i solved like the following: - add snd-usb-* (and oss audio module) to hotplug's blacklist to avoid to load them from the modules.usermap. - add a usermap for the usb audio devices to call its own start-up script. the script starts the alsasound init script inside before loading the snd-usb-audio module (if no /proc/asound exists), so that it asssures that the normal PCI devices are assigned prior to usb devices.
