Abit KD7:Can't Install USB 2 Drivers

I have Windows XP Professional on an Abit KD7 machine. I'm trying to install
the USB 2 drivers but it won't take because it INSISTS on asking me to
install the Windows XP SP1 update.

For whatever reason I can't get the XP SP1 update to install (the
executable) although I do have the "XP Hotfix {SP1}" updates installed via
automatic updating procedures.

Is there anyway around this, or am I stuck?
