32	DRIVER NOTES:
33	
34	Installation is simple, you only need to add Linux Input, Linux USB, and the 
35	driver to the kernel.  The driver can also be optionally built as a module.
36	
37	This driver appears to be one of possible 2 Linux USB Input Touchscreen
38	drivers.  Although 3M produces a binary only driver available for
39	download, I persist in updating this driver since I would like to use the
40	touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the
41	logical choice is to use Linux Input.
42	
43	Currently there is no way to calibrate the device via this driver.  Even if
44	the device could be calibrated, the driver pulls to raw coordinate data from
45	the controller.  This means calibration must be performed within the
46	userspace.
47	
48	The controller screen resolution is now 0 to 16384 for both X and Y reporting
49	the raw touch data.  This is the same for the old and new capacitive USB
50	controllers.
51	
52	Perhaps at some point an abstract function will be placed into evdev so 
53	generic functions like calibrations, resets, and vendor information can be 
54	requested from the userspace (And the drivers would handle the vendor specific
55	tasks).
56	
57	TODO:
58	
59	Implement a control urb again to handle requests to and from the device
60	such as calibration, etc once/if it becomes available.
61	
62	DISCLAIMER:
63	
64	I am not a MicroTouch/3M employee, nor have I ever been.  3M does not support 
65	this driver!  If you want touch drivers only supported within X, please go to:

68	
69	THANKS:
70	
71	A huge thank you to 3M Touch Systems for the EXII-5010UC controllers for
72	testing!
