Qualcomm HS-USB NMEA A002 (COM4) Driver

The Qualcomm HS-USB NMEA A002 (COM4) driver helps Windows recognize the USB-connected NMEA serial interface used by compatible Qualcomm-based hardware to transmit positioning data. Listed under Qualcomm Atheros in the USB category, this device may need a driver if it appears as an unknown device in Device Manager or if navigation software cannot access its serial port. Installing a compatible package lets supported applications communicate with the interface, provided the hardware and its firmware offer NMEA output.

Key Features

• USB serial communication: Enables Windows to access the device’s NMEA interface through a virtual COM port.
• Positioning-data access: Allows compatible GPS and navigation applications to read available NMEA messages from the connected hardware.
• Device recognition: Helps resolve missing-driver errors when the package matches your device’s hardware ID.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP; individual packages may support only certain versions and architectures.

How to Install Qualcomm HS-USB NMEA A002 (COM4) Driver

1. Check your system and hardware. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, open the device’s Properties and check Hardware Ids under the Details tab.
2. Choose a matching package. Before starting your Qualcomm HS-USB NMEA A002 (COM4) driver download for Windows, verify that the package supports your hardware ID and operating system. Use a trusted manufacturer-provided free download where available.
3. Extract and install. If the download is an archive, extract it first. Run the included installer, or select Update driver in Device Manager, choose Browse my computer for drivers, and point Windows to the extracted folder.
4. Reconnect and verify. Restart if prompted, then reconnect the hardware. Check that the interface appears under Ports (COM & LPT) without a warning icon. Windows may assign a port number other than COM4.
5. Configure your application. Select the assigned COM port in your navigation or diagnostic software. If you are comparing Windows 10/11 compatibility, note that Windows 11 is not included in the listed supported systems; confirm support with the hardware manufacturer.

Keep the driver updated when a compatible release addresses connection problems or supports your system configuration. Choose the latest version validated for your hardware rather than assuming a newer package is always suitable, and use Device Manager’s rollback option if an update causes problems.
