HUAWEI Mobile Connect - 3G PC UI Interface (COM8) Driver

The HUAWEI Mobile Connect – 3G PC UI Interface (COM8) driver lets Windows recognize the PC UI serial interface exposed by compatible Huawei mobile broadband hardware. It is intended for users whose Huawei modem shows an unknown device, a missing COM port, or a driver warning in Device Manager. This interface helps compatible connection-management software communicate with the modem; it is not, by itself, the complete mobile internet connection setup.

Key Features

• PC UI interface recognition: Identifies the Huawei interface in Windows so compatible software can access its communication port.
• Serial communication support: Enables supported management tools to exchange control and status information with the modem.
• Legacy Windows compatibility: Intended for matching Huawei hardware running Windows 10, 8.1, 7, Vista, or XP, subject to the individual driver package’s requirements.
• Troubleshooting support: Installing the correct package can resolve missing-driver warnings and restore interface detection when driver issues are the cause.

How to Install HUAWEI Mobile Connect – 3G PC UI Interface (COM8) Driver

1. Check the device details. Open Device Manager and locate the Huawei interface under Ports (COM & LPT) or Other devices. In Properties, check its hardware IDs to help identify a matching package. COM8 is a Windows-assigned port number and may differ on another computer.
2. Choose a compatible download. Before starting your HUAWEI Mobile Connect – 3G PC UI Interface (COM8) driver download for Windows, confirm that the package matches your hardware, Windows edition, and 32-bit or 64-bit architecture. Look for a free download from a trusted source.
3. Prepare the files. Extract the archive if necessary and review any included instructions. Close modem-management applications before installation.
4. Install the driver. Run the supplied installer, or select Update driver in Device Manager and browse to the extracted driver folder. Follow the prompts without forcing an incompatible package.
5. Verify detection. Restart Windows if requested, reconnect the modem, and confirm that the interface appears without a warning icon. If your application requires a specific port, check the assigned COM number.

Keep the driver updated when a compatible release addresses a problem you are experiencing. The latest version should match your specific Huawei hardware—not simply have a newer label. For Windows 10/11 systems, check support carefully: Windows 10 is listed here, but Windows 11 compatibility is not confirmed. Avoid an update that does not explicitly support your setup.
