Usb mass storage devices not working XP

[Pug]

As title really - bought a used lappy with xp preinstalled. The USB ports work (mouse etc) but none of mass storage devices(hdd, pen drive, sd card in card reader) work. The devices show with an ! Next to them in device manager

Any tips? IBM x31, windows xp.

sorry, which drivers? USB in general, or mass storage drivers. If the latter, any chance of a link to some?

thanks
