- *
- * It has meant that I've been able to correct my interpretation of the

- * CC -- 2003/9/29
- *
- * History
- * 1.0 & 1.1  2003 (CC) vojtech@suse.cz
- *   Original version for 2.4.x kernels
- *
- * 1.2  02/03/2005 (HCE) hc@mivu.no
- *   Complete rewrite to support Linux 2.6.10, thanks to mtouchusb.c for hints.
- *   Unfortunately no calibration support at this time.
- *
- * 1.2.1  09/03/2005 (HCE) hc@mivu.no
- *   Code cleanup and adjusting syntax to start matching kernel standards
- * 
- * 1.2.2  10/05/2006 (MJA) massad@gmail.com
- *   Flag for detecting if the screen was being touch was incorrectly 
- *   inverted, so no touch events were being detected.

- *  (http://freshmeat.net/projects/3mtouchscreendriver)
- *
- * 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
