Check in Device Manager under USB Controllers to see if you have a USB2 Enhanced Host Controller rather than just a Universal Host Controller. Do you know what make your carder reader is ? It will probably be listed under disk drives in Device Manager. You can then check for updated drivers.
If device manager does not report Enhanced Host Controller as per Zepppelyn, then you do not have a USB setup despite what the label on the card reader states ! The simplest way to sort this out is to buy a USB2 pci card ( around £10 or less )as citadel suggested and then buy a cheap card reader unless you know your way around the inside of your pc and can reinstall the card reader into the socket on the pci card.
