Thanks, we tried it today with PureDyne 9.10 "Carrot and Coriander".
modprobe and chmod reported no errors, but JACK didn't recognize the
AudioFire12.

When you say "backend" in QJackCtl, are you talking about the driver, or
something else? I just noticed now (at home on my laptop without any
firewire device) that there's a "firewire" option on the Driver drop down.

We use a Firewire 800 PCIExpress card, I forget the brand. I didn't have
the time to check to see if the card is being recognized.
