ZTE CMCC DIAG Interface (COM62) Driver

The ZTE CMCC DIAG Interface (COM62) driver allows Windows to recognize the diagnostic USB interface exposed by a compatible ZTE device and make it available as a serial COM port. It is intended for users and technicians who need compatible diagnostic software to communicate with the device, particularly when Windows shows an unrecognized interface or a missing-driver warning.

Key Features

• Diagnostic communication: Provides access to the device’s diagnostic interface for supported service and troubleshooting tools. It is not a general-purpose driver for file transfers or internet access.
• COM-port recognition: Enables Windows to identify the interface as a serial port. COM62 is the assigned port number on this system; another computer may assign a different number.
• USB interface support: Helps Windows associate the connected ZTE diagnostic interface with the appropriate driver rather than leaving it listed as an unknown device.
• Support for listed Windows releases: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the individual package’s compatibility requirements. Match the driver to your operating system and 32-bit or 64-bit architecture.

How to Install ZTE CMCC DIAG Interface (COM62) Driver

1. Check the device details. Open Device Manager and locate the ZTE interface under Ports (COM & LPT), Other devices, or USB devices. Review its hardware IDs under Properties > Details to help confirm the correct package.
2. Choose a compatible package. Before starting the ZTE CMCC DIAG Interface (COM62) driver download for Windows, verify the supported operating system, architecture, and hardware IDs. If a free download is offered, check its source and publisher rather than relying on the label alone.
3. Extract and install. Unpack the downloaded archive if necessary. Run the supplied installer, or select Update driver in Device Manager and browse to the extracted driver folder.
4. Reconnect and verify. Restart Windows if prompted, then reconnect the device. Confirm that the interface appears without a warning icon and note its assigned COM port.
5. Configure your diagnostic tool. Select the detected port in compatible software. For Windows 10/11 systems, check support carefully: Windows 10 is listed, but Windows 11 compatibility is not confirmed.

Keep the driver updated when ZTE provides a compatible release that addresses your issue or system requirements. The latest version is useful only when it supports your specific device and Windows edition; avoid replacing a working driver with an unverified update.
