After reading this guide, you should understand that there is no one-size-fits-all "best" driver. The optimal driver is the one provided by your motherboard manufacturer, WHQL-signed for Windows 10, and matched to your specific Nuvoton chip model.
Start by visiting your motherboard’s support page. If that fails, fall back to Nuvoton’s official reference drivers. Avoid third-party driver updaters at all costs. With the correct driver installed, your Nuvoton Communications Port will function reliably, whether you’re programming a microcontroller, controlling legacy industrial equipment, or simply using hardware monitoring tools.

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.
After surveying countless forum threads (from EEWeb to the official Nuvoton forum) and testing across multiple Windows 10 builds (Pro, Enterprise, and LTSC), a consensus emerges. The most stable driver for the majority of Nuvoton USB-to-UART bridge chips is version 2.14.0.0 or the equivalent NuMicro VCOM driver package released in late 2019. This version is praised for its reliable enumeration—meaning the COM port appears consistently after reboot or sleep, a common failure point for older 1.x drivers. It supports baud rates up to 3 Mbps and properly implements the DTR (Data Terminal Ready) and RTS (Request to Send) flow control lines, which are essential for programming microcontrollers.
Conversely, newer experimental drivers designed for Windows 11 have been reported to cause the “Device Descriptor Request Failed” error on some Windows 10 legacy builds. The best practice is to avoid beta or Windows 11-centric drivers.
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.
