- /** Sends a given data buffer from PROGMEM space to the attached USB host, if connected. If a host is not connected when the
- * function is called, the string is discarded. Bytes will be queued for transmission to the host until either the endpoint
- * bank becomes full, or the \ref CDC_Device_Flush() function is called to flush the pending data to the host. This allows
- * for multiple bytes to be packed into a single endpoint packet, increasing data throughput.
- *
- * \pre This function must only be called when the Device state machine is in the \ref DEVICE_STATE_Configured state or
- * the call will fail.
- *
- * \note This function does not exist on architectures that do not have a separate flash memory space.
- *
- * \param[in,out] CDCInterfaceInfo Pointer to a structure containing a CDC Class configuration and state.
- * \param[in] Buffer Pointer to a buffer containing the data to send to the device.
- * \param[in] Length Length of the data to send to the host.
- *
- * \return A value from the \ref Endpoint_Stream_RW_ErrorCodes_t enum.
