Because the ASM1083 is a standard PCI Express-to-PCI bridge, Windows 10 includes native, built-in drivers for it. In 95% of cases, you do not need to download a third-party driver from ASMedia. Step 1: Use Windows Native Drivers
If your motherboard has an integrated ASM1083, go to the support page for your exact model. Search for "PCI Bridge Driver" or "Chipset Driver". For example:

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. asmedia asm1083 serial port driver windows 10
Many motherboards from ASUS, Gigabyte, MSI, and others from the late 2000s to early 2010s integrate this chip. You will also find it on standalone PCIe-to-PCI adapter cards.
Developer and programming notes
If you are still having issues with the Asmedia ASM1083 driver on Windows 10, please tell me: Are you using a or server ? What is the exact model of your motherboard ? What specific serial device are you trying to connect? Because the ASM1083 is a standard PCI Express-to-PCI
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.
For standard diagnostic and configuration tasks, a high-quality USB-to-RS232 adapter utilizing an FTDI or Prolific chip offers superior stability and plug-and-play compatibility on Windows 10.
In most scenarios, for the ASM1083 chip itself. Search for "PCI Bridge Driver" or "Chipset Driver"
This indicates a MosChip/Asix serial controller attached to the bridge.
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 is a unique PCIe to PCI bridge chip. It allows older PCI (Peripheral Component Interconnect) cards—such as legacy serial ports, industrial I/O cards, or older sound cards—to function in modern motherboards that only feature PCI Express (PCIe) slots. However, Windows 10 does not always natively recognize this bridge, leading to "Code 28" errors, yellow exclamation marks in Device Manager, or complete non-functionality of your serial devices.
