Where to Download the Driver
To ensure system stability and security, it is highly recommended to download drivers directly from the hardware manufacturer rather than third-party sites.
Official Manufacturer Support: If you are using an add-on card, visit the SUNIX Support Center or your specific card manufacturer’s site (e.g., StarTech, ASIX) for the most recent WHQL-certified drivers.
Motherboard Chipset Drivers: For ports built directly into your motherboard, download the latest chipset drivers from your PC manufacturer’s site (like HP, Dell, or Lenovo).
Windows Update: Many basic COM/LPT drivers are included in the Windows driver library and can be found under Settings > Windows Update > Advanced options > Optional updates. How to Install COM/LPT Drivers Manually
If the "Ports (COM & LPT)" category is missing from your Device Manager, you may need to add it as "legacy" hardware.
