/* The protocol was reverse engineered by looking at the communication

* (firmware 1083) using usbmon in July-August 2018.
* Scarlett 6i6 support added in June 2019 (thanks to Martin Wittmann

+ * Scarlett 4i4/8i6 Gen 3 support added in May 2020 (thanks to Laurent
+ * Debricon for donating a 4i4 and to Fredrik Unger for providing 8i6
+ * usbmon output and testing).
+ *
+ * Scarlett 18i8/18i20 Gen 3 support added in June 2020 (thanks to
+ * Darren Jaeckel, Alex Sedlack, and Clovis Lunel for providing usbmon
+ * output, protocol traces and testing).
+ *
+ * Support for loading mixer volume and mux configuration from the
+ * interface during driver initialisation added in May 2021 (thanks to
+ * Vladimir Sadovnikov for figuring out how).
+ *
+ * This ALSA mixer gives access to (model-dependent):
* - input, output, mixer-matrix muxes
- * - 18x10 mixer-matrix gain stages
- * - gain/volume controls
+ * - mixer-matrix gain stages
+ * - gain/volume/mute controls
* - level meters

+ * - holding down the 48V button for five seconds while powering on
