依照官方文件的確是在usbd_audio_DataIn裡面呼叫DCD_EP_Tx
"usbd_audio_DataIn() and usbd_audio_DataOut() which update the audio
buffers with the received or transmitted data. For Out transfers, when data are
received, they are directly copied into the audiobuffer and the write buffer
(IsocOutWrPtr) is incremented."
但是我現在程式無法進入usbd_audio_DataIn
請問您是如何調用的呢?
