Hi, I'm using STM32f407 for a USB project. I use CDC class (STM32_USB_Device_Library) for implementing USB device on my OLIMEX EVAL board.
When I connect my board to PC, it appear as VCP, as shown in the figure attached (1).
It's correct?

My usbd_desc.c and usbd_cdc.c  are attached. Are correct?

I don't have implemented usbd_cdc_interface.c, it's a problem for the configuration of device?

Thanks for your help.
