Hi,

I'm working in an audio project. We use stm32f407 like a USB audio device to get audio data from PC then send out by I2S module. We are using stm32f4 Discovery kit and STM32cubeMX. After generate code, i change nothing and flash to Kit; my PC identifies that STM Audio device but there isn't any data send to my kit when play music. My question is:

+ i don't know which function is callback when data stream from PC to Kit.

+ is there any document of STM about this topic ( usb device ).

this is my config in STM32cubeMX
