Lab126 HS-USB NMEA 0800 (COM43) Driver

The Lab126 HS-USB NMEA 0800 (COM43) driver helps Windows recognize the device’s USB-connected NMEA serial interface so compatible software can communicate with it through a COM port. Associated with Qualcomm Atheros hardware, this driver is intended for users whose device appears as unrecognized hardware, shows a driver warning, or cannot be accessed by an application that reads NMEA data.

Key Features

• USB serial communication: Provides access to the device’s NMEA interface, commonly used to carry navigation-related messages to compatible applications.
• COM-port recognition: Allows Windows to expose the interface as a serial port. COM43 is the port shown in this device name, but Windows may assign a different number after installation.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Compatibility depends on the specific driver package and whether your system uses a 32-bit or 64-bit edition.
• Driver troubleshooting: Installing a matching package may resolve missing-driver errors and restore communication when an incorrect or incomplete driver is installed.

How to Install Lab126 HS-USB NMEA 0800 (COM43) Driver

1. Verify your hardware. Open Device Manager, locate the device, and check Properties > Details > Hardware Ids. Match these identifiers against the driver package’s supported devices rather than relying only on the displayed name.
2. Choose a compatible package. Before starting a Lab126 HS-USB NMEA 0800 (COM43) driver download for Windows, confirm your Windows edition and system architecture. For Windows 10/11 systems, note that Windows 11 is not included in the supplied support list; do not assume compatibility.
3. Download and extract the files. If a free download is offered, verify its source and check the package for a valid digital signature where available. Extract compressed files before proceeding.
4. Install the driver. Run the included installer, if provided, or select Update driver in Device Manager and browse to the extracted folder. Follow the prompts without bypassing Windows security warnings.
5. Check the connection. Restart if prompted, reconnect the device, and confirm that Device Manager shows no warning icon. Select the assigned COM port in your application.

Keep the driver updated when a verified release addresses a problem or improves compatibility with your setup. Choose the latest version that explicitly supports your hardware and operating system, and retain a working driver or restore point before an update.
