Subject: HID-Multitouch: eGalax Touchscreen Pressure

Hello everybody
After I finally got the touchscreen to work thanks to Benjamin, there
remains one little issue for the eGalax 0eef:a001
I'm pretty sure one could measure the pressure by which the finger(s)
touches the screeen. Currently, even coming close to the surface is
taken as a touch land. Here is the rdesc. If it is does not report such
a capability, then something is wrong, I think. I cannot recall having
had such overly responsive behaviour under windows.
How to add support for finger-pressure?
Cedric
