Nikolai Kondrashovcdd49a82010-08-30 14:06:38 +0400[diff] [blame]21 * There exists an official driver on the manufacturer's website, which
22 * wasn't submitted to the kernel, for some reason. The official driver
23 * doesn't seem to support extra features of some tablets, like wheels.
24 *
25 * It shows that the feature report ID 2 could be used to control any waltop
26 * tablet input mode, switching it between "default", "tablet" and "ink".
27 *
28 * This driver only uses "default" mode for all the supported tablets. This
29 * mode tries to be HID-compatible (not very successfully), but cripples the
30 * resolution of some tablets.
31 *
32 * The "tablet" mode uses some proprietary, yet decipherable protocol, which
33 * represents the correct resolution, but is possibly HID-incompatible (i.e.
34 * indescribable by a report descriptor).
35 *
36 * The purpose of the "ink" mode is unknown.
37 *
38 * The feature reports needed for switching to each mode are these:
39 *
40 * 02 16 00 default
41 * 02 16 01 tablet
42 * 02 16 02 ink
