Note that DCX-3200 is just a text label, and has nothing to do with
its supported status.  What allows or prevents a firewire box from
working is the code containing the vendor and model IDs for the
particular version of the box you've got.  The DCX-3200 can (and does)
have numerous vendor and model IDs, and each time a new one is
discovered, it needs to be added to the code.  Not ideal, but it's
just the way it works, sadly.  Anyway, the models and vendor IDs of
the DCX-3200 we knew of up until .24 are supported.  If it doesn't
work for you, it is probable that you have a vendor or model ID we
have not yet seen.
