Sounds to me like you may have a much older PC (packard Bell) and you installed XP on that PC which previously had win95 (maybe it still does and you just did an upgrade install?) on it and it failed to correctly install the USB drivers. In this case you need to find out exactly what chipset/motherboard the PC is using and you may have to install a win2000 (xp compatible driver) manually. EG; Winxp isn't recognizing your USB ports correctly on your older PC.
