need driver visioneer one touch scanner

I just purchased a gateway computer with Windows Xp, I have downloaded the disk that came with my visioneer onetouch 8600 scanner but my windows XP won’t recognize the scanner. I am constantly searching on the web for downloads. But I keep gettingthat “there is no driver availiable for the Window’s XP”, Can I get a download anywhere? It would be highly appreciated to find one.
Thanks
