/* * 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.
