/*
* RME Babyface Pro (FS)
*
* These devices exposes a couple of DSP functions via request to EP0.
* Switches are available via control registers, while routing is controlled
* by controlling the volume on each possible crossing point.
* Volume control is linear, from -inf (dec. 0) to +6dB (dec. 46341) with
* 0dB being at dec. 32768.
