46 * Original Slim Tablet 5.8 inch report descriptor. 46 * See Slim Tablet 5.8 inch description, device and HID report descriptors at
47 * 47 * http://sf.net/apps/mediawiki/digimend/?title=Waltop_Slim_Tablet_5.8%22
48 * All the reports except the report with ID 16 (the stylus) are unused,
49 * possibly because the tablet is not configured to, or because they were
50 * just copied from a more capable model. The full purpose of features
51 * described for report ID 2 is unknown.
52 *
53 * The stylus buttons are described as three bit fields, whereas actually
54 * it's an "array", i.e. they're reported as button numbers (1, 2 and 3).
55 * The "eraser" field is not used. There is also a "push" without a "pop" in
56 * the stylus description.

428 * 159 * http://sf.net/apps/mediawiki/digimend/?title=Waltop_Q_Pad
429 * There are at least two versions of this model in the wild. They are
430 * represented by Genius G-Pen M609 (older version) and Genius G-Pen M609X
431 * (newer version).
432 *
433 * Both versions have the usual pen with two barrel buttons and two
434 * identical wheels with center buttons in the top corners of the tablet
435 * base. They also have buttons on the top, between the wheels, for
436 * selecting the wheels' functions and wide/standard mode. In the wide mode
437 * the whole working surface is sensed, in the standard mode a narrower area
438 * is sensed, but the logical report extents remain the same. These modes
439 * correspond roughly to 16:9 and 4:3 aspect ratios respectively.
440 *
441 * The older version has three wheel function buttons ("scroll", "zoom" and
442 * "volume") and two separate buttons for wide and standard mode. The newer
443 * version has four wheel function buttons (plus "brush") and only one
444 * button is used for selecting wide/standard mode. So, the total number of
445 * buttons remains the same, but one of the mode buttons is repurposed as a
446 * wheels' function button in the newer version.
447 *
448 * The wheel functions are:
449 * scroll - the wheels act as scroll wheels, the center buttons switch
450 * between vertical and horizontal scrolling;
451 * zoom - the wheels zoom in/out, the buttons supposedly reset to 100%;
452 * volume - the wheels control the sound volume, the buttons mute;
453 * brush - the wheels are supposed to control brush width in a graphics
454 * editor, the buttons do nothing.
455 *
456 * Below is the newer version's report descriptor. It may very well be that
457 * the older version's descriptor is different and thus it won't be
458 * supported.
459 *
460 * The mouse report (ID 1) only uses the wheel field for reporting the tablet
461 * wheels' scroll mode. The keyboard report (ID 13) is used to report the
462 * wheels' zoom and brush control functions as key presses. The report ID 12
463 * is used to report the wheels' volume control functions. The stylus report
464 * (ID 16) has the same problems as the Slim Tablet 5.8 inch report has.
465 *
466 * The rest of the reports are unused, at least in the default configuration.
467 * The purpose of the features is unknown.

750 * There are at least two versions of this model in the wild. They are
751 * represented by Genius G-Pen M712 (older version) and Genius G-Pen M712X
752 * (newer version). The hardware difference between these versions is the same
753 * as between older and newer versions of Media Tablet 10.6 inch. The report
754 * descriptors are identical for both versions.
755 *
756 * The function, behavior and report descriptor of this tablet is similar to
757 * that of Media Tablet 10.6 inch. However, there is one more field (with
758 * Consumer AC Pan usage) in the mouse description. Then the tablet X and Y
759 * logical extents both get scaled to 0..16383 range (a hardware limit?),
760 * which kind of defeats the advertised 4000 LPI resolution, considering the
761 * physical extents of 12x7.25 inches. Plus, reports 5, 10 and 255 are used
762 * sometimes (while moving the pen) with unknown purpose. Also, the key codes
763 * generated for zoom in/out are different.
