+ * - Vojtech Pavlik - iforce driver / input subsystem
+ * - Greg Kroah-Hartman - usb-skeleton driver
+ * - XBOX Linux project - extra USB id's
+ *
+ * TODO:
+ * - fine tune axes (especially trigger axes)
+ * - fix "analog" buttons (reported as digital now)
+ * - get rumble working
+ * - need USB IDs for other dance pads
+ *
+ * History:
+ *
+ * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
+ *
+ * 2002-07-02 - 0.0.2 : basic working version
+ * - all axes and 9 of the 10 buttons work (german InterAct device)
+ * - the black button does not work
+ *
+ * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
+ * - indentation fixes
+ * - usb + input init sequence fixes
+ *
+ * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
+ * - verified the lack of HID and report descriptors
+ * - verified that ALL buttons WORK
+ * - fixed d-pad to axes mapping
+ *
+ * 2002-07-17 - 0.0.5 : simplified d-pad handling
+ *
+ * 2004-10-02 - 0.0.6 : DDR pad support
+ * - borrowed from the XBOX linux kernel
+ * - USB id's for commonly used dance pads are present
+ * - dance pads will map D-PAD to buttons, not axes
+ * - pass the module paramater 'dpad_to_buttons' to force
+ * the D-PAD to map to buttons if your pad is not detected

+ * USB ATI Remote support
+ *
+ * Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net>
+ * Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
+ *
+ * This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
+ * porting to the 2.6 kernel interfaces, along with other modification
+ * to better match the style of the existing usb/input drivers. However, the
+ * protocol and hardware handling is essentially unchanged from 2.1.1.
+ *
+ * The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
+ * Vojtech Pavlik.
+ *
+ * Changes:
+ *
+ * Feb 2004: Torrey Hoffman <thoffman@arnor.net>
+ * Version 2.2.0
+ * Jun 2004: Torrey Hoffman <thoffman@arnor.net>
+ * Version 2.2.1
+ * Added key repeat support contributed by:
+ * Vincent Vanackere <vanackere@lif.univ-mrs.fr>
+ * Added support for the "Lola" remote contributed by:
+ * Seth Cohn <sethcohn@yahoo.com>

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

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

+ * Native support for the Aiptek HyperPen USB Tablets
+ * (4000U/5000U/6000U/8000U/12000U)
+ *
+ * Copyright (c) 2001 Chris Atenasio <chris@crud.net>
+ * Copyright (c) 2002-2004 Bryan W. Headley <bwheadley@earthlink.net>
+ *
+ * based on wacom.c by
+ * Vojtech Pavlik <vojtech@suse.cz>
+ * Andreas Bach Aaen <abach@stofanet.dk>
+ * Clifford Wolf <clifford@clifford.at>
+ * Sam Mosel <sam.mosel@computer.org>
+ * James E. Blair <corvus@gnu.org>
+ * Daniel Egger <egger@suse.de>
+ *
+ * Many thanks to Oliver Kuechemann for his support.
+ *
+ * ChangeLog:
+ * v0.1 - Initial release
+ * v0.2 - Hack to get around fake event 28's. (Bryan W. Headley)
+ * v0.3 - Make URB dynamic (Bryan W. Headley, Jun-8-2002)
+ * Released to Linux 2.4.19 and 2.5.x
+ * v0.4 - Rewrote substantial portions of the code to deal with
+ * corrected control sequences, timing, dynamic configuration,
+ * support of 6000U - 12000U, procfs, and macro key support
+ * (Jan-1-2003 - Feb-5-2003, Bryan W. Headley)
+ * v1.0 - Added support for diagnostic messages, count of messages
+ * received from URB - Mar-8-2003, Bryan W. Headley
+ * v1.1 - added support for tablet resolution, changed DV and proximity
+ * some corrections - Jun-22-2003, martin schneebacher
+ * - Added support for the sysfs interface, deprecating the
+ * procfs interface for 2.5.x kernel. Also added support for
+ * Wheel command. Bryan W. Headley July-15-2003.
+ * v1.2 - Reworked jitter timer as a kernel thread.
+ * Bryan W. Headley November-28-2003/Jan-10-2004.
+ * v1.3 - Repaired issue of kernel thread going nuts on single-processor
+ * machines, introduced programmableDelay as a command line
+ * parameter. Feb 7 2004, Bryan W. Headley.
+ * v1.4 - Re-wire jitter so it does not require a thread. Courtesy of
+ * Rene van Paassen. Added reporting of physical pointer device
+ * (e.g., stylus, mouse in reports 2, 3, 4, 5. We don't know
+ * for reports 1, 6.)
+ * what physical device reports for reports 1, 6.) Also enabled
+ * MOUSE and LENS tool button modes. Renamed "rubber" to "eraser".
+ * Feb 20, 2004, Bryan W. Headley.
+ * v1.5 - Added previousJitterable, so we don't do jitter delay when the
+ * user is holding a button down for periods of time.
+ *
+ * NOTE:
+ * This kernel driver is augmented by the "Aiptek" XFree86 input
+ * driver for your X server, as well as the Gaiptek GUI Front-end
+ * "Tablet Manager".
+ * These three products are highly interactive with one another,
+ * so therefore it's easier to document them all as one subsystem.

+ * aiptek_irq can receive one of six potential reports.

+ * The tablet reports on several attributes per invocation of

+ * transmission of ONE attribute per input_report_xxx() call,
+ * collation has to be done on the other end to reconstitute
+ * a complete tablet report. Further, the number of Input Event reports
+ * submitted varies, depending on what USB report type, and circumstance.
+ * To deal with this, EV_MSC is used to indicate an 'end-of-report'
+ * message. This has been an undocumented convention understood by the kernel
+ * tablet driver and clients such as gpm and XFree86's tablet drivers.
+ *
+ * Of the information received from the tablet, the one piece I
+ * cannot transmit is the proximity bit (without resorting to an EV_MSC
+ * convention above.) I therefore have taken over REL_MISC and ABS_MISC
+ * (for relative and absolute reports, respectively) for communicating
+ * Proximity. Why two events? I thought it interesting to know if the
+ * Proximity event occurred while the tablet was in absolute or relative
+ * mode.
+ *
+ * Other tablets use the notion of a certain minimum stylus pressure
+ * to infer proximity. While that could have been done, that is yet
+ * another 'by convention' behavior, the documentation for which
+ * would be spread between two (or more) pieces of software.
