I should use the USB FS on CN5 of STM32F4-Discovery in dual Virtual Com Port (if possible in three VCP).
I made a project started from cubemx with USB_CDC_VCP with USBD_MAX_NUM_INTERFACES = 3 and USBD_MAX_NUM_CONFIGURATION=3 .
It work well but in the pc instal one COM only.

I tryed to modify the usb descriptor manually but it not work fine. I have Always one COM only.
Where i can find un example based on cubemx library whith multiple CDC VCP?
Very Thank.
