Asmedia Asm1083 Serial Port Driver Windows 10 ★

Before downloading any driver, you must correctly identify the hardware IDs.

No. Windows 10 does not include a native, dedicated driver for the ASMedia ASM1083 as a serial port controller. The ASM1083 is a bridge chip; Windows 10 has generic PCI-to-PCI bridge drivers that handle the basic bridging function, but they do not automatically enable the serial port functionality that might be attached behind that bridge.

If you install a PCIe serial port card based on the ASM1083, you will likely see:

The ASM1083 includes an internal serial port (UART) for debugging and bridge management. Under Windows, this component is often enumerated as a separate "Serial Port" device. Even if you are not using the serial port physically, Windows 10 still tries to load a driver for it. When the correct driver is missing or incompatible, you see an error. asmedia asm1083 serial port driver windows 10

The ASMedia ASM1083 can be made to work on Windows 10, but it requires patience and the right driver. The key is to identify the actual serial controller chip behind the ASM1083 bridge. Once you locate a Windows 10 driver for that UART (often MosChip or Oxford), the serial ports will function correctly.

For most users, however, switching to a modern PCIe serial card with native Windows 10 support or a high-quality USB-to-serial adapter is the more reliable, long-term solution. The ASM1083 belongs to a transitional era of PC hardware, and while it is not obsolete, its driver support on Windows 10 is strictly legacy—maintained by third-party card vendors, not by Microsoft or ASMedia.

The ASMedia ASM1083 is primarily a PCIe to PCI bridge chip. It does not natively provide serial port functionality; instead, it bridges modern PCIe-only motherboards to legacy PCI slots. If you see a "PCI Serial Port" error in Windows 10 Device Manager associated with this chip, it usually means a legacy expansion card (like an RS-232 serial card) is plugged into a PCI slot provided by the ASM1083, and that specific card requires its own driver.  Driver & Installation Overview 

Bridge Function: The ASM1083 chip itself is generally plug-and-play on Windows 10. Windows typically uses the built-in "PCI-to-PCI Bridge" driver to manage it. Before downloading any driver, you must correctly identify

The "PCI Serial Port" Error: If a device appears as an "Unknown Device" or "PCI Serial Port" with a yellow exclamation mark, you are likely looking for the driver of the connected card (e.g., a Sunix, StarTech, or generic serial card) rather than the ASMedia bridge itself.

Hardware ID: To find the exact driver, right-click the device in Device Manager > Properties > Details > Hardware Ids. For the ASM1083 itself, the ID is typically PCI\VEN_1B21&DEV_1080.  Troubleshooting Steps for Windows 10
