HUAWEI Mobile Connect - USB Device (COM9) Driver

The HUAWEI Mobile Connect – USB Device (COM9) driver helps Windows recognize and communicate with a compatible Huawei device through its USB serial interface. You may need it when setting up a Huawei modem or mobile broadband device, reinstalling Windows, or troubleshooting an unrecognized COM port in Device Manager.

Key Features

• USB serial communication: Enables compatible software to communicate with the Huawei device through a virtual COM port.
• Device recognition: Helps Windows identify the Mobile Connect interface instead of displaying it as an unknown device or an interface with a missing driver.
• Connection software support: Provides the communication interface that compatible Huawei connection-management or diagnostic software may require.
• Legacy Windows compatibility: Driver packages may support Windows 10, 8.1, 7, Vista, and XP. Select a release that matches your hardware and Windows architecture, as support varies by package.

How to Install HUAWEI Mobile Connect – USB Device (COM9) Driver

1. Identify your system and device. Check 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 if you need to confirm compatibility. COM9 is an assigned port number, not a unique hardware model.
2. Choose a compatible package. Before starting your HUAWEI Mobile Connect – USB Device (COM9) driver download for Windows, verify the package’s supported hardware and operating systems. For Windows 10/11 systems, do not assume Windows 11 compatibility merely because Windows 10 is listed.
3. Download and extract the files. Use a trusted source for a free download, and check the publisher information where available. Extract the archive if the driver is supplied in a compressed folder.
4. Install the driver. Run the included installer and follow its prompts. If no installer is provided, right-click the device in Device Manager, choose Update driver, and browse to the extracted driver folder.
5. Verify the installation. Restart Windows if prompted, then reconnect the Huawei device. Check that its interface appears without a warning icon. Windows may assign a port number other than COM9; configure your application to use the displayed port.

Keep the driver updated when Huawei provides a compatible release that addresses your issue or improves support. Choose the latest version intended for your specific hardware and operating system rather than installing a newer but mismatched package. If an update causes connection problems, use Device Manager’s Roll Back Driver option when available.
