Firewire Connectivity

I have a Phonic Firewire 18 MKII mixer using VISTA. Audacity does not recognize any of my firewire inputs. I also have Cubase LE and it does recognize my Firewire connection. I can not find the setting that will allow me to change from mike to line to ASIO Firewire inputs.

Please help. I love this software and want to use it with my new Firewire connection.

Don’t double post, please.
