HUAWEI Mobile Connect - 3G PC UI Interface (COM17) Driver

The HUAWEI Mobile Connect – 3G PC UI Interface (COM17) driver lets Windows recognize and communicate with the PC UI serial interface exposed by a compatible Huawei USB modem. It is useful if Device Manager shows an unknown device, the interface has a warning icon, or Huawei connection software cannot detect the modem’s control port.

Key Features

• USB interface recognition: Helps Windows identify the Huawei Mobile Connect PC UI interface rather than leaving it listed as an unrecognized device.
• Serial port communication: Enables compatible software to communicate with the modem through a virtual COM port. COM17 is the port assignment on your system, not a separate modem model.
• Connection software support: Provides an interface that Huawei modem utilities may use for device management and status communication; mobile data connections may require additional modem drivers.
• Legacy Windows support: Intended for compatible configurations running Windows 10, 8.1, 7, Vista, or XP, subject to the individual driver package’s requirements.

How to Install HUAWEI Mobile Connect – 3G PC UI Interface (COM17) Driver

1. Check your device and Windows edition. Open Device Manager, locate the Huawei interface, and check its hardware IDs under Properties > Details. Confirm whether your Windows installation is 32-bit or 64-bit.
2. Choose a matching package. Before starting the HUAWEI Mobile Connect – 3G PC UI Interface (COM17) driver download for Windows, verify that the package supports your hardware IDs and operating system. Use a trusted source for a free download, and choose the latest version that explicitly supports your configuration.
3. Extract and install. Unzip the downloaded archive if necessary. Run the supplied installer, or open the device’s properties in Device Manager and use the driver update option to browse to the extracted driver folder.
4. Reconnect and verify. Restart Windows if prompted, reconnect the modem, and check that the interface appears without a warning icon. Windows may assign a COM number other than COM17.
5. Test your software. Open your compatible Huawei utility and confirm that it detects the modem. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed as supported here, but Windows 11 support is not confirmed.

Keep the driver updated when a compatible release addresses detection, stability, or communication issues. Before you update a working installation, retain the existing driver package or create a restore point so you can roll back if needed.
