Usb Duo & Logic 4.7.3 Options

[mr c]

Hey Guys-
I was wondering if anybody out there was using the duo with Logic 4.7.3? I just got the interface and I'm having some problems with the setup. I got the drivers installed and went to the Apple/Control Panel/Sound and selected the duo as my audio in and out. But when I boot up Logic, and look back at the sound panel, it no longer shows the usb device. And if I pick a track to record in Logic, I can see a signal coming in, just no playback. I have selected the USB Asio in my audio setup in Logic, but just can't get it to work. Anybody got any thoughts?

Peace,
C
