Qualcomm HS-USB Diagnostics 9025 (COM14) Driver

The Qualcomm HS-USB Diagnostics 9025 (COM14) driver lets Windows recognize a compatible Qualcomm-based device’s USB diagnostic interface and make it available to supported service tools through a virtual COM port. Listed under Qualcomm Atheros in the USB category, this device interface is intended for users and technicians who need diagnostic communication rather than ordinary USB file transfers.

Key Features

• USB diagnostic connectivity: Allows compatible diagnostic software to communicate with the connected device when its diagnostic interface is enabled.
• Virtual serial port access: Exposes the interface as a Windows COM port. COM14 is the assigned port in this device name; the number may differ on another computer.
• Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that explicitly supports your Windows release and system architecture.
• Device recognition: A correctly matched driver can resolve a missing-driver warning for this interface in Device Manager, allowing compatible tools to access it.

How to Install Qualcomm HS-USB Diagnostics 9025 (COM14) Driver

1. Check your system and device. 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 verify that the driver package matches.
2. Choose a compatible package. Before starting your Qualcomm HS-USB Diagnostics 9025 (COM14) driver download for Windows, review the supported systems and package source. If comparing Windows 10/11 options, note that Windows 11 is not included in the listed support information.
3. Download and extract the files. Select a trusted, preferably manufacturer-provided package. A free download should not require a separate paid driver updater. Extract the archive if necessary.
4. Install the driver. Run the included installer, or right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder. Follow the prompts without bypassing Windows security warnings.
5. Verify the connection. Reconnect the device and restart Windows if prompted. Check that the diagnostic interface appears without a warning icon, then select its assigned COM port in your compatible diagnostic tool.

Keep the driver updated when a verified release addresses a connection issue or supports your setup. The latest version is useful only if it matches your device and operating system; review compatibility before you update, and retain the working package in case you need to roll back.
