
46 * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
47 *
48 * 2002-07-02 - 0.0.2 : basic working version
49 * - all axes and 9 of the 10 buttons work (german InterAct device)
50 * - the black button does not work
51 *
52 * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
53 * - indentation fixes
54 * - usb + input init sequence fixes
55 *
56 * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
57 * - verified the lack of HID and report descriptors
58 * - verified that ALL buttons WORK
59 * - fixed d-pad to axes mapping
60 *
61 * 2002-07-17 - 0.0.5 : simplified d-pad handling
62 *
63 * 2004-10-02 - 0.0.6 : DDR pad support
64 * - borrowed from the XBOX linux kernel
65 * - USB id's for commonly used dance pads are present
66 * - dance pads will map D-PAD to buttons, not axes
67 * - pass the module paramater 'dpad_to_buttons' to force
68 * the D-PAD to map to buttons if your pad is not detected
