I have this '.asoundrc' file (made before previous postings), but that
does not seem to make a usable card.

I'm expecting that a PCM device should /just/ appear under 'aplay -l', but
that is not happening. Perhaps there is a step I am missing, or I am just
confused about what qualifies a 'working' US-122L.

Do I need to be using a specific version of (userland) Alsa?

It would be nice to get a 'nod' from a person who has the US-122L workin
on their system. But I do appreciate Clemens' help and guidance,
Simon.
