* Complete rewrite using Linux Input in 2.6.3
* Unfortunately no calibration support at this time
*
+ * 1.4 04/25/2004 (TEJ) tejohnson@yahoo.com
+ * Changed reset from standard USB dev reset to vendor reset
+ * Changed data sent to host from compensated to raw coordinates
+ * Eliminated vendor/product module params
+ * Performed multiple successfull tests with an EXII-5010UC
+ *
