Asmedia Asm1083 Serial Port Driver Windows 10

Many users confuse the ASM1083 with a UART (Universal Asynchronous Receiver-Transmitter) chip. The ASM1083 is a UART; it is a bridge. The actual serial port controller (often an Oxford Semiconductor, Exar, or Winbond chip) sits behind the bridge. Therefore, the correct driver is usually for the UART chip , not the ASM1083 itself.

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.

Right-click the unrecognized Serial Controller/Port and select . Navigate to the Details tab. Select Hardware Ids from the Property dropdown menu.

Once I have these details, I can point you to the exact driver package you need. Share public link asmedia asm1083 serial port driver windows 10

However, a common frustration among Windows 10 users is the dreaded yellow exclamation mark in Device Manager next to the "ASMedia ASM1083 Serial Port" device. This indicates a driver problem. While this chip is over a decade old, it is still widely used, and getting it to work properly on Windows 10 requires specific knowledge.

The actual PCI Serial Port controller plugged into or routed through that bridge. How to Install the ASM1083 Driver on Windows 10

: If the serial port is built into your motherboard, visit the official support page for your motherboard model (e.g., ASUS Support ) to download the latest "Chipset" or "Serial/I/O" drivers. Many users confuse the ASM1083 with a UART

The ASM1083 isn't actually a serial port itself; it is a . It allows your motherboard's modern PCIe slots to communicate with older 32-bit PCI cards, such as sound cards, capture cards, or—most commonly—multi-port serial (RS-232) cards. Does it need a driver?

A: Yes, the same Windows 10 driver versions (1.16.5.1 or newer) work on Windows 11, but you may face stricter driver signature enforcement.

A: No. It is a PCIe to PCI bridge . Your actual serial port is another chip (e.g., Oxford, Winbond, or Fintek) connected behind this bridge. The ASM1083 simply allows that chip to talk to your modern motherboard. Therefore, the correct driver is usually for the

It takes the PCIe signals from the CPU/chipset and converts them to standard 32-bit PCI signals.

Open Device Manager , find your Serial/COM port, right-click for Properties , go to the Power Management tab, and uncheck “Allow the computer to turn off this device to save power.” 2. Device Manager Shows "Code 10" (Device Cannot Start)

Sometimes the bridge is working, but the serial port itself lacks a driver. If your ASM1083 is connected to a physical COM port header:

The ASM1083 chip does not actually function as a serial port controller on its own. It acts purely as a translator or bridge between your motherboard's modern PCIe lanes and the older PCI slot.

The ASMedia ASM1083 Serial Port Driver is a software component designed to enable communication between a Windows 10 operating system and a serial port device connected via an ASMedia ASM1083 chipset. The driver is essential for ensuring that the serial port functions correctly, allowing users to connect and interact with devices that rely on serial communication, such as modems, printers, and industrial equipment.
