XFree86 turns off the screen when using usb mouse

Hi,

I have a small problem that I'd like to solve. X automatically blanks
the screen after a while. It unblanks it if you use the keyboard or the
mouse. However it only works with serial or ps2 mice. I'm using a USB
mouse and sometimes i'll be using my computer to browse the web or play
music and suddenly the screen goes blank. It's not so serious as all I
have to do is press a button in the keyboard, but I'd still like to find
a better solution.

Thanks in advance,
Bijan
