- *  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
- * aiptek_irq. Because the Linux Input Event system allows the
- * 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.
- *
- * EV_MSC usage was terminated for this purpose in Linux 2.5.x, and
- * replaced with the input_sync() method (which emits EV_SYN.)
