The Nuvoton Communications Port driver (often identified as nuvserial.sys or nuvserenum.sys) is a component primarily used for serial communication in industrial hardware, specific motherboards, and development tools like the Nu-Link2-Pro. Key Takeaways & Driver Performance
Stability & Issues: While generally stable for legacy serial needs, this specific driver has been linked to Blue Screen of Death (BSOD) errors on some Windows 10 versions, often caused by the nuvserial.sys file.
Modern Compatibility: Windows 10 typically provides a generic Microsoft driver (dated 2006) for standard COM ports that works for most basic tasks. If you are using specific Nuvoton development hardware, the manufacturer's dedicated driver is required for features like Virtual COM Port support.
Latest Version: The most recent stable release widely cited for Windows 10 is Version 1.2.2020.1225, dated December 25, 2020. Where to Get the "Best" Version nuvoton communications port driver windows 10 best
To avoid malware often found on third-party "driver update" sites, you should prioritize these sources:
Direct Manufacturer: Download via Nuvoton's Technical Support or their GitHub repository (OpenNuvoton) for open-source tools.
Motherboard Support: If the port is built into your PC (e.g., an Intel DH61CR or Biostar board), download it directly from the PC manufacturer's support page rather than a generic search. The Nuvoton Communications Port driver (often identified as
Windows Update: Check Optional Updates in Windows 10 settings first, as Microsoft often hosts certified versions of these drivers. Common Troubleshooting

Here’s a deep, structured look at the Nuvoton Communications Port driver on Windows 10 — what it is, common issues, and best practices for handling it. Part 3: Where to Find the Best Nuvoton
WARNING: Avoid third-party driver updaters (Driver Booster, Driver Easy, etc.) for this specific component. Many of these tools install generic serial drivers or, worse, malware disguised as Nuvoton drivers.
Before diving into drivers, let’s understand the hardware. Nuvoton Technology (formerly a division of Winbond) manufactures Super I/O controllers. These chips manage low-speed legacy ports on your motherboard, including:
The "Communications Port" in Device Manager (typically labeled COM1 or COM2) allows software applications—such as industrial control systems, diagnostic tools, or legacy hardware programmers—to communicate via serial protocols.
When Windows 10 fails to automatically detect the correct driver for the Nuvoton chip, the device appears under "Other devices" as missing or malfunctioning.
A: Open Command Prompt as Admin → mode. If you see "Status for device COMx" without errors, the port is active. Alternatively, use Get-WmiObject Win32_SerialPort in PowerShell.
