I would like to point you to two commands. First:

$ man jackd

.. shows:

OPTIONS
       -d, --driver backend [backend-parameters ]
              Select the audio interface backend.  The current  list  of
sup‐
              ported backends is: alsa, coreaudio, dummy, freebob, oss sun
and
              portaudio.  They are not all available on  all  platforms.
All
              backend-parameters are optional.

There doesn't seem to exist a supported backend called "firewire".

Second:

$ aplay -l

.. will list your "PLAYBACK Hardware Devices" recognized by alsa.

If your card is listed there you could run jack with alsa backend and
select your preferred device (e.g. hw:0, hw:1, etc..). Perhaps using
qjackctl would make both easier. Otherwise you could try:

$ jackd -d alsa -d hw:0

Regards,
Funs​
