  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).

  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!
