Qualcomm HS-USB Android DIAG 9018 (COM107) Driver

The Qualcomm HS-USB Android DIAG 9018 (COM107) driver lets Windows communicate with the diagnostic interface exposed by a compatible Qualcomm-based Android device over USB. Listed under Qualcomm Atheros in the USB category, this interface is primarily useful for technicians and advanced users working with diagnostic software rather than everyday file transfers.

Key Features

• Diagnostic communication: Enables compatible service tools to access the device’s diagnostic interface when the correct USB mode is active.
• COM-port recognition: Allows Windows to identify the interface as a serial port. COM107 is the assigned port number on this system; another computer may assign a different number.
• Support for listed Windows versions: Intended for Windows 10, 8.1, 7, Vista, and XP, provided the selected package matches your operating system and processor architecture.
• Device identification: Helps resolve missing-driver entries when the package supports the connected device’s hardware ID. It does not replace separate ADB, fastboot, or file-transfer drivers.

How to Install Qualcomm HS-USB Android DIAG 9018 (COM107) Driver

1. Check the device and system. Open Device Manager and locate the diagnostic interface, which may appear under Ports (COM & LPT) or Other devices. Check its hardware IDs under Properties > Details, and confirm whether Windows is 32-bit or 64-bit.
2. Choose a compatible package. Before starting a Qualcomm HS-USB Android DIAG 9018 (COM107) driver download for Windows, verify the supported hardware IDs and operating systems. Select the latest version that explicitly supports your setup. A free download label alone does not establish compatibility or authenticity.
3. Prepare the USB connection. Connect the device with a reliable data cable. If diagnostic mode is required, enable it only through the device manufacturer’s documented procedure.
4. Install the driver. Extract the downloaded archive if necessary. Run its trusted installer, or select Update driver in Device Manager and browse to the extracted driver folder. Follow the prompts without bypassing Windows security warnings.
5. Verify detection. Reconnect the device or restart Windows if requested. Confirm that the diagnostic interface appears without a warning icon, then select its assigned COM port in your compatible diagnostic application.

Keep the driver updated when a compatible release addresses connection problems or improves support for your tools. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed here, but Windows 11 support is not confirmed. Before an update, retain a working driver copy or create a restore point so you can recover if communication stops working.
