| * USB Wacom Graphire and Wacom Intuos tablet support |
| * |
| * Sponsored by SuSE |
| * |
| * ChangeLog: |
| * v0.1 (vp) - Initial release |
| * v0.2 (aba) - Support for all buttons / combinations |
| * v0.3 (vp) - Support for Intuos added |
| * v0.4 (sm) - Support for more Intuos models, menustrip |
| * relative mode, proximity. |
| * v0.5 (vp) - Big cleanup, nifty features removed, |
| * they belong in userspace |
| * v1.8 (vp) - Submit URB only when operating, moved to CVS, |
| * use input_report_key instead of report_btn and |
| * other cleanups |
| * v1.11 (vp) - Add URB ->dev setting for new kernels |
| * v1.11 (jb) - Add support for the 4D Mouse & Lens |
| * v1.12 (de) - Add support for two more inking pen IDs |
| * v1.14 (vp) - Use new USB device id probing scheme. |
| * Fix Wacom Graphire mouse wheel |
| * v1.18 (vp) - Fix mouse wheel direction |
| * Make mouse relative |
| * v1.20 (fl) - Report tool id for Intuos devices |
| * - Multi tools support |
| * - Corrected Intuos protocol decoding (airbrush, 4D mouse, lens cursor...) |
| * - Add PL models support |
| * - Fix Wacom Graphire mouse wheel again |
| * v1.21 (vp) - Removed protocol descriptions |
| * - Added MISC_SERIAL for tool serial numbers |
| * (gb) - Identify version on module load. |
