If you want to use the alsa-driver packages with gentoo, you must not have alsacompiled with the driver.

Thesnd_usb_audio will be loaded by hotplug before at alsasound load the alsamodules, and the regular sound card will be the second sound card. If it is the case, you have to add"snd-usb-audio" (without the double quotes) in /etc/udev/blacklist and alsasoundwill work as expected.
