Qtopia4.2:Usage of both TouchScreen and Mouse

How to use, both TouchScreen and Mouse in qtopia? I am setting QWS_MOUSE_PROTO to touchscreen device. So I am not able to use mouse.
How to set environmental variable (or how to configure) in qtopia, so that I can use both touchscreen and mouse.

Thanks & Regards,
Arun.

I tried different options and made it work.

Here is the answer:

export QWS_MOUSE_PROTO="<touchscreendriver>:<options> " will work only for TouchScreen.

export QWS_MOUSE_PROTO="Auto" works only for mouse.

so to work both TouchScreen and Mouse,

export QWS_MOUSE_PROTO="<touchscreendriver>:<options> Auto"
