Not being a huge Apple enthusiast, my experience with Firewire and all its ins and outs is quite minimal.
However, at my new job, they use it extensively. We seem to be having problems where after using a cable for a short time (a matter of months) all input methods fail when said cable is plugged in. Removing the cable solves the problem. A new cable works, but again, only for a short period of time.
Do the cables go badly that quickly? Or is there something a little more obscure that I'm missing. All of the sites I can find about Firewire only tout its wonders and provide no trouble shooting techniques.
Anything you can think to try would be appreciated, I'm running out of ideas.
