/*
* 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
