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.
