5.3.1 Drivers
The ST-LINK/V2-1 requires a dedicated USB driver for Windows
®
available at the
www.st.com
website.
In case the 32F769IDISCOVERY Discovery board is connected to the PC before the driver
is installed, some 32F769IDISCOVERY interfaces may be declared as
unknown
in the PC
device manager. In this case, the user must install the driver files and update the driver of
the connected device from the device manager.
Note:
Prefer using the ‘USB Composite Device’ handle for a full recovery.
