This is the ASMedia ASM1083 bridge itself. If Windows shows an error here, it is usually a motherboard chipset or BIOS mapping issue, not a missing driver.
chip. If you see a "PCI Serial Port" with a yellow exclamation mark in your Windows 10 Device Manager, the ASM1083 is simply the bridge that allows a separate serial card to communicate with your modern motherboard. ASMedia Technology Inc. Critical Driver Information itself is "Driver-Free":
This indicates a MosChip/Asix serial controller attached to the bridge. asmedia asm1083 serial port driver windows 10
Disable Above 4G Decoding and Re-Size BAR Support inside your motherboard's Advanced PCIe BIOS settings. Legacy PCI standards rely on strictly bounded 32-bit memory maps, and massive 64-bit addresses will prevent the device from initializing. 3. Data Corruption or Buffer Overruns
| 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). | This is the ASMedia ASM1083 bridge itself
When Windows flags a missing driver for a "PCI Serial Port" and users trace it back to the ASMedia ASM1083, they immediately go searching for an "ASMedia ASM1083 Serial Port Driver."
Windows 10 features robust native support for PCI-to-PCIe bridges. In most scenarios, you do not need a third-party driver specifically from ASMedia for the ASM1083 bridge itself. The operating system handles the bridge automatically, but the serial port attached to it requires manual attention. Step 1: Verify the Device in Device Manager If you see a "PCI Serial Port" with
The ASMedia ASM1083 is not actually a "serial port" chip in the traditional sense; it is a PCI Express-to-PCI Forward Bridge
Since ASMedia is an OEM (Original Equipment Manufacturer), they rarely provide direct consumer downloads. Instead, you should look at:
To get your serial port functioning on Windows 10, follow these steps to ensure both the bridge and the peripheral are recognized. 1. Check Windows Update Windows 10 includes a massive library of legacy drivers. Connect your serial device. Go to . Click Check for updates .
Windows 10 often cuts power to bridge controllers to save energy, which drops active serial connections.
