I;d expect this to work with the standard usb driver. The dpi is adjusted from beneath ((1600 dpi--blue; 3200 dpi--purple; 5000 dpi--red) and weights inserted from the box - purely mechanical. If it is not operational, my guess would be a problem with the usb lead or with the standard usb drivers of your machine. Check for this latter with any other usb connected item that should be usable from the same port. If repairing the usb lead itself replace it with a cheap usb lead; these are obtainable in most stores now, including supermarkets, and replacement will be easier than an attempt at repair.
