+ *
+ * Copyright (c) 2001 Chris Atenasio <chris@crud.net>
+ * Copyright (c) 2002-2004 Bryan W. Headley <bwheadley@earthlink.net>
+ *
+ * based on wacom.c by

+ * 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.
+ * Please visit the project's "home page", located at,
+ * http://aiptektablet.sourceforge.net.

+ * To deal with this, EV_MSC is used to indicate an 'end-of-report'

+ * 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.
