There was a patch to the ALSA mixer code a while ago introducing some device-specific "quirks", and it works out of the box on 3.something and newer kernels. The ADAT port is input only. I haven't used it yet. It has in&out MIDI DIN ports which I have tried and they work normally with ALSA. I have managed to run it with JACK at 64 samples, 2 buffers @ 44100 Hz, with an RT patched 4.x kernel. That's a bit flaky though, 128 samples is more reliable. There is a "second gen" version available now which promises even lower latency, but I don't know whether that is a change in hardware or just a Windows/Mac driver thing. The naming scheme is a bit... misleading. Actually it has 8 analog inputs (4 with mic preamp, 4 line-in, all balanced) and 6 analog outputs (balanced "Monitor" line-level left&right, and 2 stereo headphone outs). There's one stereo SPDIF out. You can get 8 more inputs with ADAT. Overall, I'm pretty happy with it.
