21 | * Original Slim Tablet 5.8 inch report descriptor. | |
22 | * | |
23 | * All the reports except the report with ID 16 (the stylus) are unused, | |
24 | * possibly because the tablet is not configured to, or because they were | |
25 | * just copied from a more capable model. The purpose of features described | |
26 | * for report ID 2 is unknown. | |
27 | * | |
28 | * The stylus buttons are described as three bit fields, whereas actually | |
29 | * it's an "array", i.e. they're reported as button numbers (1, 2 and 3). | |
30 | * The "eraser" field is not used. There is also a "push" without a "pop" in | |
31 | * the stylus description. | |

202 | * Original Media Tablet 10.6 inch report descriptor. | |
203 | * | |
204 | * There are at least two versions of this model in the wild. They are | |
205 | * represented by Genius G-Pen M609 (older version) and Genius G-Pen M609X | |
206 | * (newer version). | |
207 | * | |
208 | * Both versions have the usual pen with two barrel buttons and two | |
209 | * identical wheels with center buttons in the top corners of the tablet | |
210 | * base. They also have buttons on the top, between the wheels, for | |
211 | * selecting the wheels' functions and wide/standard mode. In the wide mode | |
212 | * the whole working surface is sensed, in the standard mode a narrower area | |
213 | * is sensed, but the logical report extents remain the same. These modes | |
214 | * correspond roughly to 16:9 and 4:3 aspect ratios respectively. | |
215 | * | |
216 | * The older version has three wheel function buttons ("scroll", "zoom" and | |
217 | * "volume") and two separate buttons for wide and standard mode. The newer | |
218 | * version has four wheel function buttons (plus "brush") and only one | |
219 | * button is used for selecting wide/standard mode. So, the total number of | |
220 | * buttons remains the same, but one of the mode buttons is repurposed as a | |
221 | * wheels' function button in the newer version. | |
222 | * | |
223 | * The wheel functions are: | |
4b5b4575 NK |
224 | * scroll - the wheels act as scroll wheels, the center buttons switch |
225 | * between vertical and horizontal scrolling; | |
226 | * zoom - the wheels zoom in/out, the buttons supposedly reset to 100%; | |
227 | * volume - the wheels control the sound volume, the buttons mute; | |
72a46344 NK |
228 | * brush - the wheels are supposed to control brush width in a graphics |
229 | * editor, the buttons do nothing. | |
230 | * | |
231 | * Below is the newer version's report descriptor. It may very well be that | |
232 | * the older version's descriptor is different and thus it won't be | |
233 | * supported. | |
234 | * | |
235 | * The mouse report (ID 1) only uses the wheel field for reporting the tablet | |
236 | * wheels' scroll mode. The keyboard report (ID 13) is used to report the | |
237 | * wheels' zoom and brush control functions as key presses. The report ID 12 | |
238 | * is used to report the wheels' volume control functions. The stylus report | |
239 | * (ID 16) has the same problems as the Slim Tablet 5.8 inch report has. | |
240 | * | |
241 | * The rest of the reports are unused, at least in the default configuration. | |
242 | * The purpose of the features is unknown. | |

514 | * Original Media Tablet 14.1 inch report descriptor. | |
515 | * | |
516 | * There are at least two versions of this model in the wild. They are | |
517 | * represented by Genius G-Pen M712 (older version) and Genius G-Pen M712X | |
518 | * (newer version). The hardware difference between these versions is the same | |
519 | * as between older and newer versions of Media Tablet 10.6 inch. The report | |
520 | * descriptors are identical for both versions. | |
521 | * | |
522 | * The function, behavior and report descriptor of this tablet is similar to | |
523 | * that of Media Tablet 10.6 inch. However, there is one more field (with | |
524 | * Consumer AC Pan usage) in the mouse description. Then the tablet X and Y | |
525 | * logical extents both get scaled to 0..16383 range (a hardware limit?), | |
526 | * which kind of defeats the advertised 4000 LPI resolution, considering the | |
527 | * physical extents of 12x7.25 inches. Plus, reports 5, 10 and 255 are used | |
528 | * sometimes (while moving the pen) with unknown purpose. Also, the key codes | |
529 | * generated for zoom in/out are different. | |
