Hello!
I have a problem. I created a USB audio device project in CubeMX. Then I changed the descriptors and related functions to get a device like a microphone. The device is detected correctly in the Windows system. But there is a problem: DataIn endpoint callbacs and SOF events are not raised. I cannot process and send data. I am interested in implementation using the latest version of the HAL + USB device library (I only find examples use old versions and USB OTG + CMSIS). Why might Isochronus DataIn callbacks be missing?
