I have a Babyface Pro, and I'm quite satisfied with it.

With Linux it works in class-compliant mode. You have all the
12 inputs and outputs (4 analog + 1 ADAT), but no hdspmixer.

Most things (sample rate, input and output gains, phantom 
power), can be controlled from the unit itself. This includes
mixing, but limited to the 4 analog I/O and the first two
ADAT channels. Also no panning, only L,C,R.

Audio quality is perfect. Just one thing to be aware of:
the first two analog outputs are REALLY balanced, i.e. you
get two antiphase signals on pins 2 and 3 of the XLR. 
Which means that to connect to an unbalanced input you
need a  non-standard cable, leaving pin 3 unconnected.

And strangely enough, analog inputs 3 and 4 (on TRS) are
*not* balanced. 



A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
