I am trying to transmit and receive data on a STM32F7 (USB HOST CDC). After I receive and transmit bytes a few times my IN pipe shows a URB_Status of USBH_URB_NOTREADY and never reaches a USBH_URB_DONE state.

If there are 2x internal DACs in the STM32F407XX MCUs, why does the STM32F407VG Discovery Board need an external DAC for audio applications?

I'm very new to the STM32, so sorry if this sounds stupid. As far as I could understand looking at the datasheets, the STM32F407XX has 2 DACs, but when embedded in the discovery board an external DAC (CS43L22) is used. Why is that?
