- * 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.
