Qualcomm HS-USB NMEA 250D (COM7) Driver

The Qualcomm HS-USB NMEA 250D (COM7) driver allows Windows to 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 a connection for GPS/GNSS positioning messages rather than general USB storage or networking. 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 positioning 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 receive NMEA messages when the hardware and its firmware provide location data.
• Device recognition: Helps Windows identify the interface correctly instead of leaving it listed as an unrecognized USB device.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. The correct package must match your Windows version and system architecture.

How to Install Qualcomm HS-USB NMEA 250D (COM7) 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 its Hardware IDs to help verify the package matches.
2. Select a compatible package. Before starting your Qualcomm HS-USB NMEA 250D (COM7) driver download for Windows, review the supported systems and device identifiers. Choose the latest version approved for your hardware; a free download label alone does not establish compatibility or safety.
3. Extract and install. If the package includes an installer, follow its instructions. Otherwise, extract the files, right-click the device in Device Manager, select Update driver, 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. Windows may assign a port other than COM7, so select the actual port shown in your application.
5. Check application access. Open your compatible positioning software and select the assigned COM port. Location output also depends on device configuration, GNSS availability, and application settings.

Keep the driver updated when the hardware manufacturer provides a compatible release that addresses your needs. For Windows 10/11 systems, verify support separately: Windows 10 is listed for this device, but Windows 11 compatibility is not confirmed here. Before an update, retain a working driver package so you can restore it if necessary.
