EASY USB to UART Bridge (COM3) Driver

The EASY USB to UART Bridge (COM3) driver enables Windows to recognize Moeller’s USB-to-UART interface and provide a virtual serial port for compatible software. It is intended for users who need to connect compatible Moeller equipment through USB, restore a missing COM port, or resolve a driver-related connection problem.

Key Features

• USB-to-serial communication: Allows compatible applications to communicate with connected equipment through a Windows COM port.
• Device recognition: Helps Windows identify the bridge correctly rather than showing it as an unknown USB device.
• Serial-port access: Makes the interface available in Device Manager, where you can check its status and assigned port number. Although the device name includes COM3, Windows may assign a different number.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Check the individual package for support for your Windows version and system architecture.

How to Install EASY USB to UART Bridge (COM3) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. If the bridge is not recognized, open Device Manager and inspect its hardware IDs to help verify that the driver package matches.
2. Select a compatible package. Before starting an EASY USB to UART Bridge (COM3) driver download for Windows, review the package’s supported systems and source. If choosing a free download, prioritize an official or otherwise trusted source. For Windows 10/11 systems, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here.
3. Prepare the driver files. Extract the downloaded archive if needed. If the package includes an installer, follow its instructions, including any guidance on when to connect the USB interface.
4. Install the driver. Run the supplied installer, or open Device Manager, right-click the affected device, select Update driver, and browse to the extracted driver folder. Menu wording may vary by Windows version.
5. Verify the connection. Reconnect the interface if prompted, then check Device Manager for a COM port without a warning icon. Select that same port in your compatible application and test communication.

Keep the driver updated when a compatible release addresses connection issues or operating-system changes. Before you update, compare the installed driver with the latest version available from a trusted source and review compatibility notes. A newer package is useful only if it supports your specific interface and Windows installation.
