update:

after load modul snd-usb-audio, per sudo modprobe snd-usb-audio.
modprobe does not hang anymore, BUT now khubd gets 100% cpu and cause hang the whole system after about 1minute.
the process khubd will not appear in systemmonitor, and i cant kill him!

tested it on 2 Ubuntu 10.04 2.6.32-27-generic systems with alsa 1.0.23.
