Just powering on, these devices below wait to download firmware. - Firewire Audiophile - Firewire 410 - Firewire 1814 - ProjectMix I/O
But firmware version 5058 or later, flash memory in the device stores the firmware. So this driver can enable these devices by sending a certain cue to load the firmware. To reading these codes, this cue is a kind of Bootloader Commands. The role of this cue is to initialize configuration to factory settings.
I think this functionality should be implemented in user-land. FFADO already have 'ffado-bridgeco-downloader' to take the device to download firmware. To read these codes, this cue is a kind of Bootloader Commands. The role of this cue is to initialize configuration to factory settings
