ASMedia ASM1083 is a common bridge chip used on motherboards to convert a PCI Express (PCIe) lane into legacy 32-bit PCI slots. This allows users to use older hardware, such as dedicated serial port (RS-232) cards, on modern systems.

A PCIe serial card containing an ASM1083 bridge + a MosChip 9865 serial controller: ASMedia ASM1083 is a common bridge chip used
The ASM1083 can sometimes struggle with IRQ (Interrupt Request) sharing in Windows 10. If the device shows an "Error Code 12" (not enough resources), try moving the serial card to a different PCI slot if available. Identify the actual serial chip: Right-click the faulty
If you cannot get the ASM1083-based card working reliably on Windows 10, consider these alternatives:
However, some lower-cost cards integrate the UART function into a single ASMedia-designed IC that uses the ASM1083’s PCIe-to-PCI bridge and a built-in serial controller. In these cases, a vendor-specific driver is required.
