Windows 10 Best [new] | Nuvoton Communications Port Driver

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 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.

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 , which monitors I2C, SPI, and CAN data through a virtual COM port.
