SMSC USB Serial Port Driver

The SMSC USB Serial Port driver enables Windows to communicate with the USB serial interface from Standard Microsystems, allowing compatible software to access connected serial equipment through a COM port. You may need it when setting up the device for the first time, reinstalling Windows, or troubleshooting an unrecognized USB serial connection.

Key Features

• USB-to-serial communication: Provides the driver support needed for compatible applications to exchange data with connected serial hardware.
• COM port access: Allows serial communication software to use the device through a Windows COM port, which you can check in Device Manager.
• Windows compatibility: Supported operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and system architecture.
• Device recognition: Helps Windows identify the interface correctly when the appropriate driver is missing or an incompatible driver is installed.

How to Install SMSC USB Serial Port Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. If the device appears as unknown hardware, check its hardware IDs in Device Manager to help verify the correct package.
2. Choose a compatible download. Before selecting an SMSC USB Serial Port driver download for Windows, review the package’s supported systems and device details. A “free download” label alone does not establish compatibility or authenticity; use a trusted source.
3. Extract and install the driver. Unzip the downloaded archive if necessary. Run the included installer, or open Device Manager, right-click the relevant device, select Update driver, and browse to the extracted driver folder.
4. Follow the installation prompts. Connect or reconnect the device when instructed. Restart Windows if the installer requests it.
5. Verify the connection. Open Device Manager and look under Ports (COM & LPT). Confirm that the device has no warning icon, then select its assigned COM port in your serial application.

Keep the driver updated when a compatible release addresses a problem or adds needed support, rather than replacing a working setup unnecessarily. Check that the latest version supports your exact hardware and operating system before you update. For Windows 10/11 systems, note that Windows 10 is listed as supported here, while Windows 11 compatibility must be verified separately.
