Reply to need help with traktor + external soundcard

I'm using a VCI-100 and recently bought a behringer uca222 so i could cue tracks and monitor. Whenever i select the usb device in traktor, an error message comes up and it closes. Even running it through asio4all, i cant find the headphone output on the drop down list and the sound comes through both the speakers and phones. In desperate need of help!
