I just bought a Quantaray All-in-one card reader. It does not work with my Macbook OSX.

I just bought a Quantaray All-in-one card reader. My Macbook OSX does not seem to read it. I have tried attaching it with iphoto on both before and after attaching the card reader to the computer and also have tried another card. Directions say that a green light should come on to prove that connection has been made; I only get a red light. I am Europe with no help and am desperate. Can anyone out there please help? Thanks.
