I am using a STM407VET6 development board, and when I connect it via USB, it is recognized as "STM32 ST-Link" as a USB device, but not as a VCP. How can I solve this problem?

Perhaps connect to the other USB port?

If this is the STM32F407-DISCO board, the TOP/NORTH connector goes to an STM32F1

The BOTTOM/SOUTH Micro-AB connects to the STM32F4, and whatever software you have running on that.

Try re-installing all drivers.

TOP/NORTH connector to a desktop PC.

The driver has already been reinstalled.

When other boards (F407G-DISC, NUCLEO-F446RE) are connected, they are recognized as VCP.

This board has a ST-LINK/V2-A which does not include VCP. See

STM32F4DISCOVERY Data brief and

TN1235 Overview of the ST-LINK versions.

Can add VCP by soldering 2 wires, see UM1472 Discovery kit with STM32F407VG MCU
