In case the STM32 Nucleo-64-P board is connected to the PC before installing the driver,
the PC device manager may report some Nucleo interfaces as 'Unknown'. To recover from
this situation, after installing the dedicated driver, the association of 'Unknown' USB devices
found on the STM32 Nucleo-64-P board to this dedicated driver, must be updated in the
device manager manually.
Note: It is recommended to proceed by using USB Composite Device, as shown in

ST-LINK/V2-1 firmware upgrade

The ST-LINK/V2-1 embeds a firmware upgrade mechanism for in-situ upgrade through the
USB port. As the firmware may evolve during the lifetime of the ST-LINK/V2-1 product (for
example new functionalities, bug fixes, support for new microcontroller families), it is
recommended to keep the ST-LINK/V2-1 firmware up to date before starting to use an
STM32 NUCLEO-G070RB or NUCLEO-G071RB board. The latest version of this firmware
is available at the
