Mobile Adapter - PC UI Interface (COM13) Driver

The Mobile Adapter – PC UI Interface (COM13) driver helps Windows recognize the PC UI serial interface exposed by a compatible Huawei mobile adapter. It is intended for users whose Huawei connection software cannot communicate with the adapter, or whose Device Manager shows a missing driver or an unrecognized interface.

Key Features

• Enables serial communication: Provides the driver support that compatible Huawei software needs to access the adapter’s PC UI interface.
• Supports device recognition: Helps Windows identify the interface under Ports (COM & LPT), rather than leaving it listed as an unknown device.
• Covers older Windows systems: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Check the individual package for your Windows version and system architecture.
• Helps restore connectivity: Reinstalling a matching driver may resolve communication problems caused by missing or damaged driver files. COM13 is the assigned port number and may change after reconnecting the device.

How to Install Mobile Adapter – PC UI Interface (COM13) Driver

1. Check your device and system. Open Device Manager and locate the Huawei interface. If identification is unclear, check Properties > Details > Hardware Ids. Also confirm whether Windows is 32-bit or 64-bit.
2. Select a compatible package. Before starting your Mobile Adapter – PC UI Interface (COM13) driver download for Windows, verify that the package matches your hardware ID and operating system. Choose a trusted free download without bundled driver-updater utilities.
3. Prepare the files. Extract the downloaded archive if necessary. Close any Huawei connection software before you install the driver.
4. Run the installer or use Device Manager. Follow the package’s setup instructions. If no installer is included, right-click the interface, select the driver update option, and browse to the extracted driver folder.
5. Verify recognition. Restart Windows if prompted, reconnect the adapter, and check that Device Manager shows the interface without a warning icon. If your application requires a port selection, use the COM number currently displayed.

Keep the driver updated when a compatible release addresses an issue you experience. The latest version should match your specific Huawei hardware, not just its displayed name. For Windows 10/11 systems, verify compatibility carefully: Windows 10 is listed here, but Windows 11 support is not confirmed. Before an update, retain the working package so you can reinstall it if needed.
