There is a significant distinction to make. The new USB driver is for Windows PC communication with the HMI.
If you are working with the MCGS Pro (Linux-based) HMI models (e.g., TPC7062Ti, TPC1271Gn), you do not need a USB driver in the traditional sense. For those units, the HMI appears as an RNDIS (Remote Network Driver Interface Specification) Ethernet device over USB. For those specific models, ensure you have the RNDIS network adapter driver enabled, not the legacy COM port emulator.
For the new driver to load correctly, temporarily disable driver signature enforcement:
Do you need to update? Absolutely.
If your industrial PC runs Windows 10 LTSC or Windows 11 IoT, the old driver is a security liability and a workflow bottleneck. The new MCGS USB driver transforms the HMI from a legacy serial device into a modern, high-speed peripheral.
Bottom Line: This is not just a driver update; it is a reliability upgrade for every maintenance engineer who has ever sworn at a "Download Failed" message at 4:55 PM on a Friday.

MCGS (Kunlun Tongtai) HMI users, the USB driver is the critical link between your PC's configuration software (MCGS embedded software) and the physical touch panel. Whether you are using the classic TPC7062 series or the newer Ti/Tx series
, having the correct driver ensures stable project downloads and data logging via the USB port. Driver Overview & Installation The MCGS USB driver is typically bundled with the MCGS Embedded Configuration Software
. When you install the software, the driver files are usually located in the installation directory (e.g., C:\MCGS\Driver\USB Supported Systems : Windows 7, 10, and 11 (32/64-bit).
: Enabling the PC to recognize the HMI as a "USB Device" for high-speed project transmission. Manual Installation : If the HMI isn't recognized automatically: Device Manager on your PC. Find the unknown "MCGS" device. Right-click and select Update Driver , then browse to the Driver\USB folder in your MCGS installation path. Common USB Port Functions Newer MCGS HMIs like the feature multiple USB interfaces with distinct roles: USB Slave (Type-B/Mini-USB) : This is the primary port for programming and debugging
. Connect this to your PC to download your compiled project files. USB Host (Type-A) : Used for connecting peripherals Data Logging : Export history data and alarms directly to a flash drive. External Input
: Connect a mouse or keyboard for easier on-site configuration. Project Backup USB restore function to update firmware or projects without a PC. Troubleshooting Tips Cable Quality
: Always use a shielded USB cable. Industrial environments are prone to noise that can interrupt a download halfway through. Driver Signature : On Windows 10/11, you may need to disable driver signature enforcement if the OS blocks the older driver version from installing. Connection Polarity : Ensure your 24V DC power supply
Do not download from random "driver update" sites. Use the official McgsPro or Mcgs7 software package.
The Protocol:
Critical Note for Windows 11: You must use the mcgsusb.inf file and manually sign it using your own self-signed certificate (using SignTool), or keep the OS permanently in Test Mode. There is no official "new" signed driver.
The old driver required disabling Windows Driver Signature Enforcement (a security risk). The new driver is WHQL certified (Windows Hardware Quality Labs). It installs silently on Windows 10 and 11 (x64) without triggering the infamous "Error 52: Driver not signed" message. This means no more rebooting into "Disable Driver Enforcement" mode.
Before diving into the driver, let’s clarify how MCGS HMIs communicate via USB.
Most MCGS panels feature a USB-B (device port) or USB-A (host port) . For project downloads, you use the USB-B port (square-shaped). Your PC recognizes the HMI as a Generic USB device when in "Download Mode."
The old driver (dating back to Windows XP/7 era) was not natively compatible with:
When you connect an MCGS HMI to a modern PC without the new driver, Windows either ignores it or flags it as "Driver is not digitally signed." The result? Your MCGS software (Embedded MCGS, or MCGSPro) reports: "Communication timeout" or "No device found."
Even with the new driver, things can go wrong. Here is the reality check:
Do not look for a "new" MCGS USB driver. Look for a "new" installation method.
The driver isn't broken. Windows security is blocking it. Adapt your process, not your driver.

The fluorescent lights of the factory floor hummed in B-flat, a sound that had been driving Silas insane for twenty years. Tonight, however, the hum was the least of his problems.
