/*

* There exists an official driver on the manufacturer's website, which
|
|
* wasn't submitted to the kernel, for some reason. The official driver
|
|
* doesn't seem to support extra features of some tablets, like wheels.
|
|
*
|
|
* It shows that the feature report ID 2 could be used to control any waltop
|
|
* tablet input mode, switching it between "default", "tablet" and "ink".
|
|
*
|
|
* This driver only uses "default" mode for all the supported tablets. This
|
|
* mode tries to be HID-compatible (not very successfully), but cripples the
|
|
* resolution of some tablets.
|
|
*
|
|
* 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.
|
|
*
|
|
* The feature reports needed for switching to each mode are these:
|
|
*
|
|
* 02 16 00 default
|
|
* 02 16 01 tablet
|
|
* 02 16 02 ink

* All the reports except the report with ID 16 (the stylus) are unused,

|
|
* 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.
