Struggling with an ASMedia ASM1083 Serial Port adapter on Windows 10? 🤬
Here’s the secret: The ASM1083 is just the PCIe bridge chip. The actual serial driver you need depends on the smaller UART chip next to it (usually a CH340, FTDI, or Prolific).
Find that secondary chip number, Google "[Chip Number] Windows 10 driver," install it, and your COM port will magically appear. Don't waste time looking for an "ASM1083 Serial Driver" because it doesn't exist!

Title: ASMedia ASM1083 Serial Port Driver for Windows 10 – Solution & Fix
Body: The ASMedia ASM1083 is a PCIe to PCI bridge chip, not a traditional standalone serial port controller. Windows 10 often mislabels its generic driver requirement as a "Serial Port" device in Device Manager when the correct PCI Bridge driver is missing.
Important Note: There is no specific "ASM1083 Serial Port" driver from ASMedia for Windows 10. The chip typically uses Microsoft’s inbox PCI-to-PCI bridge driver.
How to fix it in Windows 10:
Alternatively, install your motherboard’s chipset drivers (Intel/AMD) – they will correctly identify the bridge without a dedicated ASM1083 package. Do not download "ASM1083 drivers" from third-party sites; they are often malware.
Option 2: Short Web Description (e.g., for a driver listing or blog)
ASMedia ASM1083 Windows 10 Driver Information
The ASM1083 is a PCI Express to PCI bridge, not a native serial port. Windows 10 typically manages this device via its native PCI-to-PCI bridge driver. If you see a "Serial Port" error, manually assign the "Microsoft PCI-to-PCI Bridge" driver via Device Manager. No official ASM1083 driver package exists for Windows 10; rely on your system chipset drivers instead. Avoid unofficial driver updaters.
Option 3: Quick user-to-user answer (Reddit/Forum reply)
"The ASM1083 isn’t really a serial port chip – it’s a PCIe-to-PCI bridge. Windows 10 doesn’t have a specific 'ASM1083 serial port driver' because that’s a misidentification. Go to Device Manager, right-click the problem device, pick 'Update driver' → 'Browse my computer' → 'Let me pick' → choose 'PCI-to-PCI Bridge' from the list. That should clear the error. No need to hunt for an ASMedia download."

Conclusion The ASMedia ASM1083 serial port driver for Windows 10 is essential for enabling serial communication on systems equipped with this chip. By following the installation and update procedures, users can ensure their device functions correctly and efficiently.
The ASMedia ASM1083 is not a serial port controller itself, but rather a PCI Express-to-PCI bridge chip. It is commonly found on motherboards or expansion cards to allow legacy PCI devices—such as older sound cards or industrial serial port cards—to work on modern PCIe-only systems.
If you see a "PCI Serial Port" error in Windows 10 related to this chip, it usually means the operating system needs a driver for the specific peripheral (the serial card) plugged into that bridge, rather than the ASM1083 chip itself. Driver Requirements for Windows 10
Bridge Chip (ASM1083): In most cases, Windows 10 provides native (inbox) support for the ASM1083 bridge. It typically appears in Device Manager under "System devices" as a "PCI standard PCI-to-PCI bridge". No third-party driver is usually required for the bridge to function.
The Serial Port Device: The actual serial port functionality comes from a separate controller (e.g., from NetMOS, MosChip, or Oxford) that sits behind the ASM1083 bridge. You must identify the hardware ID of that specific serial device to find the correct driver. Troubleshooting "Missing Driver" Errors
If Device Manager shows a yellow exclamation mark for a "PCI Serial Port": ASM1083-PCIe to PCI Bridge Controller
You will see "Windows cannot verify the digital signature of this driver" on 64-bit Windows 10.
Permanent Fix (Not recommended for security):
Better Fix (Use test mode permanently): Run Command Prompt as Admin:
bcdedit /set testsigning on
Reboot. You will see "Test Mode" in the corner – now install the driver. After success, run bcdedit /set testsigning off and reboot.
No driver download is required for the ASMedia ASM1083 under Windows 10. The operating system fully supports it via native bus drivers. Any perceived "missing driver" for a serial port is actually for a different chip that connects through the ASM1083 bridge. Focus troubleshooting on the serial port controller itself, not the bridge chip.
If you need further assistance, please provide the Hardware IDs (VEN/DEV) from Device Manager for the malfunctioning device.
How to Fix ASMedia ASM1083 Serial Port Driver Issues on Windows 10 Hardware and device identification
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
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
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.
