Re: Usage of USB driver in isochronous mode (STM32)
This is an old thread but I just banged my head against a bug for several days and here's the answer....
When doing asynchronous USB audio (where you have a feedback endpoint that sends a 3-byte feedback value to the host, typically every 32ms (e.g. 1<<5 in the 'refresh' field of the endpoint ...
