m-Audio USB MIDIsport 2x2 MIDI Interface and macbook pro

i just got a m-Audio USB MIDIsport 2x2 MIDI Interface on ebay, but I can not find drivers so that it will be able to run on my macbook pro (which is obviosly Intel).However, there is one driver that can support it but its for firewire, which dose not make any sence because it is a usb controler.

here is a link to the driver list
