- * Original Slim Tablet 5.8 inch report descriptor.
- *
- * All the reports except the report with ID 16 (the stylus) are unused,
- * possibly because the tablet is not configured to, or because they were
- * just copied from a more capable model. The full purpose of features
- * described for report ID 2 is unknown.
- *
- * The stylus buttons are described as three bit fields, whereas actually
- * it's an "array", i.e. they're reported as button numbers (1, 2 and 3).
- * The "eraser" field is not used. There is also a "push" without a "pop" in
- * the stylus description.

- * There are at least two versions of this model in the wild. They are
- * represented by Genius G-Pen M609 (older version) and Genius G-Pen M609X
- * (newer version).
- *
- * Both versions have the usual pen with two barrel buttons and two
- * identical wheels with center buttons in the top corners of the tablet
- * base. They also have buttons on the top, between the wheels, for
- * selecting the wheels' functions and wide/standard mode. In the wide mode
- * the whole working surface is sensed, in the standard mode a narrower area
- * is sensed, but the logical report extents remain the same. These modes
- * correspond roughly to 16:9 and 4:3 aspect ratios respectively.
- *
- * The older version has three wheel function buttons ("scroll", "zoom" and
- * "volume") and two separate buttons for wide and standard mode. The newer
- * version has four wheel function buttons (plus "brush") and only one
- * button is used for selecting wide/standard mode. So, the total number of
- * buttons remains the same, but one of the mode buttons is repurposed as a
- * wheels' function button in the newer version.
- *
- * The wheel functions are:
- * scroll - the wheels act as scroll wheels, the center buttons switch
- * between vertical and horizontal scrolling;
- * zoom - the wheels zoom in/out, the buttons supposedly reset to 100%;
- * volume - the wheels control the sound volume, the buttons mute;
- * brush - the wheels are supposed to control brush width in a graphics
- * editor, the buttons do nothing.
- *
- * Below is the newer version's report descriptor. It may very well be that
- * the older version's descriptor is different and thus it won't be
- * supported.
- *
- * The mouse report (ID 1) only uses the wheel field for reporting the tablet
- * wheels' scroll mode. The keyboard report (ID 13) is used to report the
- * wheels' zoom and brush control functions as key presses. The report ID 12
- * is used to report the wheels' volume control functions. The stylus report
- * (ID 16) has the same problems as the Slim Tablet 5.8 inch report has.
- *
- * The rest of the reports are unused, at least in the default configuration.
- * The purpose of the features is unknown.

- * Original Media Tablet 14.1 inch report descriptor.
- *
- * There are at least two versions of this model in the wild. They are
- * represented by Genius G-Pen M712 (older version) and Genius G-Pen M712X
- * (newer version). The hardware difference between these versions is the same
- * as between older and newer versions of Media Tablet 10.6 inch. The report
- * descriptors are identical for both versions.
- *
- * The function, behavior and report descriptor of this tablet is similar to
- * that of Media Tablet 10.6 inch. However, there is one more field (with
- * Consumer AC Pan usage) in the mouse description. Then the tablet X and Y
- * logical extents both get scaled to 0..16383 range (a hardware limit?),
- * which kind of defeats the advertised 4000 LPI resolution, considering the
- * physical extents of 12x7.25 inches. Plus, reports 5, 10 and 255 are used
- * sometimes (while moving the pen) with unknown purpose. Also, the key codes
- * generated for zoom in/out are different.
