* Native support for the Aiptek HyperPen USB Tablets |

|
* 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. |

* aiptek_irq can receive one of six potential reports. |
|
* The documentation for each is in the body of the function. |
|
* |
|
* 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. |
|
* Update: REL_MISC proved not to be such a good idea. With REL_MISC you |
|
* get an event transmitted each time. ABS_MISC works better, since it |
|
* can be set and re-set. Thus, only using ABS_MISC from now on. |
|
* |
|
* 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.) |
