I have a corsair 400r case which has a firewire port and an Asrock z77 extreme4 mobo(doesnt have a firewire port) if that helps. I tried using the firewire port to no avail, after looking for a fix I noticed I dont even have a firewire port registered in the device manager on windows 8.1. When I plug something into the firewire port it reads it as an undetectable usb device. Any suggestions on what I should do or should I just by an expansion card?
