| 32 | DRIVER NOTES: | |
| 33 | ||
| 34 | Installation is simple, you only need to add Linux Input, Linux USB, and the | |
| 35 | driver to the kernel. The driver can also be optionally built as a module. | |
| 36 | ||
| 37 | This driver appears to be one of possible 2 Linux USB Input Touchscreen | |
| 38 | drivers. Although 3M produces a binary only driver available for | |
| 39 | download, I persist in updating this driver since I would like to use the | |
| 40 | touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the | |
| 2fe0ae78 | 41 | logical choice is to use Linux Input. |

42 | |
| 43 | Currently there is no way to calibrate the device via this driver. Even if | |
| 44 | the device could be calibrated, the driver pulls to raw coordinate data from | |
| 45 | the controller. This means calibration must be performed within the | |
| 46 | userspace. | |
| 47 | ||
| 48 | The controller screen resolution is now 0 to 16384 for both X and Y reporting | |
| 49 | the raw touch data. This is the same for the old and new capacitive USB | |
| 50 | controllers. | |
| 51 | ||
| 52 | Perhaps at some point an abstract function will be placed into evdev so | |
| 53 | generic functions like calibrations, resets, and vendor information can be | |
| 54 | requested from the userspace (And the drivers would handle the vendor specific | |
| 55 | tasks). | |
| 56 | ||

57 | TODO: |
| 58 | ||
| 59 | Implement a control urb again to handle requests to and from the device | |
| 60 | such as calibration, etc once/if it becomes available. | |

| 64 | I am not a MicroTouch/3M employee, nor have I ever been. 3M does not support | |
| 65 | this driver! If you want touch drivers only supported within X, please go to: | |

| 71 | A huge thank you to 3M Touch Systems for the EXII-5010UC controllers for | |
| 72 | testing! |
