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

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.

It is recommended to proceed using a USB Composite Device, as shown in
