- *
- * History
- *
- * 0.3 & 0.4 2002 (TEJ) tejohnson@yahoo.com
- * Updated to 2.4.18, then 2.4.19
- * Old version still relied on stealing a minor
- *
- * 0.5 02/26/2004 (TEJ) tejohnson@yahoo.com
- * 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 successful tests with an EXII-5010UC
- *
- * 1.5 02/27/2005 ddstreet@ieee.org
- * Added module parameter to select raw or hw-calibrated coordinate reporting
