I'm looking at the info about that Behringer model, and it sure doesn't look like it would work that way with Premiere. It's not a control surface, it's a mixer with USB output -- so basically you could send mixed digital audio to your computer by manipulating the faders manually, but I don't think it works the same way, say, a Korg Nanokontrol2 would.
I have a similar Behringer mixer (not that model) and WISH it could work as a control surface, but it's basically "all the brains inside the mixer output to your computer as digital audio" rather than "all the brains in the computer with a USB input device controlling them."
I hope that makes sense, and doesn't sound like a buzzkill.
