But I think it works these days: http://focusritedevelopmentteam.wordpress.com/2012/04/23/linux-and-focusrit… I have a Focusrite 18i6. It required a quirks-entry in the alsa-kernel-module. That went upstream in linux-3.8. Note that the mixer-interface is proprietary. I reverse engineered it a year ago and wrote the driver for it, but then lost interest - others are carrying on that work now (see above forum). The reason I lost interest is that I think the device is crap. The volume dials don't latch. I set a gain on the Focusrite 18i6 and a minute later it's off by +-1dB. Compared to the other two USB audio-device that I have, the [preamps of the] Focursite 18i6 is the noisiest. Measured with a 200 Ohm termination and jnoisemeter: ~-72dBFS (Flat, RMS) -- the Edirol UA-25 is at -81dBFS and the Presonus 1818VSL at -84dBFS. That make we wonder which award those 'award winning' preamps of Focusrite actually won :) It has gain labels from 0..10 -= other comparably priced devices have latched dials properly labeled and calibrated with dB. I don't know if the same applies to the 18i8 -- Alexandre Prokoudine reported similar findings with a Focusrite 2i4, though. best, robin
