Nuvoton Communications Port Driver for Windows 10 — Best Options and Setup Guide

The Essential Guide to the Nuvoton Communications Port Driver on Windows 10

If you own a modern motherboard—particularly one designed for industrial, embedded, or high-end consumer use (e.g., ASRock Rack, Supermicro, or certain Gigabyte models)—you may have noticed a device in Device Manager labeled "Nuvoton Communications Port." While it sounds obscure, this driver plays a critical role in system monitoring and hardware communication.

This guide explains what the Nuvoton COM port does, why you need it, and the best practices for installing and maintaining it on Windows 10.

Troubleshooting Common Issues with the Nuvoton COM Driver on Windows 10

Even with the best driver, you may encounter problems. Here is how to solve the most frequent ones.

2. Typical Windows 10 Behavior

Built-in driver support: Windows 10 includes a generic serenum.sys and serial.sys driver for standard 16550-compatible UARTs, which covers most Nuvoton COM ports.
Driver version: Usually dated from Microsoft (e.g., 2006) — this is normal and stable for basic serial functions.
Resources: Uses legacy IRQ (often IRQ 3 or 4) and I/O address range like 0x2F8 or 0x3F8.

Step 1: Identify the Hardware ID

Press Win + X → Device Manager.
Look for "Other Devices" → "Nuvoton Communications Port" or "Unknown Device."
Right-click → Properties → Details tab → Hardware Ids.
Write down the VEN_ and DEV_ codes (e.g., VEN_1E69&DEV_7A59).

This confirms you’re targeting the right chip.

Final Recommendation

Always prefer drivers from your motherboard manufacturer's support page over generic downloads.
Keep the driver only if you use hardware monitoring or serial devices. If not, you can disable the device in Device Manager without harming the system.
Avoid third-party driver updaters—they often misidentify the chip and install incompatible versions.
If the driver is missing and you don't need COM port functions, consider disabling the device to clear the error flag.

When in doubt, check your motherboard’s BIOS for "Super I/O Configuration" to see if the COM port is enabled or can be disabled—sometimes the simplest solution is just turning off what you don't use.
