+ * Focusrite's implementation of it. Eventually quirks may be sufficient but

+/* Mixer Interface for the Focusrite Scarlett 18i6 audio interface.
+ *
+ * The protocol was reverse engineered by looking at communication between
+ * Scarlett MixControl (v 1.2.128.0) and the Focusrite(R) Scarlett 18i6
+ * (firmware v305) using wireshark and usbmon in January 2013.
+ * Extended in July 2013.
+ *
+ * this mixer gives complete access to all features of the device:
+ * - change Impedance of inputs (Line-in, Mic / Instrument, Hi-Z)
+ * - select clock source
+ * - dynamic input to mixer-matrix assignment
+ * - 18 x 6 mixer-matrix gain stages
+ * - bus routing & volume control
+ * - automatic re-initialization on connect if device was power-cycled
