I've been using a FT Pro for 4 years now. I don't recall having to do anything special to get it to work, where "work" == 2 audio in, 2 audio out, at 44.1Khz.

You might want to try just basic stereo, USB1.1 mode, 44.1kHz, and see how that goes. If ALSA can see it, then JACK can be made to see it. What does your /proc/asound/cards , and the /proc/asound/cardX/codecX say?

There were all kinds of modprobe variables (and driver patches) required to get it to work at higher bitrates, but I didn't waste too much time trying to get those going. 44.1K is fine, and stereo is fine too. Works great.

As for the 2 extra RCA jacks on the Pro, there is no way to get them to work as additional JACK ports without some userspace hacks involving resampling and syncing two separate audio interfaces together. They show up as separate ALSA interfaces with a separate word clock.
