Open Question: Does anyone know how to get a ps2 to usb adapter working on a pc?

The adaptor i have is PantherLord Pc-Usb convertor (Windows XP Home) [USB] pt-usb030, its meant to be plug and play !!! It installs the hardware ok and i downloaded the driver for it from the pantherlord website but the only thing that works on the controllers is the vibration and the analogue light, i have also tried calibrating it going through control panel but it still doesnt work I emailed the websites support email but have had no reply since i sent it last week, so i am trying to find solutions through here hopefully someone can help :(
