Only thing I can tell you is that the UA-25 works well. It's using the
module snd-usb-audio which Ubuntu loads by itself.
It works in basic and advanced mode the way it is supposed to work,
which means plugging out and back in whenever you change those modes or
the sample rate at the device.

You could try to run it in basic mode using 44.1kHz. Maybe at least
that works.

I'm kinda surprised that it doesn't work, as the device doesn't look
that different to me.
