Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

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!
