I just upgraded from the Behringer FA1616 to the MOTU 828mk3 so I could get word clock support. I've connected the interface to my Pacarana, it's in Firewire mode, I've got clock sync and ADAT channels up... but the interface doesn't show up in the interface list in DSP Status. I know it's seeing it on the FW bus, because if I power it off the Pacarana displays a notice that the device was lost. I've tried Control -> Rescan a bunch of times, but still nothing shows up. I'm stumped as to what to try next.
