+ *
+ * This driver only uses "default" mode for all the supported tablets. This

+ *
+ * The "tablet" mode uses some proprietary, yet decipherable protocol, which
+ * represents the correct resolution, but is possibly HID-incompatible (i.e.
+ * indescribable by a report descriptor).
+ *
+ * The purpose of the "ink" mode is unknown.

+ * Original Media Tablet 10.6 inch report descriptor.
+ *
+ * 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.

+ * There are at least two versions of this model in the wild. They are

+ * (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.
