Huawei USB AT Device (COM24) Driver

The Huawei USB AT Device (COM24) driver enables Windows to communicate with the AT-command interface exposed by compatible Huawei USB hardware, such as a modem. You may need it when setting up the device, restoring a missing serial connection, or troubleshooting an unrecognized Huawei entry in Device Manager. COM24 identifies the assigned serial port; the port number can change when the device is reconnected or installed on another computer.

Key Features

• Enables AT-command communication between compatible Huawei hardware and applications used for device configuration or diagnostics.
• Makes the device’s USB serial interface available through a Windows COM port.
• Helps resolve missing-driver warnings or recognition problems when the correct package matches your hardware.
• Supports installation on Windows 10, 8.1, 7, Vista, and XP when you select a package intended for your operating system and architecture.

How to Install Huawei USB AT Device (COM24) Driver

1. Identify your device and Windows version. Open Device Manager and locate the Huawei interface, which may appear under Ports (COM & LPT) or Other devices. Check its Hardware Ids under Properties > Details, and confirm whether Windows is 32-bit or 64-bit.
2. Choose a compatible package. Before starting your Huawei USB AT Device (COM24) driver download for Windows, compare the package’s supported hardware and operating systems with your computer. Select the latest version that explicitly supports your device—not simply the newest available release. For Windows 10/11 systems, verify support separately: Windows 11 is not included in the listed supported operating systems.
3. Download and extract the files. Use a trusted source for a free download, and scan the downloaded package before opening it. Extract compressed files to an easy-to-find folder.
4. Install the driver. Run the included installer if provided. Otherwise, right-click the device in Device Manager, choose Update driver, and browse to the extracted driver folder. Follow the prompts without bypassing driver-signature warnings.
5. Verify the connection. Restart Windows if requested, reconnect the Huawei device, and check that Device Manager shows no warning icon. In your communication software, select the COM port currently assigned to the device.

Keep the driver updated when a compatible update addresses connection issues or improves support for your Windows installation. If the device already works reliably, review release notes before replacing its driver, and keep the previous working package available in case you need to roll back.
