The first thing you want to do is check out what model you have. If you have one of the older ones it should be a logitech, if you have the newer silver one it should be a namtai. You can also check this by checking your device manager via the control panel, it should designate it as either a logitech or namtai. Next what you want to do is go to this website: http://search.4shared.com/q/1/eyetoy
