I'm also a newbie with firewire, but had more success with FFADO, (it is more
current anyway).. I don't have an edirol, but a focusrite saffire pro 10.

Simply install it, fire up ffado-dbus-server run qjackctl and  select firewire as
the driver. I am able to get better latency performance with ffado, way better
than freebob but even better than ALSA (under 3ms with 44100 and 48000 khz)...
