| 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! |
