  32. DRIVER NOTES:
    33. 

  33. 

  34. Installation is simple, you only need to add Linux Input, Linux USB, and the 
    35. 

  35. driver to the kernel.  The driver can also be optionally built as a module.
    36. 

  36. 

  37. This driver appears to be one of possible 2 Linux USB Input Touchscreen
    38. 

  38. drivers.  Although 3M produces a binary only driver available for
    39. 

  39. download, I persist in updating this driver since I would like to use the
    40. 

  40. touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the
    41. 

  41. logical choice is to use Linux Input.
    42. 

  42. 

  43. Currently there is no way to calibrate the device via this driver.  Even if
    44. 

  44. the device could be calibrated, the driver pulls to raw coordinate data from
    45. 

  45. the controller.  This means calibration must be performed within the
    46. 

  46. userspace.
    47. 

  47. 

  48. The controller screen resolution is now 0 to 16384 for both X and Y reporting
    49. 

  49. the raw touch data.  This is the same for the old and new capacitive USB
    50. 

  50. controllers.
    51. 

  51. 

  52. Perhaps at some point an abstract function will be placed into evdev so 
    53. 

  53. generic functions like calibrations, resets, and vendor information can be 
    54. 

  54. requested from the userspace (And the drivers would handle the vendor specific
    55. 

  55. tasks).
    56. 

  56. 

  57. TODO:
    58. 

  58. 

  59. Implement a control urb again to handle requests to and from the device
    60. 

  60. such as calibration, etc once/if it becomes available.
    61. 

  61. 

  62. DISCLAIMER:
    63. 

  63. 

  64. I am not a MicroTouch/3M employee, nor have I ever been.  3M does not support 
    65. 

  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. 

  72. testing!
