Unlike a standard USB flash drive, MCGS HMIs use a proprietary communication protocol over USB. Without the correct driver, your PC will detect the device as "Unknown Device" or fail to establish a download connection.
Click and select the driver folder located in Step 1.
Follow these steps to properly install the driver and connect your PC to the HMI. Method 1: Automatic Installation via MCGS Software
The MCGS USB driver is a software component that allows Windows to communicate with Kunlun Tongtai HMI hardware. When you plug a USB cable from your PC into the HMI's slave port, Windows reads the hardware ID. The driver translates programming commands from the MCGS software environment into data the screen understands. : Download the latest version of MCGS Pro
Hold the Shift key while clicking in the Windows Start Menu.
To ensure you have the latest drivers, always download the full configuration software from official or reputable industrial sources:
When the HMI boots up and the USB connection is detected, Windows will attempt to install the device.
The MCGS HMI USB driver is a software component required for a Windows-based PC to communicate with an MCGS brand touch panel (HMI) via a USB cable. Unlike standard USB storage drivers, this driver enables between the configuration software (MCGS Embedded or Universal Development Environment) and the target HMI device. Without the correct driver, the PC will either fail to recognize the HMI or will only see it as an unrecognized device. Re-install the MCGS USB driver using the Step-by-Step
USB communication failure is one of the most common issues encountered by automation engineers. If your MCGS software displays a "Communication Timeout" or "Device Not Found" error, apply these fixes: 1. Windows Driver Signature Enforcement Issues
| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | | Driver signature enforcement | Disable Secure Boot or temporarily disable driver signature enforcement (Shift + Restart → Troubleshoot → Startup Settings → Disable driver signature enforcement). | | COM port number > 10 | Windows assigns high COM port | Manually change to lower COM port (e.g., COM3) in Device Manager → Port Settings → Advanced. | | Download fails mid-way | USB cable too long or poor quality | Use shielded USB cable < 3 meters. Avoid USB hubs. | | Driver conflicts with other USB devices | Multiple CDC drivers | Uninstall other COM port drivers temporarily or reinstall MCGS driver last. | | HMI not detected at all | Wrong USB mode on HMI | Some MCGS HMIs require enabling USB Download Mode in the HMI’s system settings (check HMI manual). |
