How to Fix ASMedia ASM1083 Serial Port Driver Issues on Windows 10

If you’ve recently added a legacy PCI card to your modern PC, you might have noticed a pesky "PCI Serial Port" with a yellow exclamation mark in your Device Manager. More often than not, this is tied to the ASMedia ASM1083, a popular PCIe-to-PCI bridge controller used to bridge the gap between old hardware and new motherboards.

Here is everything you need to know about getting the ASM1083 working smoothly on Windows 10. What is the ASMedia ASM1083?

The ASM1083 isn't actually a serial port itself; it is a bridge chip. 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?

Technically, the ASM1083 chip itself is often recognized natively by Windows 10 as a "PCI-to-PCI Bridge" and usually requires no specific driver for the adapter hardware.

However, the serial port card plugged into that bridge does need a driver. If you see a "PCI Serial Port" error, Windows is actually asking for the driver of the serial card (e.g., a card using a Moschip, NetMos, or Sunix controller) that is sitting behind the ASMedia bridge. Step-by-Step: Installing the Driver on Windows 10 1. Identify the Hardware ID

Before downloading random files, find out exactly what your serial port is. Right-click the Start button and select Device Manager. Find the entry under Other Devices labeled PCI Serial Port.

Right-click it, select Properties, and go to the Details tab.

Select Hardware Ids from the dropdown. You’ll see a string like PCI\VEN_1B21&DEV_1080 (which is the ASMedia bridge) or a different ID for the serial controller itself. 2. Where to Download asmedia asm1083 serial port driver windows 10

Since ASMedia is an OEM (Original Equipment Manufacturer), they rarely provide direct consumer downloads. Instead, you should look at:

Motherboard Manufacturer: Check the support page for your motherboard (ASUS, Gigabyte, MSI) under "Chipset" or "Others".

Expansion Card Brand: If you bought a standalone PCIe-to-PCI card, check the brand’s website (e.g., StarTech or Syba).

Driver Repositories: Reliable third-party sites like Station-Drivers or DriverScape often host WHQL-certified ASMedia bridge and controller drivers. 3. Manual Installation (The "Have Disk" Method)

If the installer doesn't work, try this manual method which often bypasses "Incompatible OS" errors: Extract your downloaded driver folder.

In Device Manager, right-click the PCI Serial Port and choose Update Driver. Select Browse my computer for drivers.

Click Let me pick from a list of available drivers on my computer. Select Show All Devices, then click Have Disk.

Browse to the folder where you extracted the driver and look for the .inf file. Common Issues: Spurious Interrupts How to Fix ASMedia ASM1083 Serial Port Driver

The ASM1083 is known for occasional "interrupt handling" bugs. If your serial device is connected but data is corrupted or the system lags, it may be due to how the bridge handles signals. Ensure you are using a version of Windows 10 newer than Build 10586, as Microsoft released updates specifically to improve bridge driver stability.

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 USB 3.0 drivers installation failure.

Troubleshooting Common Installation Errors

Issue 3: COM Port Number Not Retained After Reboot

  • Fix: In Device Manager, go to the serial port's properties → Port Settings → Advanced → COM Port Number → select a low, unused number (e.g., COM3 or COM4). Click OK.

7. Recommendations

| Scenario | Action | | :--- | :--- | | ASM1083 appears in Device Manager with no error | Do nothing. It is working correctly. | | ASM1083 has a yellow exclamation | Update BIOS, reset CMOS, or reinstall chipset drivers. The device itself does not need a driver. | | A COM port (Serial Port) is not working | Identify the actual serial controller's VEN/DEV ID and download its specific Windows 10 driver. | | You are installing a PCIe-to-PCI serial card | Let Windows 10 install the serial driver automatically via Windows Update (often required). |

Issue 1: Code 10 (Device Cannot Start)

  • Cause: Driver conflict or resource allocation (IRQ/memory).
  • Fix: Disable legacy COM ports in BIOS (if present). Update motherboard chipset drivers. Try a different PCIe slot.

Part 9: Frequently Asked Questions

Q: Do I need the ASMedia ASM1083 driver at all? A: Not if you have no devices connected to the PCI slots that are routed through this bridge. However, Windows will still show an error unless you disable the device or hide it.

Q: Will this driver work on Windows 11? 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. Troubleshooting Common Installation Errors Issue 3: COM Port

Q: Why does it say "Serial Port" when I'm using a PCI sound card? A: The chip includes a separate serial controller function. The sound card uses the PCI bridge function, which is a different logical device. The serial port driver error does not affect other PCI devices unless the bridge fails entirely.

Q: My PC freezes when scanning for hardware changes. Help? A: This is a known issue with the ASM1083 on certain BIOS/UEFI systems. Try moving your PCI card to a different slot. Also, update your motherboard's BIOS to the latest version.

Conclusion

The ASMedia ASM1083 Serial Port driver on Windows 10 is a classic example of legacy hardware clashing with modern operating systems. While frustrating, the problem is solvable with the right driver version and a few system tweaks.

Recap of best practices:

  • Always download the driver from a trusted source (Microsoft Update Catalog or motherboard OEM).
  • Use the manual "Have Disk" installation method.
  • Disable driver signature enforcement if necessary (temporarily).
  • If all else fails, disable the serial port function via registry to stop error notifications.

Your legacy PCI hardware—whether it is a vintage audio card, a parallel port for an engraving machine, or a specialized data acquisition card—can still live on in a Windows 10 PC, thanks to the ASM1083 bridge, provided you master its quirky driver requirements.

Now go ahead and get that yellow exclamation mark out of your Device Manager for good.

1. Introduction: What is the ASMedia ASM1083?

The ASMedia ASM1083 is a PCIe to PCI bridge chip. Its primary function is to convert a modern PCI Express (PCIe) interface into a legacy PCI (Peripheral Component Interconnect) bus. This chip is commonly found on motherboards (especially from the late 2000s to mid-2010s) that needed to retain support for older PCI cards—such as sound cards, network cards, or serial/parallel port cards—while using a newer PCIe-based chipset.

One specific implementation of the ASM1083 is on PCIe-based multi-I/O cards that provide legacy serial (RS-232) ports. These cards are still used in industrial, scientific, and embedded systems environments where legacy serial devices (barcode scanners, CNC machines, laboratory instruments, serial mice, etc.) must interface with a modern Windows 10 PC.

Thus, when users search for the "ASMedia ASM1083 serial port driver Windows 10," they are typically looking for the software that allows a PCIe-to-serial adapter card (powered by the ASM1083 bridge) to function correctly under Microsoft’s latest operating system.
