HUAWEI Mobile Connect - PC UI Interface (COM8) Driver

The HUAWEI Mobile Connect – PC UI Interface (COM8) driver lets Windows recognize the PC UI serial interface exposed by compatible Huawei USB mobile broadband devices. It helps Huawei connection software communicate with the device and is useful if this interface appears as an unknown device, shows a warning in Device Manager, or stops responding after a system change.

Key Features

• USB-to-serial communication: Provides access to the Huawei PC UI interface through a Windows COM port, allowing compatible software to exchange control and status information.
• Device recognition: Helps Windows identify the interface correctly instead of listing it as an unrecognized USB component.
• Huawei software support: Enables communication needed by compatible Huawei management utilities. Other modem functions may require additional drivers from the device’s driver package.
• Windows compatibility: Intended for supported configurations running Windows 10, 8.1, 7, Vista, or XP. Match the package to your device model and Windows architecture before installation.

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

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, inspect the interface’s hardware IDs to help identify a matching Huawei package. For Windows 10/11 systems, note that Windows 11 support is not confirmed by the compatibility list above.
2. Choose a compatible package. Before starting your HUAWEI Mobile Connect – PC UI Interface (COM8) driver download for Windows, verify the supported hardware and operating systems. Select the latest version that explicitly supports your configuration; a free download alone does not establish compatibility or authenticity.
3. Prepare the files. Extract the downloaded archive if needed. If the package includes a setup program, run it and follow its instructions, including any prompts about connecting the Huawei device.
4. Install manually if required. Open Device Manager, right-click the affected interface, and choose Update driver or the equivalent option for your Windows version. Browse to the extracted driver folder and complete the installation.
5. Verify detection. Reconnect the device or restart Windows if prompted. Check that the interface appears without a warning icon. Windows may assign a COM number other than COM8; use the assigned port in your connection software where applicable.

Keep the driver updated when a compatible release addresses connection problems or supports system changes. Before you update, confirm the package matches your hardware, and retain a working installer in case you need to restore the previous driver.
