USB Single Port (COM8) Driver

The USB Single Port (COM8) driver helps Windows recognize a Zte device’s USB serial interface and allows compatible software to communicate with it through a COM port. You may need this driver if your connected device appears as unknown hardware, shows a warning in Device Manager, or is not detected by an application that requires a serial connection.

Key Features

• Enables USB-to-serial communication between Windows and the corresponding interface on compatible Zte hardware.
• Makes the serial interface available to applications that connect through a Windows COM port.
• Supports driver setup on Windows 10, 8.1, 7, Vista, and XP when you select a package matching your device and operating system.
• Can help resolve recognition problems caused by a missing or incorrectly installed driver. The assigned port number may differ from COM8 depending on your computer’s configuration.

How to Install USB Single Port (COM8) Driver

1. Check your device and Windows version. Open Device Manager and locate the Zte device under “Ports (COM & LPT),” “Other devices,” or USB-related entries. Check its Hardware IDs under Properties > Details, and confirm whether Windows is 32-bit or 64-bit.
2. Choose a matching package. Before starting your USB Single Port (COM8) driver download for Windows, verify that the package supports your hardware ID and operating system. Look for the latest version compatible with your device, rather than assuming the newest package supports every model.
3. Download and extract the files. Use a trusted source for a free download, and extract the archive if necessary. Avoid installers that require unrelated software or ask you to disable security protections.
4. Install the driver. Run the included setup program, if provided, and follow its instructions. Alternatively, right-click the device in Device Manager, choose “Update driver” or “Update Driver Software,” and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if prompted, reconnect the device, and check for a COM-port entry without a warning icon. Select the assigned port in your application; it may not be COM8.

Keep the driver updated when a compatible release addresses connection issues or operating-system changes. For Windows 10/11 systems, check support carefully: Windows 10 is listed for this device, but Windows 11 compatibility is not confirmed here. Before an update, retain the working installer so you can restore your previous setup if needed.
