I just bought a Presonus FireBox, but I'm having some problems with it. I'm on a 2007 MacBook Pro, osx 10.5.8 I plug the unit into the wall, it powers up just fine, red light. I then plug the firewire cable from the Firebox into the FW 400 input on my mac. The light on the firebox goes blue, as though the connection has been established, but the computer doesn't recognize it. I've tried the PRAM/NVRAM reset and SMC reset to no avail. Under system profiler>hardware, while the FireBox is plugged in, it says, If the FireBox is plugged in upon startup, it just says... And lastly, if nothing's plugged in to the FW port, it says... Any ideas?
