0005 Changes
0006 =======
0007
0008 - 0.3 - Created based off of scanner & INSTALL from the original touchscreen
0009 driver on freecode (http://freecode.com/projects/3mtouchscreendriver)
0010 - Amended for linux-2.4.18, then 2.4.19
0011
0012 - 0.5 - Complete rewrite using Linux Input in 2.6.3
0013 Unfortunately no calibration support at this time
0014
0015 - 1.4 - Multiple changes to support the EXII 5000UC and house cleaning
0016 Changed reset from standard USB dev reset to vendor reset
0017 Changed data sent to host from compensated to raw coordinates
0018 Eliminated vendor/product module params
0019 Performed multiple successful tests with an EXII-5010UC

0040 Driver Notes
0041 ============
0042
0043 Installation is simple, you only need to add Linux Input, Linux USB, and the
0044 driver to the kernel. The driver can also be optionally built as a module.
0045
0046 This driver appears to be one of possible 2 Linux USB Input Touchscreen
0047 drivers. Although 3M produces a binary only driver available for
0048 download, I persist in updating this driver since I would like to use the
0049 touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the
0050 logical choice is to use Linux Input.
0051
0052 Currently there is no way to calibrate the device via this driver. Even if
0053 the device could be calibrated, the driver pulls to raw coordinate data from
0054 the controller. This means calibration must be performed within the
0055 userspace.
0056
0057 The controller screen resolution is now 0 to 16384 for both X and Y reporting
0058 the raw touch data. This is the same for the old and new capacitive USB
0059 controllers.
0060
0061 Perhaps at some point an abstract function will be placed into evdev so
0062 generic functions like calibrations, resets, and vendor information can be
0063 requested from the userspace (And the drivers would handle the vendor specific
0064 tasks).
0065
0066 TODO
0067 ====
0068
0069 Implement a control urb again to handle requests to and from the device
0070 such as calibration, etc once/if it becomes available.
0071
0072 Disclaimer
0073 ==========
0074
0075 I am not a MicroTouch/3M employee, nor have I ever been. 3M does not support
0076 this driver! If you want touch drivers only supported within X, please go to:

0080 Thanks

0083 A huge thank you to 3M Touch Systems for the EXII-5010UC controllers for
0084 testing!
