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