6.2.1 Driver 
Before connecting the Nucleo-64 board to a Windows 7, Windows 8, or Windows 10 PC via 
USB, a driver for ST-LINK/V2-1 must be installed. It can be downloaded from the 
www.st.com website.
In case the STM32 Nucleo-64 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 board to this dedicated driver, 
must be updated in the device manager manually.
Note: It is recommended to proceed using a USB Composite Device, as shown in Figure 7.

6.2.2  ST-LINK/V2-1 firmware upgrade
The ST-LINK/V2-1 embeds a firmware upgrade mechanism for the 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 functionality, bug fixes, support for new microcontroller families), it is 
recommended to visit www.st.com website before starting to use the STM32 Nucleo board 
and periodically, in order to stay up-to-date with the latest firmware version.
