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:

USB Capacitive - Pearl Case 14-205 (Discontinued)
USB Capacitive - Black Case 14-124 (Discontinued)

If it works, send me the iVendor & iProduct (or a patch) and I will add...

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).
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.
