Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+CHANGES
+
+- 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
+
+- 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
+
+SUPPORTED HARDWARE:
+
+        All controllers have the Vendor: 0x0596 & Product: 0x0001

+DRIVER NOTES:
+
+Installation is simple, you only need to add Linux Input, Linux USB, and the 
+driver to the kernel.  The driver can also be optionally built as a module.
+
+This driver appears to be one of possible 2 Linux USB Input Touchscreen
+drivers.  Although 3M produces a binary only driver available for
+download, I persist in updating this driver since I would like to use the
+touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the
+logical choice is to use Linux Imput.
+
+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.
+
+Perhaps at some point an abstract function will be placed into evdev so 
+generic functions like calibrations, resets, and vendor information can be 
+requested from the userspace (And the drivers would handle the vendor specific
+tasks).
+
+ADDITIONAL INFORMATION/UPDATES/X CONFIGURATION EXAMPLE:
+
+http://groomlakelabs.com/grandamp/code/microtouch/
+
+TODO:
+
+Implement a control urb again to handle requests to and from the device
+such as calibration, etc once/if it becomes available.
+
+DISCLAMER:
+
+I am not a MicroTouch/3M employee, nor have I ever been.  3M does not support 
+this driver!  If you want touch drivers only supported within X, please go to:

+
+THANKS:
+
+A huge thank you to 3M Touch Systems for the EXII-5010UC controllers for
+testing!
