So you've hit an isochronous cycle timer bug w/this chip (might be
fixed in current upstream, if its the bug I'm thinking of), and then
reading the config rom of node ffc1 failed. That was likely the cable
box.

Ew. That's ugly. Not sure what happened there.

However, from later mails in the thread, seems like you've finally
happened upon a working solution. I hate firewire sometimes. Or at
least the multitude of poorly implemented firewire chips out in the
world.
