/*
* 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.
