| * the originally intended pen description which was abandoned for some |

| * Original PF1209 report descriptor. |

| * The descriptor is similar to WPXXXXU descriptors, with an addition of a |
| * feature report (ID 4) of unknown purpose. |
| * |
| * Although the advertised resolution is 4000 LPI the unused report ID |
| * (taken from WPXXXXU, it seems) states 2000 LPI, but it is probably |
| * incorrect and is a result of blind copying without understanding. Anyway |
| * the real logical extents are always scaled to 0..32767, which IMHO spoils |
