if it's any comfort, having a Firewire interface isn't any better... for some reason my computer just decided one day not to recognize my Behringer FCA202 anymore. I've tried plugging and unplugging it a million times, restarting the computer, reinstalling the drivers, EVERYTHING and it just doesn't work (although the light on the interface says it's connected). I guess the best way to go is just to have an internal card...
