Qualcomm HS-USB NMEA 9025 (COM29) Driver

The Qualcomm HS-USB NMEA 9025 (COM29) 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 carries positioning-related data for applications that read NMEA messages. You may need this driver if the interface appears as an unknown device, shows a warning in Device Manager, or cannot be accessed by your GPS 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 the communication path used to read NMEA messages when the connected hardware and its firmware provide them.
• Device recognition: Helps Windows identify the interface correctly rather than leaving it listed as an unrecognized USB device.
• Legacy Windows support: Intended for compatible installations of Windows 10, 8.1, 7, Vista, and XP; select a package that matches your operating system and architecture.

How to Install Qualcomm HS-USB NMEA 9025 (COM29) Driver

1. Check your system and hardware. Confirm your Windows version and whether it uses a 32-bit or 64-bit architecture. In Device Manager, check the device’s Hardware IDs to help verify package compatibility.
2. Choose a matching package. Before starting your Qualcomm HS-USB NMEA 9025 (COM29) driver download for Windows, review the supported hardware and operating systems. For Windows 10/11 systems, note that Windows 11 support is not established by the compatibility list above.
3. Download and extract the files. Use a trusted source for a free download, and choose the latest version explicitly compatible with your device rather than assuming every newer package will work.
4. Install the driver. Run the included installer, if available. Otherwise, right-click the device in Device Manager, select Update driver or the equivalent option, and browse to the extracted driver folder.
5. Verify the connection. Restart if prompted, reconnect the hardware, and check Device Manager for warnings. Select the assigned COM port in your NMEA application; Windows may assign a number other than COM29.

Keep the driver updated when a compatible release addresses connection problems or improves support for your system. Before you update, retain a working driver package or create a restore point where available, so you can recover if the new version causes issues.
