Windows handling of multiple USBs is the culprit with mis-routing audio. I have 3 feeds running off identical USB audio devices to two websites on the same machine and don't have issues, now that I figured that out. Also, Scannercast can be a victim of this just as easily as Oddcast. One thing I did that seemed to help was to use an externally powered hub, rather than the onboard USB ports.
