ALSA: bebob: Send a cue to load firmware for M-Audio Firewire series
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. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
