[linux-audio-user] missing snd-usb-audio module in Gentoo

Hi. Amazingly after emerging alsa-lib, alsa-utils, and alsa-oss, running alsaconf, and pushing up the master volume in alsamixer, the sounds worked OOTB. I had to add snd-seq-midi to /etc/modules.autoload.d, as it hadn't autoloaded at bootup. The problem is that even though the midi keyboard shows up in /proc/bus/usb/devices, it does not show up in Qjackctl's midi connect bay. Tried modprobe snd-usb-audio, but it complains that there is no such module. As shown below, the kernel config shows snd-usb-audio there, but commented out. All relevant info further down. Nigel.

But I don't think there's anything here that could cause a problem. # Listing a module here prevents the hotplug scripts from loading it. # Usually that'd be so that some other driver will bind it instead, # no matter which driver happens to get probed first.

Any suggestions apart from "Reinstall the OS" welcome.
