Look for or ASMedia PCI-to-PCIe Bridge .
The ASMedia ASM1083 is a . Unlike a dedicated sound card or GPU, a bridge chip usually does not require its own driver to function in Windows 10.
Hardware conflicts are common. Before blaming the driver, check your BIOS:
In Device Manager, right-click your Serial Port, select Properties , go to the Power Management tab, and uncheck Allow the computer to turn off this device to save power . asmedia asm1083 serial port driver windows 10
If you are running a legacy PCI (Peripheral Component Interconnect) device on a modern Windows 10 PC—such as an older sound card, a parallel port adapter, or a legacy industrial controller—you may have encountered the chip on your motherboard or add-on PCIe-to-PCI bridge card. This chip acts as a bridge, converting the newer PCI Express interface to the older conventional PCI standard.
Does the device show up as or "Standard PCI-to-PCI Bridge" ?
The most common solution is to disable ASPM entirely in your motherboard's BIOS/UEFI settings. Look for or ASMedia PCI-to-PCIe Bridge
In many modern computer builds, especially those using newer motherboards with legacy PCI slots bridged via PCIe, the is a common component. Users connecting older serial port hardware, legacy audio interfaces, or industrial peripherals via PCI cards often encounter issues where Windows 10 fails to recognize the device, commonly manifesting as a missing "PCI Serial Port" driver or a yellow exclamation mark in Device Manager.
Before troubleshooting drivers, it is crucial to understand the hardware. The ASM1083 is a bridge chip manufactured by ASMedia Technology Inc. Its primary function is protocol conversion:
If the bridge is recognized but your serial ports do not show up, the issue lies with the specific driver of the serial chip welded onto the card, not the ASMedia chip. Hardware conflicts are common
By using the manual "Have Disk" installation method, disabling driver signature enforcement (temporarily), and forcing the Windows 7 driver to load, you can successfully enable your ASM1083 bridge and restore functionality to your serial ports.
For some ASMedia controllers (often USB 3.0 or SATA), reports indicate that the native Windows drivers are more stable than the ASMedia-provided ones. If you are experiencing crashes or instability and suspect an ASMedia driver may be the cause, you can replace it with the standard Microsoft driver.
