Is there another card that ALSA is currently using as the default, or is ALSA not even detecting the USB device?

It is using the on-board souncard by default. The usb device is detected just fine.
Right now I got it working by blacklisting the on-board soundcard. It works for now, but it is definitely not the best way.
