Hello,

is it a custom board ? or an ST board ?

Maybe you simply need to install the ST-Link drivers:

it's an ST board.

i wanna know if the usb st-link and the usb user on the STM32F3 must be the two of them related to the pc or not

To start with your board, you'll see the debug port and virtual COM port on the USB ST-LINK port.

Please check on ST website whether there is a user manual for the board you have.
