| CHANGES | |
| - 0.3 - Created based off of scanner & INSTALL from the original touchscreen | |
| driver on freecode (http://freecode.com/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 successful 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 Input. | |
| 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 once/if it becomes available. | |
| DISCLAIMER: | |
| 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! |
