- * The original descriptors of WPXXXXU tablets have three report IDs, of
- * which only two are used (8 and 9), and the remaining (7) seems to have
- * the originally intended pen description which was abandoned for some
- * reason.  From this unused description it is possible to extract the
- * actual physical extents and resolution. All the models use the same
- * descriptor with different extents for the unused report ID.
