Qualcomm HS-USB NMEA 9025 (COM18) Driver

The Qualcomm HS-USB NMEA 9025 (COM18) driver lets Windows communicate with the NMEA serial interface exposed by compatible Qualcomm-based USB hardware. Listed under Qualcomm Atheros in the USB category, this device typically provides positioning-related data to compatible applications through a virtual COM port. You may need the driver if the interface appears as an unknown device, shows a warning in Device Manager, or cannot be accessed by your navigation or diagnostic software.

Key Features

• USB-to-serial communication: Enables compatible software to access the device’s NMEA interface through a Windows COM port.
• Positioning data access: Supports communication with applications that read NMEA messages, where the connected hardware and firmware provide that output.
• Device recognition: Helps Windows identify the interface correctly rather than leaving it listed as an unrecognized USB device.
• Legacy Windows support: Intended for compatible configurations running Windows 10, 8.1, 7, Vista, or XP. Check the individual package for supported editions and 32-bit or 64-bit requirements.

How to Install Qualcomm HS-USB NMEA 9025 (COM18) Driver

1. Check your system and device. Confirm your Windows version and system architecture. In Device Manager, open the device’s Properties and check its hardware IDs to help identify a matching package. COM18 is an assigned port number, not a unique hardware identifier.
2. Choose a compatible package. Before starting a Qualcomm HS-USB NMEA 9025 (COM18) driver download for Windows, verify that the package supports your hardware and operating system. Prefer a trusted manufacturer source when choosing a free download.
3. Extract and install the files. If the package includes an installer, follow its instructions. Otherwise, extract the archive, right-click the device in Device Manager, select Update driver, and choose the option to browse your computer for drivers.
4. Reconnect and verify. Restart Windows if prompted, then reconnect the hardware. Confirm that the interface appears without a warning icon and note its assigned COM port, which may differ from COM18.
5. Configure your application. Select the matching port in your NMEA-compatible software. For Windows 10/11 systems, verify support separately: Windows 10 is listed here, but Windows 11 compatibility is not confirmed.

Keep the driver updated when a compatible release addresses connection problems or operating-system changes. Choose the latest version approved for your specific hardware rather than assuming a newer package will work better, and keep a copy of the working driver before applying an update.
