I have a PC running windows which has a Creative Audigy 2 ZS with an external I/O hub attached. I would love to be able to use this card on my mac mini to use my guitar and bass etc with garageband. I know the mini doesn't have PCI ports, but is there anything I can do for this? Such as a PCI-USB Adaptor or something like that. If not, is there anyway of using the I/O hub from it using just the firewire connector? Since I tried it, and OS X recognised the device, but didn't know what it was. Any help here would be appreciated.
