The HUAWEI Mobile Connect - Extra Control Device is typically a software component or a driver associated with Huawei's mobile broadband devices, such as USB modems, mobile hotspots, or other mobile network adapters. These devices are used for mobile internet connectivity via cellular networks (3G, 4G, or even 5G), and the Extra Control Device is often part of the driver package that helps manage additional features of the device, such as controlling network settings, monitoring connection status, and providing device updates.

This driver may appear when you connect a Huawei mobile broadband device to your Windows PC, and it is necessary for ensuring the device works properly, especially for tasks like:

• Managing mobile data connections.
• Monitoring network status (e.g., signal strength, data usage).
• Configuring network settings and profiles.
