I have later tried it with usb to audio dongle that comes with Logitech headset and it was detected and new card appeared in /proc/asound/cards but that was all. One also needs to tell the system to actually use that card instead of the builtin one which means it needs messing with ALSA configuration files and/or installing additional ALSA userspace utilities. So if you can't figure out the insmod stuff, don't bother, it needs additional tweaking.
