HUAWEI Mobile Connect - USB Device (COM4) Driver

The HUAWEI Mobile Connect – USB Device (COM4) driver helps Windows recognize and communicate with the USB serial interface on compatible Huawei mobile broadband hardware. It is intended for users whose connected Huawei device appears with a missing driver, displays a warning in Device Manager, or is not detected by connection software.

Key Features

• USB serial communication: Enables compatible Huawei software to communicate with the device through a Windows COM port.
• Device recognition: Helps Windows identify the Huawei Mobile Connect interface instead of listing it as an unknown device.
• Legacy Windows support: Intended for supported configurations running Windows 10, 8.1, 7, Vista, or XP; compatibility depends on the specific driver package and hardware.
• Connection software integration: Provides an interface that compatible modem-management applications can use to access the device. Additional drivers may be required for other modem functions.

How to Install HUAWEI Mobile Connect – USB Device (COM4) Driver

1. Check your device and Windows edition. Open Device Manager and locate the Huawei interface, typically 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 matching package. Before starting a HUAWEI Mobile Connect – USB Device (COM4) driver download for Windows, verify that the package supports your hardware IDs and operating system. Select the latest version that explicitly supports your configuration.
3. Download and prepare the files. Use a trusted free download source, preferably Huawei or your hardware provider. Extract the archive if necessary, and check any included installation instructions.
4. Install the driver. Run the supplied installer, or right-click the device in Device Manager, choose Update driver, and browse to the extracted driver folder. Avoid unsigned or unverified packages.
5. Reconnect and verify. Restart Windows if prompted, reconnect the device, and confirm that Device Manager shows no warning icon. Windows may assign a port number other than COM4; configure your connection software to use the assigned port.

Keep the driver updated when a compatible release addresses detection, stability, or connection issues. For Windows 10/11 systems, check support carefully: Windows 10 is listed here, but Windows 11 compatibility is not confirmed. Before an update, retain a working driver package or create a restore point so you can recover if needed.
