I don't know about ordering multiple USB devices, but at least you
should be able to force the internal card to be card 0 by passing
index=0 to snd_intel_hda or whatever driver it needs...
(Probably not helpful to you now but the real solution is to address
cards by name, especially now that ALSA will have a usable device
enumeration API in 1.0.14. So you would configure the streaming
server to stream from "default:UA-25" and monitor "default:HDA-Intel")
