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.

Hi lor3n7o,

USB composite isn't supported yet by CubeMX.

I report your request internally for farther review. We will keep you informed if we have more details on this regard.

There is un example not based on cubemx library with multiple CDC VCP on USBFS on stm32f4,on which I can relate for implementation in may project?

In the meantime I might try to do a manual edit.
