Huawei USB AT Device (COM10) Driver

The Huawei USB AT Device (COM10) driver lets Windows recognize the AT-command interface on compatible Huawei USB modems and mobile broadband devices. It is useful if your device appears as an unknown device, shows a warning in Device Manager, or cannot communicate with software that uses its serial control port. COM10 is the port number assigned by Windows; it may differ when you reconnect the device or use another computer.

Key Features

• Enables serial communication over USB so compatible applications can send AT commands to the Huawei device.
• Provides the control interface used by supported modem utilities for tasks such as checking device status and configuring connection settings.
• Helps Windows identify the USB AT interface and display its assigned COM port in Device Manager.
• Supports compatible driver packages for Windows 10, 8.1, 7, Vista, and XP; the correct package depends on your hardware model and Windows architecture.

How to Install Huawei USB AT Device (COM10) Driver

1. Identify your Huawei hardware model and check whether your Windows installation is 32-bit or 64-bit. Before choosing a Huawei USB AT Device (COM10) driver download for Windows, confirm that the package supports both.
2. Obtain the matching driver from a trusted source, preferably Huawei or your device provider. When choosing a free download, check its publisher and compatibility rather than assuming the latest version supports every older modem.
3. Extract the downloaded archive if necessary. If the package includes an installer, run it and follow its instructions, connecting or disconnecting the device only when prompted.
4. For manual installation, open Device Manager, locate the Huawei AT interface or unidentified device, and choose the option to update its driver. Browse to the extracted driver folder and allow Windows to install the matching files.
5. Restart the computer if requested, then check Device Manager for warnings. Confirm the assigned COM port and select that same port in your modem utility or AT-command application.

Keep the driver updated when a compatible release addresses connection problems or improves reliability, but avoid replacing a working driver with an unrelated package. For Windows 10/11 systems, verify support separately: Windows 10 is listed for this device, while Windows 11 compatibility is not confirmed here. An update to the AT interface alone may not resolve issues with separate modem or network interfaces.
