STM32F4 Discovery board Audio Card

I would like to use the discovery board as a USB audio card which can use usb play music from PC and record sound to PC. When I initialize the USB, I think I need to configure both EP_out and EP_in. SO in usbd_audio_Init() function, I need to use DCD_EP_OPEN function twice? One is for out and the other is for in.
