There is usually more stuff when you plug in a usb card. Strange. I
can't remember but things like registering it with snd-usb-audio and so
on.

Strange again. I would guess that for some reason the firmware was not
loaded. Alsa does recognize the device but there are no audio streams
available. What happens if you try to load the firmware manually? I
imagine that it would be something like:
  /usr/bin/usx2yloader

Come to think of it, that must be the problem. I see above that hotplug
runs /usr/bin/us428control, instead of usx2yloader. I don't know why
that would be.
