 CHANGES
 
-- Created based off of scanner & INSTALL from the original touchscreen
+- 0.3 - Created based off of scanner & INSTALL from the original touchscreen
   driver on freshmeat (http://freshmeat.net/projects/3mtouchscreendriver)
 - Amended for linux-2.4.18, then 2.4.19
 
-- Complete rewrite using Linux Input in 2.6.3
+- 0.5 - Complete rewrite using Linux Input in 2.6.3
    Unfortunately no calibration support at this time
 
+- 1.4 - Multiple changes to support the EXII 5000UC and house cleaning
+   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
 
-DRIVER NOTES:
+SUPPORTED HARDWARE:

+        All controllers have the Vendor: 0x0596 & Product: 0x0001
 
-Installation is simple, you only need to add Linux Input, Linux USB, and the

-If you have another MicroTouch device that you wish to experiment with
-or try using this driver with, but the Vendor and Product ID's are not

-pass options to the driver.  Simply try:

 touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the
 logical choice is to use Linux Imput.
 
-A little info about the MicroTouch USB controller (14-206):
-
-Y is inverted, and the device has a total possible resolution of 0 - 65535.
-
-Y is inverted by the driver by:
-
-        input.absmin[ABS_Y] =  MTOUCHUSB_MAX_YC;
-        input.absmax[ABS_Y] =  MTOUCHUSB_MIN_YC;
-
-absmin & absmax are also used to scale the data, sine it is rather high 
-resolution.

-ADDITIONAL INFORMATION/UPDATES:
+Currently there is no way to calibrate the device via this driver.  Even if
+the device could be calibrated, the driver pulls to raw coordinate data from
+the controller.  This means calibration must be performed within the
+userspace.
+
+The controller screen resolution is now 0 to 16384 for both X and Y reporting
+the raw touch data.  This is the same for the old and new capacitive USB
+controllers.
