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
-driver to the kernel. The driver can also be optionally built as a module.
-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
-coded in, don't despair. If the driver was compiled as a module, you can
-pass options to the driver. Simply try:
+ Controller Description Part Number
+ ------------------------------------------------------
- /sbin/modprobe mtouchusb vendor=0x#### product=0x****
+ USB Capacitive - Pearl Case 14-205 (Discontinued)
+ USB Capacitive - Black Case 14-124 (Discontinued)
+ USB Capacitive - No Case 14-206 (Discontinued)
-If it works, send me the iVendor & iProduct (or a patch) and I will add...
+ USB Capacitive - Pearl Case EXII-5010UC
+ USB Capacitive - Black Case EXII-5030UC
+ USB Capacitive - No Case EXII-5050UC

+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
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.

-Currently there is no way to calibrate the device via this driver. Perhaps
-at some point an abstract function will be placed into evdev so generic
-functions like calibrations, resets, and vendor information can be requested
-(And the drivers would handle the vendor specific tasks).
-
-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.
+
+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).

TODO:
Implement a control urb again to handle requests to and from the device
-such as calibration, etc.
+such as calibration, etc once/if it becomes available.

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