Nuvoton Virtual Com Port (COM8) Driver

The Nuvoton Virtual Com Port (COM8) driver lets Windows recognize a compatible Nuvoton USB device as a serial communication port, allowing software to exchange data with connected hardware. You may need it when setting up a development board, using a serial-based utility, or troubleshooting a device that appears as unrecognized hardware in Device Manager.

Key Features

• USB-to-serial communication: Provides a virtual COM interface so applications can communicate with compatible Nuvoton hardware through USB.
• COM port identification: Allows Windows to list the device under Ports (COM & LPT) in Device Manager. COM8 is the assigned port number, which may change when you reconnect the device or use another computer.
• Serial software access: Enables compatible terminal programs, configuration tools, and development utilities to open the assigned port using the settings required by your hardware.
• Support for listed Windows versions: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility requirements of the particular driver package and device.

How to Install Nuvoton Virtual Com Port (COM8) Driver

1. Confirm your hardware and Windows version. Check the device model and whether your system uses 32-bit or 64-bit Windows. If necessary, inspect the device’s Hardware IDs in Device Manager to help identify the correct package.
2. Choose a compatible package. Before starting a Nuvoton Virtual Com Port (COM8) driver download for Windows, verify the supported operating systems and hardware. Select the latest version that explicitly supports your setup, and use a trusted vendor or hardware-manufacturer source when looking for a free download.
3. Extract and install the driver. Unzip the package if needed, then run its installer. If no installer is included, open Device Manager, right-click the relevant device, choose Update driver, and browse to the extracted driver folder. Option names vary by Windows version.
4. Reconnect and verify detection. Follow any restart instructions, reconnect the USB device, and check that it appears under Ports (COM & LPT) without a warning icon.
5. Configure your application. Select COM8—or the port number currently shown in Device Manager—and use the serial settings specified by the hardware documentation.

Keep the driver updated when a compatible release addresses connection problems or supports your hardware better. For Windows 10/11 systems, check support separately: Windows 10 is listed here, but Windows 11 compatibility is not confirmed. An update should match your device and operating system, rather than simply being the newest available package.
