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 | ||
41 | logical choice is to use Linux Imput. | ||
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 | ADDITIONAL INFORMATION/UPDATES/X CONFIGURATION EXAMPLE: | ||

60 | |||
61 | TODO: | ||
62 | |||
63 | Implement a control urb again to handle requests to and from the device | ||
64 | such as calibration, etc once/if it becomes available. | ||
65 | |||
66 | DISCLAMER: | ||
67 | |||
68 | I am not a MicroTouch/3M employee, nor have I ever been. 3M does not support | ||
69 | this driver! If you want touch drivers only supported within X, please go to: | ||

73 | THANKS: | ||
74 | |||
75 | A huge thank you to 3M Touch Systems for the EXII-5010UC controllers for | ||
76 | testing! | ||
