+ * Just powering on, Firewire 410/Audiophile/1814 and ProjectMix I/O wait to
+ * download firmware blob. To enable these devices, drivers should upload
+ * firmware blob and send a command to initialize configuration to factory
+ * settings when completing uploading. Then these devices generate bus reset
+ * and are recognized as new devices with the firmware.
+ *
+ * But with firmware version 5058 or later, the firmware is stored to flash
+ * memory in the device and drivers can tell bootloader to load the firmware
+ * by sending a cue. This cue must be sent one time.
+ *
+ * For streaming, both of output and input streams are needed for Firewire 410
+ * and Ozonic. The single stream is OK for the other devices even if the clock
+ * source is not SYT-Match (I note no devices use SYT-Match).
+ *
+ * Without streaming, the devices except for Firewire Audiophile can mix any
+ * input and output. For this reason, Audiophile cannot be used as standalone
+ * mixer.
+ *
+ * Firewire 1814 and ProjectMix I/O uses special firmware. It will be freezed
+ * when receiving any commands which the firmware can't understand. These
+ * devices utilize completely different system to control. It is some
+ * write-transaction directly into a certain address. All of addresses for mixer
+ * functionality is between 0xffc700700000 to 0xffc70070009c.
