NEC XG 628 USB 3.0 Express Card

I am trying to use this express card in my Toshiba L355-s7915. I downloaded the latest driver from the Renesas site and installed. When I insert the card, the computer gives an audible signal and info shows in the toolbar to “safely remove”. However, the external hard drive I am trying to use does not show up in the “drives listing”. What can I do to fix this?
