The attached patch for the 3M Touch Systems Capacitive controller.

Quick list of changes:

        *    Changed reset from standard USB dev reset to vendor reset
        *    Changed data sent to host from compensated to raw coordinates
        *    Eliminated vendor/product module params
        *    Performed multiple successfull tests with an EXII-5010UC

The changes are primarily due to comments from Vojtech Pavlik, as well
as making the newer EXII-50XXUC controllers work.

Thanks to 3M Touch Systems for sending me some new controllers to test with!
