I am thinking no because the usb needs to load up some sort of drivers and the older mouse wont have those programed. Cant hurt to try i guess but a usb mouse can be had for like $10 for a decent logitech optical. So why not just spend $10
ipod chargers and xbox controllers use USB, even though they have different cables. PS/2 isn't the same system. The adapter you need is only an inocuous little pin-changer, so it may be possible, but I can't guarantee it. No harm in trying I suppose.
