[SDL] usb touch screen

[maurizio stefani]

Hi,
Thank you for the help, let me give an overview of system:
Our system is based on a geode processor and it is an embedded system (not 
shutdown allowed...), the processor performances and resosurces (Memory...) 
are not enough to host X.

We would like to use the touch screen without X environment.

The linux kernel we are using is Ubuntu 8.04 server (with no X), it seems that 
the touch screen is seen from linux as a mouse.
The coordinates we receive from the SDLgetmousestate (checkx and checky) seems 
are relative coordinates, and them are clipped into 640x480 (the touch should 
be 4096x4096).

We have no touch screen driver outside X environment (touch controller is 
PENMOUNT).


May be we are not able to set the touch system into SDL.


Thank you in advance to any people can help us.

Maurizio
