Topic: Gamecube Gameshark Memory card Help?

Hello, I have a Gameshark Gamecube Memory card that I had been given to by a relative who had been long gone living someplace else. All that was there was a cord with USB connectivity and the other connecting to the memory card. I found an image that looks exactly like mine here: http://i.ebayimg.com/00/s/NzY4WDEwMjQ=/z/WGMAAOSwuMFUbq0d/$_3... . My first thought when I received it was that you could transfer Gamecube saves to the Memory card via Computer, so I got out my Laptop and plugged It in and I realized I would most likely have the same problem I would with a past Datel product, The Action Replay DSI. You were required to update the Driver with the .INF file on the disk. There is my problem: I never got a disk with it so what can I do with it now? Thank You for Your Time.
