ALSA: usb-audio: Add delay quirk for all Logitech USB devices (54a2a389) · Commits · 戴 / test

Found one more Logitech device, BCC950 ConferenceCam, which needs the same delay here. This makes 3 out of 3 devices I have tried. Therefore, add a delay for all Logitech devices as it does not hurt. Signed-off-by:
