Reply to MIDI controller wont sync with my laptop. Please help.

Hi all,
I bought a new laptop lately to run traktor2 with a Vestax VCI 100mk2. I'm currently run windows 8, and when I plug in the controller into any of the USB ports, I get the sound that the port has been plugged into over and over, but no set up. Its like the computer is constantly trying to recognise it, but cant. I had this problem quite often with my older laptop running windows 7, but it did work eventually. The cable is fine, so there must be a problem with myself, or the hardware. Any help would be greatly appreciated. Just hoping my controller is not faulty.
