HUAWEI Mobile Connect - 3G PC UI Interface (COM14) Driver

The HUAWEI Mobile Connect – 3G PC UI Interface (COM14) driver helps Windows recognize the USB serial interface used by compatible Huawei mobile broadband devices. It allows supported connection-management software to communicate with the device and is useful if the interface appears as an unknown device, shows a warning in Device Manager, or stops responding.

Key Features

• USB serial communication: Provides the driver support needed for compatible software to access the Huawei PC UI interface.
• Device recognition: Helps Windows identify the interface under Ports (COM & LPT) in Device Manager rather than leaving it unrecognized.
• Connection-management support: Enables communication used by compatible Huawei utilities for device control and status information. Other interfaces on the same modem may require separate drivers.
• Legacy Windows compatibility: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the operating systems and architecture supported by the specific driver package.

How to Install HUAWEI Mobile Connect – 3G PC UI Interface (COM14) Driver

1. Check your device and Windows edition. Open Device Manager and locate the Huawei interface. Confirm your Windows version and whether it is 32-bit or 64-bit. If the device is unidentified, compare its hardware IDs with the package’s supported devices.
2. Choose a compatible package. Before starting your HUAWEI Mobile Connect – 3G PC UI Interface (COM14) driver download for Windows, check the package source and compatibility information. Look for a free download from Huawei or a trusted support source, and choose the latest version that explicitly supports your hardware.
3. Install the driver. Extract the downloaded archive if necessary. Run the included installer, or right-click the interface in Device Manager, select Update driver, and browse to the extracted driver folder.
4. Reconnect and verify. Restart Windows if prompted, then reconnect the Huawei device. Check that the interface appears without a warning icon. Windows assigns COM numbers, so your device may appear under a number other than COM14.
5. Test your software. Open your compatible connection utility and confirm that it detects the device. For Windows 10/11 systems, verify support separately: Windows 10 is listed here, but Windows 11 compatibility is not confirmed.

Keep the driver updated when a compatible update addresses detection problems, stability, or software requirements. Use trusted packages, avoid forcing unsupported drivers, and retain a working installer in case you need to restore your previous setup.
