- *
- * 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
