Thanks for your e-mail.
First, I downloaed alsa 0.5.12 so I couldn't find usb module.
I downloaded CVS version as you told, and I did compile and install.
but /dev/dsp doesn't atttched.
'lsmod' says snd-usb-audio is unused.
snd-pcm-oss 36836 0 (unused)
snd-mixer-oss 8448 0 [snd-pcm-oss]
snd-usb-audio 24000 0 (unused)
snd-pcm 52544 0 [snd-pcm-oss snd-usb-audio]
snd-timer 9728 0 [snd-pcm]
snd-hwdep 3392 0 (unused)
snd 24008 0 [snd-pcm-oss snd-mixer-oss snd-usb-audio
snd-pcm snd-timer snd-hwdep]
soundcore 3556 3 (autoclean) [snd]
I'll wait your reply, thank you.
