+ * 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
+ * the precision.
