35 * - Add PL models support
36 * - Fix Wacom Graphire mouse wheel again
37 * v1.21 (vp) - Removed protocol descriptions
38 * - Added MISC_SERIAL for tool serial numbers
39 * (gb) - Identify version on module load.

44 * - added smooth filter for Graphire from Peri Hankey
45 * - added PenPartner support from Olaf van Es
46 * - new tool ids from Ole Martin Bjoerndalen
47 * v1.29 (pc) - Add support for more tablets
48 * - Fix pressure reporting
49 * v1.30 (vp) - Merge 2.4 and 2.5 drivers
50 * - Since 2.5 now has input_sync(), remove MSC_SERIAL abuse
51 * - Cleanups here and there
52 * v1.30.1 (pi) - Added Graphire3 support
53 * v1.40 (pc) - Add support for several new devices, fix eraser reporting, ...
