If anyone has any objections, please let me know. ------------------ From: David Heimann commit 6a3439a417b910e662c666993798e0691bc81147 upstream. The RODE AI-1 audio interface requires implicit feedback sync between playback endpoint 0x03 and feedback endpoint 0x84 on interface 3, but doesn't advertise this in its USB descriptors. Without this quirk, the device receives audio data but produces no output.
