The system-supplied function driver for serial ports registers an instance of this device interface class for a serial port. The following samples (on Github) register an instance of this class for a serial port: The Serial sample; The Virtual serial driver sample (UMDF 1.0) The Virtual serial2 driver sample (KMDF). To install the virtual COM port drivers, on the Device Manager screen, select Update Driver Software option. In the driver software installation window by default, the Don’t Install option is highlighted in the window. STSW-STM32102 - STM32 Virtual COM Port Driver, STSW-STM32102, STMicroelectronics.

Install Drivers for STMicroelectronicsDiscovery Boards

Before you start working on Support Package for STMicroelectronics^® Discovery™ boards, you must first configure your computer to detect the STMicroelectronics Discovery board.

Drivers Stmicroelectronics Port Devices Replicator

To detect the Support Package for STMicroelectronics Discovery board:

Drivers Stmicroelectronics Port Devices Gigabit

1. Connect the STMicroelectronics Discovery boardto a USB port of your computer.

   When you connect, the STMicroelectronics Discovery board detection light starts blinking and then stops when your computer detects the Discovery board.

   The STM32F4–Discovery board is as shown.

   The STM32F746G-Discovery board is as shown.

   The STM32F769I-Discovery board is as shown.

2. On the STSW-LINK009 page, in the Get Software section, click . Download the zip file on your computer, and extract the driver installation executable from the zip file. This step requires you to have the login credentials of the STSW-LINK009 web page.

   To install the driver software, you can use either of the following methods:

   • Double-click the extracted executable dpinst_amd64.exe, and follow the installation steps.

   • Right-click Device Manager > Other Devices > ST-Link Debug and then click Update Driver Software. Select the option Browse my computer for driver software. In the Browse window, specify the path of the folder that you have unzipped, for example, C:en.stsw-link009.

3. After the driver is detected, you see the STMicroelectronicsSTLink dongle under the Universal Serial Bus devices asshown.
