MattairTech CDC Serial (COM12) Driver

The MattairTech CDC Serial (COM12) driver enables Windows to communicate with compatible Mattairtech USB hardware through a virtual serial port. It is intended for users who need to connect a supported board or device to serial-terminal software, development tools, or another application that uses a COM port. The COM12 label identifies the port assigned by Windows; your device may receive a different number after installation.

Key Features

• USB-to-serial communication: Provides a CDC serial interface so compatible software can exchange data with connected Mattairtech hardware.
• COM-port access: Allows applications to select the device as a serial connection, using the port number shown in Device Manager.
• Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and system architecture.
• Connection troubleshooting: Installing the correct driver can help resolve missing-driver warnings or a device that is not recognized as a serial port.

How to Install MattairTech CDC Serial (COM12) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, check the device’s hardware IDs if you need to verify that a driver package matches your hardware.
2. Choose a compatible package. Before starting a MattairTech CDC Serial (COM12) driver download for Windows, review the package’s supported devices and operating systems. Look for the latest version compatible with your setup, and use a trusted source when selecting a free download.
3. Extract and inspect the files. If the package is compressed, extract it to an accessible folder. Read any included instructions, particularly those explaining whether to connect the USB device before or after setup.
4. Install the driver. Run the supplied installer, if available. Otherwise, open Device Manager, right-click the relevant device, select Update driver, and browse to the extracted driver folder. Follow the prompts without bypassing security warnings.
5. Verify the connection. Reconnect the hardware if necessary, then check Ports (COM & LPT) in Device Manager. Select the displayed COM port in your application and use the communication settings required by your hardware.

Keep the driver updated when a compatible release addresses a connection issue or supports changes to your system. For Windows 10/11 setups, note that Windows 10 is listed as supported here, but Windows 11 compatibility is not confirmed. Verify package documentation before an update, and avoid replacing a working driver solely because another package is newer.
