| * 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 |
