This is very true...go to the motherboard manufacturer's website and download the XP version of the USB drivers.
Wombat is right on cue as well. SP1 and later updates will install the USB drivers...in some places it will be the only way for you to get them without the original motherboard chipset driver CD as Microsoft has agreements concerning the download of USB drivers.
