Asmedia Asm1083 Serial Port Driver - Windows 10 [repack]

The Ultimate Guide to the ASMedia ASM1083 Serial Port Driver on Windows 10

Introduction: A Bridge to Legacy Hardware

  1. Don't bother with Windows Update. It won't find it.
  2. Look at the chip on your board. Even though the PCIe bridge is the ASM1083, the actual serial port UART chip is usually a secondary chip on the board (commonly a CH340, CH9102, FTDI FT232, or WCH chip).
  3. Download the driver for the SECONDARY chip. In my case, the bridge was ASM1083, but the UART was a CH340. I downloaded the CH340 driver from the WCH website, installed it, and the COM port instantly popped up in Device Manager.
  4. If it truly is a native ASMedia serial: Try going to Device Manager -> Right-click the unknown device -> Update Driver -> "Browse my computer" -> "Let me pick from a list" -> Select Ports (COM & LPT) -> If you see an "ASMedia Serial Port" or similar, select it. If not, try forcing the standard "Communications Port" driver.

The "Real" Driver: If you are trying to get a Serial Port to work, you likely need the driver for the I/O Controller chip on the expansion card (e.g., MosChip, NetMos, or Oxford), not the ASMedia bridge itself. 📂 How to Install and Update asmedia asm1083 serial port driver windows 10

Disable CSM: Try toggling "Compatibility Support Module" in your BIOS settings. The Ultimate Guide to the ASMedia ASM1083 Serial

Since the ASM1083 is just a "bridge," the yellow exclamation mark in Device Manager is often a legacy card (like an old modem or serial expansion card) plugged into a PCI slot. Right-click the error in Device Manager. Select Properties > Details. Choose Hardware Ids from the dropdown. Don't bother with Windows Update

  1. Native PCIe Serial Card – Use a card based on a modern chip like the EXAR XR17V358 or MosChip MCS9922, which have official Windows 10 drivers.
  2. USB-to-Serial Adapter – FTDI FT232R or Silicon Labs CP210x-based adapters are fully supported in Windows 10. (Note: Not ideal for low-latency or industrial use.)
  3. Virtual Serial Port Software – If you only need data transfer between applications, virtual COM port emulators (e.g., com0com) can bypass hardware entirely.

In conclusion, the ASMedia ASM1083 Serial Port Driver is a reliable and efficient software component that enables serial port communication on Windows 10 systems. The driver's ease of installation, compatibility with various devices, and stable performance make it a suitable choice for users who require serial port connectivity. While some users may encounter compatibility issues with specific devices or software applications, the ASMedia ASM1083 Serial Port Driver provides a solid foundation for serial port communication on Windows 10.
