Hi Sonny:
Check you BIOS and make sure that nothing has been disabled with respect to this device. Usually these attach to a motherboard USB header so check under Advanced and or Peripherals for anything related to "USB". You may also want to check and confirm that both ends of the cable connection are correctly oriented and firmly in place.
Regarding a needed driver? I wouldn't expect you to need anything special but to confirm this you might want to take a look at Device Manager and see if there are any problem or "Other" devices. And if possible test your SD Card on another computer to confirm that it is not the problem.
I'm assuming that at some point this device did work? Sometimes the IC board on these devices can just go...
