Hi, everyone!

Using VCOM example with one port, some time ago i made a project with two ports.

And now, i have a one little question - how many virtual serial ports can i make with STM32 (USB CDC class device), where i have 8 bidirection endpoints (and ENDP0 is using for system puporse)? I think only 3(1 endpoint - managment interrupt(IN), 2 endpoints data IN and OUT for each virtual port), is it that?

I'm attempting to do exactly what you've done. Any chance you could share specifically what you changed in the example to do this?
