| /* |
| * 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 |

| /* |
| * 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. |

| * 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. |
