18*4882a593Smuzhiyun * There exists an official driver on the manufacturer's website, which
19*4882a593Smuzhiyun * wasn't submitted to the kernel, for some reason. The official driver
20*4882a593Smuzhiyun * doesn't seem to support extra features of some tablets, like wheels.
21*4882a593Smuzhiyun *
22*4882a593Smuzhiyun * It shows that the feature report ID 2 could be used to control any waltop
23*4882a593Smuzhiyun * tablet input mode, switching it between "default", "tablet" and "ink".
24*4882a593Smuzhiyun *
25*4882a593Smuzhiyun * This driver only uses "default" mode for all the supported tablets. This
26*4882a593Smuzhiyun * mode tries to be HID-compatible (not very successfully), but cripples the
27*4882a593Smuzhiyun * resolution of some tablets.
28*4882a593Smuzhiyun *
29*4882a593Smuzhiyun * The "tablet" mode uses some proprietary, yet decipherable protocol, which
30*4882a593Smuzhiyun * represents the correct resolution, but is possibly HID-incompatible (i.e.
31*4882a593Smuzhiyun * indescribable by a report descriptor).
32*4882a593Smuzhiyun *
33*4882a593Smuzhiyun * The purpose of the "ink" mode is unknown.
34*4882a593Smuzhiyun *
35*4882a593Smuzhiyun * The feature reports needed for switching to each mode are these:
36*4882a593Smuzhiyun *
37*4882a593Smuzhiyun * 02 16 00 default
38*4882a593Smuzhiyun * 02 16 01 tablet
39*4882a593Smuzhiyun * 02 16 02 ink
