External Sound Card Question

Hello.. So I have an external USB Soundcard-
Sabrent- Windows Vista- PC
I can select it as my main output for Cross DJ 2.6.0, and it works, but I cannot select it as my Output #2 (does not come up in my dropdown list).
So it seems that Cross DJ recognizes the SC but it is not an option for my Output 2 so i can use it as my CUE..
Suggestions? Help?
