Hi how can i use UART Pins via USB FS. I am currently using the USB TO UART connector on my devboard but how can i use the USB FS connection to make uart pins working?

I want to use uart3 PC10 and PC11 Pins but its not working with the baudrate if i connect usb fs but its working with usb to uart why?

Below pictures of the mcu and the dev board i marked the connections:

Thanks for everyone who helps!
