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. | |
