Hi All,
I am now working at build a USB sound card with MIC in STM32F4 Discovery board. Now I already had separate working speaker and microphone usb program. When I combine those two, the USB cannot start, it fails at set_configuration part. What's wrong here? Descriptor or callback function?
Thanks
