Hello,

I have a touch screen that use usbtouchscreen.c driver from kernel (CONFIG_TOUCHSCREEN_USB_GENERAL_TOUCH).

Well, I would like to use this touch with QT and TSLIB, but TSLIB need a event, ABS_PRESSURE, but in this moment, kernel driver do not report this event.

Support events types:
Event type 0x00: unknown
Event type 0x01: Keys or buttons
Event type 0x03: Absolute axis

Absolute Axis:
Absolute axis 0x00: X axis
Absolute axis 0x01: Y axis

My idea is to make a trick and modified driver to report this event, but I do not known where can I do it.

I have checked usbtouchscreen.c in /drivers/input/touchscreen but I do not find anything.

any advice??

Best regards
