Precision M6500 8-in-1 Card Reader

I have a Precision M6500 laptop which has recently been formated and rebuilt with all original drivers, however my 8-in-1 Card Reader doesn't seem to be working and won't recognize an SD Card when inserted.

I've looked on the Driver Download page to see if there is a driver for the Card Reader that I am missing but can not make heads or tail of it.

Does anyone have any suggestions?
