| 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 |

| 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. |

| 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: |

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