As I have found out, it is not necessary to have the same EP number for IN and OUT for rate feedback to work with a Linux or OSX host. This may be a requirement for Vista/Win7 hosts though. We are still doing testing.
Hi Alex,
thanks a lot! You made my day (c: Using EP5 for feedback makes it working. So I now get the data out even in async mode. Currently I have a problem left that channel assignment jumps here and then. Probably a buffering issue... Also neither a SRC4192 (sample rate converter) nor a PCM1794 (dac) seem to be able to understand what I am sending right now... Not sure why. Looking at the measurements it really looks like a proper I2S signal.
Seems you implement something quite similiar as I do. How did you design the measurement for actual feedback data to provide? Following the suggestion in the spec?
