12 | * Just powering on, Firewire 410/Audiophile/1814 and ProjectMix I/O wait to |
13 | * download firmware blob. To enable these devices, drivers should upload |
14 | * firmware blob and send a command to initialize configuration to factory |
15 | * settings when completing uploading. Then these devices generate bus reset |
16 | * and are recognized as new devices with the firmware. |
17 | * |
18 | * But with firmware version 5058 or later, the firmware is stored to flash |
19 | * memory in the device and drivers can tell bootloader to load the firmware |
20 | * by sending a cue. This cue must be sent one time. |
21 | * |
22 | * For streaming, both of output and input streams are needed for Firewire 410 |
23 | * and Ozonic. The single stream is OK for the other devices even if the clock |
24 | * source is not SYT-Match (I note no devices use SYT-Match). |
25 | * |
26 | * Without streaming, the devices except for Firewire Audiophile can mix any |
27 | * input and output. For this reason, Audiophile cannot be used as standalone |
28 | * mixer. |
29 | * |
30 | * Firewire 1814 and ProjectMix I/O uses special firmware. It will be freezed |
31 | * when receiving any commands which the firmware can't understand. These |
32 | * devices utilize completely different system to control. It is some |
33 | * write-transaction directly into a certain address. All of addresses for mixer |
34 | * functionality is between 0xffc700700000 to 0xffc70070009c. |
