Looks like it may be a hardware compatibility issue--Old hardware. Make sure your BIOS is up to date. You could also try and unplug the card reader from the USB header, reboot, shutdown then plug it back in. See if Windows will recognize new hardware after a reboot. Other than that, about all I can suggest is to try and identify the card reader then see if the manufacturer has drivers for Windows 7 (but I doubt it). Last and probably the best, a newer card reader can be had for less than $30.
One other thing, do you have a USB port on the card reader? if you plug a USB thumb drive into it, does Windows recognize that?
