I'm using an UA-2 which is quite similar but without the MIDI interface.
The standard ALSA usb driver _does_ support the 'advanced' mode. You have
to restart the module (using modprobe) after each change to mode or sample
frequency.
Contrary to what you seem to say on the Wiki, this device is full duplex
when in standard mode. Nothing special should be required. It is either
capture or playback only in advanced mode.
As far as ALSA is concerced there is one stereo input stream and/or one
stereo output. It doesn't matter to ALSA from/to which connectors the
signal is coming/going to. If you can record from line input then the
mic input should work as well. If you have analog out then the digital
out will work at the same time.
