Someone just gave me a control pad for my pc, the problem is that it is a 15 pin connector, and my pc hasn't got one. I've looked in my manuals and it should be next to where my speakers plug into the souncard, is there any way i can fit a 15 pin port, or is ther an adapter so i can plug it into the usb ports, any help appreciated as i havn't really got much of a clue about these things!
