Hi Vojtech, I'm trying to figure out what the best way to calibrate a touch screen is. I have a 3M touchscreen driven via mtouchusb, and I access it through evdev. So, I'd like to be able to initiate hardware calibration via evdev also. But I'm not sure what the best command to send through evdev would be? All I really see to talk back to the device is FF, but that doesn't seem to fit a calibration command...?
FYI, the hardware calibration sequence/command for (simple 2-point) hardware calibration of the 3M (EXII 5000UC) USB touchscreen is defined in the spec: http://www.3m.com/3MTouchSystems/downloads/tecdoc.jhtml and it's just a single USB Vendor Request. After the request the touchscreen uses the next 2 touches to do internal hardware calibration.
