ASMedia ASM1083 is not a serial port controller; it is a PCIe-to-PCI bridge designed to allow legacy PCI cards to work in modern PCIe slots. If your Device Manager shows a "PCI Serial Port" with an exclamation mark, it is likely a different component (often part of the Intel Management Engine) that needs a driver, rather than the ASM1083 bridge itself. Driver & Performance Review The ASM1083 is a common solution for "recycling" older hardware, but it has a mixed reputation depending on your specific use case.

ASMedia ASM1083 Serial Port Driver for Windows 10: Installation & Troubleshooting Guide If you have added a legacy serial port card to your modern computer or are using an industrial motherboard, you may have encountered the "ASM1083" chipset. While Windows 10 is excellent at automatically detecting hardware, it occasionally struggles with legacy components like the ASMedia ASM1083 PCI Express to Parallel/Serial Port controller. This guide covers everything you need to know about getting the ASM1083 working on Windows 10, from automatic installation to manual troubleshooting. What is the ASMedia ASM1083? The ASMedia ASM1083 is a bridge chip. It allows older legacy ports (specifically RS-232 Serial Ports and Parallel Printer Ports) to communicate with the modern PCI Express (PCIe) bus. You will typically find this chipset in:
PCIe expansion cards that add a 9-pin serial port to a modern PC. Industrial motherboards that require legacy COM ports for machinery or specialized hardware. Port expansion docks.
Method 1: Windows Automatic Installation (The Easy Way) For many users, Windows 10 and Windows 11 will handle the driver installation automatically without user intervention. asmedia asm1083 serial port driver windows 10
Shut down your PC and install the PCIe card containing the ASM1083 chip. Power on the PC and let Windows load to the desktop. Windows Update should run in the background and silently install a generic driver. Check Device Manager (Right-click Start > Device Manager). Look under Ports (COM & LPT) . You should see a device listed as Communications Port or Serial Port .
Note: If you see a device listed under "Other Devices" with a yellow exclamation mark, Windows failed to find a driver. Proceed to Method 2. Method 2: Using Windows Update (Manual Search) If Windows didn't automatically grab the driver, you can force it to look online.
Open Device Manager . Right-click the unknown device (often labeled ASM1083 or PCI Device under "Other devices"). Select Update driver . Choose Search automatically for drivers . If a driver is found, Windows will install it. ASMedia ASM1083 is not a serial port controller;
Method 3: Microsoft Update Catalog If the automatic search fails, the most reliable source for this specific driver is the Microsoft Update Catalog. The ASM1083 is often treated as a generic system device by Microsoft.
Go to the Microsoft Update Catalog website (catalog.update.microsoft.com). In the search bar, type "ASMedia ASM1083" or simply "ASMedia Serial Port" . Look for a driver designated for Windows 10. It is often packaged as a system update.
Tip: Sometimes the driver is listed under the name "Sunrich," "Sunix," or simply "PCI Serial Port." Asmedia USB 3
Download the cabinet (.cab) file. In Device Manager, right-click the device and select Update Driver > Browse my computer for drivers . Select the folder where you extracted the downloaded .cab file and let Windows install it.
Method 4: Universal Serial Port Drivers Because the ASM1083 adheres to industry standards for serial communication, it often works perfectly with generic Windows drivers.
