The ASMedia ASM1083 is a widely used PCI Express-to-PCI forward bridge chip. It allows modern motherboards with PCIe slots to interface with legacy PCI devices, such as hardware serial (COM) ports, sound cards, and specialized expansion cards.
Note: Modifying the Windows Registry can be risky. It is essential to proceed with caution and consider backing up your registry before making any changes. This method disables ASPM globally for all devices, which can increase power consumption.
Because it acts as a bridge, Windows 10 handles the ASM1083 using native, built-in drivers. The actual "Serial Port Driver" you need belongs to the specific controller chip sitting on your expansion card (such as a Moschip, Netmos, or Oxford chip), not the ASMedia bridge itself. However, if the bridge driver fails, the serial port will not show up. How to Install and Update the ASM1083 Driver asmedia asm1083 serial port driver windows 10
This guide covers everything you need to know about getting the ASM1083 working on Windows 10, from automatic installation to manual troubleshooting.
While some older drivers exist, Windows 10 often requires generic, updated bridge drivers. The ASMedia ASM1083 is a widely used PCI
A common misconception is that the ASMedia ASM1083 is a serial port controller itself. It is actually a .
The is a widely utilized PCIe to PCI bridge chipset, often found on modern motherboards and expansion cards designed to bridge legacy PCI slots with modern PCIe infrastructure . While primarily handling PCI interfacing, it is frequently associated with "PCI Serial Port" or "PCI Simple Communications Controller" warnings in Windows Device Manager, especially on Windows 10. It is essential to proceed with caution and
), download the driver directly from their official site using the product ID. StarTech.com Common Compatible Drivers
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.
Windows 10 usually configures the ASM1083 automatically as a "Standard PCI-to-PCI Bridge." If you see a yellow exclamation mark next to it in Device Manager, follow these steps to reset or update the driver.
