HUAWEI Mobile Connect - Bluetooth Interface (COM73) Driver

The HUAWEI Mobile Connect – Bluetooth Interface (COM73) driver helps Windows recognize and communicate with the Bluetooth-related interface exposed by a compatible Huawei USB device. You may need it if this interface appears as an unknown device, shows a warning in Device Manager, or stops working after a Windows reinstall.

Key Features

• Device recognition: Enables Windows to identify the Huawei Mobile Connect interface rather than leaving it listed as an unsupported device.
• Serial interface access: Provides the driver support needed for compatible software to communicate through the assigned COM port.
• Legacy Windows compatibility: Intended for supported configurations running Windows 10, Windows 8.1, Windows 7, Windows Vista, or Windows XP, depending on the driver package.
• Troubleshooting support: Installing the correct package can help resolve missing-driver errors and restore communication with the interface.

COM73 is a Windows-assigned port number, not a separate hardware model. Match the driver to your device’s hardware IDs and operating system rather than relying on the port number alone. This driver should not be assumed to work as a universal Bluetooth adapter driver.

How to Install HUAWEI Mobile Connect – Bluetooth Interface (COM73) Driver

1. Check your system. Confirm your Windows version and whether it uses a 32-bit or 64-bit architecture. In Device Manager, open the interface’s Properties and check Hardware IDs under the Details tab.
2. Choose a compatible package. Before starting a HUAWEI Mobile Connect – Bluetooth Interface (COM73) driver download for Windows, verify the supported operating systems and hardware IDs. Select the latest version that explicitly supports your configuration.
3. Download and extract. Use a trusted source for a free download, scan the package with your security software, and extract it if it comes in an archive.
4. Install the driver. Run the included installer, if provided. Otherwise, right-click the interface in Device Manager, select Update driver, and browse to the extracted driver folder.
5. Verify the result. Restart if prompted, reconnect the Huawei device, and check that Device Manager no longer displays a warning. Confirm that your connection software uses the currently assigned COM port.

Keep the driver updated when a compatible release addresses connection problems or system changes. For Windows 10/11 systems, check support carefully: Windows 10 is listed here, but Windows 11 compatibility is not confirmed. Avoid forcing an unsupported update if your current driver works reliably.
