[Alsa-user] ALSA not detecting M-Audio USB Duo?

[Colin F. <col...@gm...>]

The subject says it all, really. Apparently this card is supported, I
have the usb card drivers compiled in, but nothing. When I connect the
card, I get the following in /var/log/messages:

But when I run alsaconf, it just doesn't see the card. I can't seem to
get ALSA to see it.

Is there anything obvious I'm doing wrong? I'm running Gentoo Linux,
2.6.11. One thing worth noting is that I'm using the card drivers from
Portage rather than the Kernel, but it looks like it's all being
detected correctly.

Thanks in advance for any help.
