ST-LINK/V2-1 are:
•
USB software re-enumeration
•
Virtual COM port interface on USB
•
Mass storage interface on USB
•

4.1.1 Drivers
Before connecting the 32F469IDISCOVERY 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
webpage.
If the 32F469IDISCOVERY board is connected to the PC before installing the driver, the
Windows
®
device manager may report some USB devices found on 32F469IDISCOVERY
as “Unknown”. To recover from this situation, after installing the dedicated driver
downloaded from the
www.st.com
webpage, the association of “Unknown” USB devices
found on 32F469IDISCOVERY to this dedicated driver, must be updated in the device
manager manually. It is recommended to proceed using the
USB Composite Device
line, as
