Never download "driver updater" tools from third-party sites. The safest source is your motherboard's official support page:
To maintain peak performance and avoid future headaches:
Cause: A corrupted Nuvoton driver causing continuous interrupt requests.
Solution: Completely remove the driver using pnputil in elevated Command Prompt:
pnputil /enum-drivers
pnputil /delete-driver oemXX.inf /uninstall
Then reinstall the best driver from your motherboard vendor.
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
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.
Windows Update: Check Optional Updates in Windows 10 settings first, as Microsoft often hosts certified versions of these drivers. Common Troubleshooting

For Windows 10, the most reliable version of the Nuvoton Communications Port driver is v1.2.2020.1225, released in December 2020. This driver is designed for hardware IDs PNP0500 and PNP0501 and is compatible with both Windows 10 and 11. Recommended Driver Versions
Depending on your specific hardware age, you may find these versions useful:
Version 1.2.2020.1225 (Latest): Best for modern Windows 10/11 systems using nuvserial.inf.
Version 1.1.2017.1121: A stable alternative if the latest version causes issues on older hardware.
Version 1.0.2011.1109: Often found on legacy Intel motherboards like the DH61CR. Where to Download
Since Nuvoton primarily provides hardware to other manufacturers (OEMs), the best place to get a stable driver is from your computer manufacturer's support site (e.g., Dell, HP, or Intel). If you are a developer, you can find virtual COM port tools and open-source drivers on the Nuvoton Official Technical Blog. Installation Tips
Check Device Manager: Open Device Manager and look under "Ports (COM & LPT)" to see your current driver version.
Use Windows Update: Windows 10 often carries these drivers in its optional updates database.
Clear Conflicts: If the port isn't working, ensure no other drivers are assigned to that specific COM port before installing.
The Nuvoton Communications Port driver is a critical software component that enables Windows 10 to interface with Nuvoton's hardware, typically used for serial communication in embedded systems, modems, and motherboards. While these drivers are often stable for decades, ensuring you have the "best" version for Windows 10 involves sourcing from authoritative repositories to maintain system stability and peripheral performance. Understanding the Nuvoton Communications Port
The driver identifies hardware under IDs such as *PNP0500 or *PNP0501. It is commonly found on older Intel-based motherboards (like the Intel DH61CR) to manage legacy serial (COM1) ports. Modern applications also use it for USB-to-Serial bridge functions, such as Nuvoton's Nu-Link2-Pro, which monitors I2C, SPI, and CAN data through a virtual COM port. How to Find and Install the Best Driver
For Windows 10, the most reliable way to obtain the latest official driver is through established distribution channels rather than third-party "driver updater" tools. Nuvoton Communications Port (COM1) Driver for INTEL_

Nuvoton Communications Port driver for Windows 10 is essential software that enables your operating system to interface with Nuvoton hardware, such as embedded controllers, modems, and serial communication interfaces. While Windows 10 often identifies these ports automatically, a dedicated driver is frequently required for specialized hardware like the Nu-Link2-Pro adapter or legacy motherboard components. Best Methods to Obtain the Driver
The safest and most reliable way to get the correct driver is through official manufacturer channels. Motherboard/PC Manufacturer Support
: Visit the support page of your specific hardware brand (e.g., ) and search for your model to download the latest Serial Port Nuvoton Official Website
: For specialized development tools like the Nu-Link2-Pro, download the NuTool-USB to Serial Port
software, which includes the necessary CDC (Communication Device Class) drivers. Windows Update
: Often, Microsoft provides generic drivers that work perfectly for standard COM port functionality. How to Install and Update on Windows 10
If the driver is not installed automatically, you can manually add it: Open Device Manager and select Device Manager Locate the Port : Expand the Ports (COM & LPT) Update Driver : Right-click on "Communications Port" and select Update driver Manual Selection : If you have the file, choose "Browse my computer for drivers"
and navigate to the folder where you extracted the driver files. Add Legacy Hardware : If no port is visible, go to Action > Add legacy hardware
in Device Manager and manually select "Ports (COM & LPT)" to trigger the installation wizard.
