+ * Original Media Tablet 14.1 inch report descriptor.
+ *
+ * There are at least two versions of this model in the wild. They are
+ * represented by Genius G-Pen M712 (older version) and Genius G-Pen M712X
+ * (newer version). The hardware difference between these versions is the same
+ * as between older and newer versions of Media Tablet 10.6 inch. The report
+ * descriptors are identical for both versions.
+ *
+ * The function, behavior and report descriptor of this tablet is similar to
+ * that of Media Tablet 10.6 inch. However, there is one more field (with
+ * Consumer AC Pan usage) in the mouse description. Then the tablet X and Y
+ * logical extents both get scaled to 0..16383 range (a hardware limit?),
+ * which kind of defeats the advertised 4000 LPI resolution, considering the
+ * physical extents of 12x7.25 inches. Plus, reports 5, 10 and 255 are used
+ * sometimes (while moving the pen) with unknown purpose. Also, the key codes
+ * generated for zoom in/out are different.
