Qualcomm HS-USB NMEA 9091 (COM69) Driver

The Qualcomm HS-USB NMEA 9091 (COM69) driver allows Windows to recognize the device’s USB-based NMEA serial interface, which compatible software can use to receive positioning data from supported hardware. Listed under Qualcomm Atheros in the USB category, this interface may need a driver if it appears as an unknown device, shows a warning in Device Manager, or cannot be accessed by your navigation or diagnostic application.

Key Features

• USB serial communication: Provides the connection between Windows and the device’s NMEA interface, allowing compatible applications to access available positioning messages.
• COM-port access: Exposes the interface as a serial port for software that requires a COM connection. COM69 is the current assignment; Windows may assign a different number after reconnection or reinstallation.
• Legacy Windows support: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility requirements of the individual driver package.
• Device recognition: Helps Windows identify the interface correctly when the matching driver is installed. GPS availability and positioning performance still depend on the underlying hardware, firmware, and reception.

How to Install Qualcomm HS-USB NMEA 9091 (COM69) 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 review its hardware IDs to help select a matching package.
2. Choose a compatible package. Before starting your Qualcomm HS-USB NMEA 9091 (COM69) driver download for Windows, verify the supported operating systems and device IDs. A free download should still come from a trusted source, preferably the hardware manufacturer.
3. Extract and install. Unzip the package if necessary. Run its installer, or select Update driver in Device Manager and browse to the extracted driver folder.
4. Reconnect and verify. Restart Windows if prompted, then reconnect the hardware. Check that the interface appears without a warning icon and note its assigned COM port.
5. Configure your application. Select that COM port in your compatible software. For Windows 10/11 systems, check support separately: Windows 10 is listed here, but Windows 11 compatibility is not confirmed.

Keep the driver updated when your hardware manufacturer provides a compatible release that addresses your needs. Choose the latest version validated for your device and operating system rather than assuming every newer package is suitable. Before an update, retain the working installer or create a restore point so you can recover if communication problems occur.