The "Blue Whale" packaging line was down. Completely. Catastrophically.
Silas stood in front of the master control panel, wiping grease from his forehead with a rag that was dirtier than his face. In front of him was an MCGS TPC7062Ti HMI (Human-Machine Interface). The screen, usually a vibrant display of conveyors and temperatures, was stuck on a cold, judgmental boot logo.
"It’s the driver, isn't it?" asked Raj, the junior engineer. He was holding a laptop that looked suspiciously like it had seen the inside of a college dorm room in 2015.
"It’s always the driver," Silas grumbled. "The USB communication driver is corrupted. I've tried the old disc. I've tried the one from the forum in 2014. Nothing. Windows 10 hates it. The HMI sees the USB stick, but the PC sees the HMI as an 'Unknown Device'. We can't upload the new recipe parameters."
If they didn't get the line running by 6:00 AM, the morning shift would have nothing to do, and the plant manager would have their heads on pikes.
"This is why we should have upgraded to the Siemens panels," Raj whispered.
Silas shot him a look that could curdle milk. "The MCGS units are workhorses. They just need... persuasion. Hand me that USB drive."
It was a generic 8GB Kingston drive, battered and bent. Silas plugged it into the HMI's programming port. Nothing. He plugged it into his laptop. The laptop chirped.
"I found a forum post five pages deep on a Chinese server," Raj said, typing furiously. "It says something about a 'MCGS HMI USB Driver New'. It’s a patched version. Apparently, it fixes the handshake timeout issue on the newer Windows builds."
"Download it," Silas said. "I don't care if it's malware at this point. If it flashes the screen, I'll take the virus."
Raj clicked the link. File not found.
"Dead link," Raj groaned. "Posted in 2019. The file host went under."
Silas slumped against the railing. The silence of the stalled line was deafening. No hiss of hydraulics, no clack of solenoids. Just the hum.
"Wait," Raj said, his eyes widening. "I'm searching the string in quotes: 'mcgs hmi usb driver new'. There’s a cached archive on a Russian robotics repository. It looks sketchy."
"Do it," Silas commanded.
The progress bar crawled across the screen. 20%. 50%. The file was small, barely 2MB. A tiny little bridge between a modern PC and a piece of industrial hardware that refused to die.
Download Complete.
Raj unzipped the folder. Inside was a single executable: MCGS_USB_Driver_v3.0_Patched.exe.
"Here goes nothing," Raj said. He plugged the USB drive into the laptop, dragged the file over, and then walked the drive over to the HMI panel.
Silas held his breath. The HMI had a specific quirk: you had to plug the USB into the download port exactly when the system was searching for a storage device, or it would lock up.
"Ready?" Silas asked. His thumb hovered over the 'Download' button on the HMI touch screen.
"Ready
To install the USB drivers for a new MCGS HMI, you typically need to install the McgsPro configuration software, which includes the necessary drivers for project downloads and data transfer. Driver Installation Guide
If your PC does not automatically recognize the HMI when connected via USB, follow these steps to manually install or verify the driver: Have you tested the new driver on your specific MCGS model
Software Installation: Install the latest version of McgsPro (the modern configuration software for MCGS HMIs). The drivers are usually located in the installation directory (e.g., C:\McgsPro\drivers or similar).
Hardware Connection: Connect the PC to the HMI's USB Slave port using a standard USB cable. Manual Installation (Windows): Open Device Manager on your PC.
Look for an "Unknown Device" or a device with a yellow warning icon. Right-click the device and select Update Driver.
Choose Browse my computer for drivers and point it to the McgsPro installation folder to locate the driver files.
Verification: Once installed, the device should appear under "Ports (COM & LPT)" or "Universal Serial Bus controllers" without any warning icons. Project Download via USB
After the driver is installed, you can download your project through McgsPro: Open your project and click the Download Project button.
Go to Online Operation and select USB Communication as the method.
Click Communications Test. If it passes ("Communications tests are normal"), click Start to download the project to the HMI. Alternative: USB Flash Drive Method
If you cannot establish a direct PC-to-HMI connection, you can use a USB flash drive (HMI USB Host port) to back up or restore projects without a direct driver connection: Copy your project files to a USB drive. Insert the drive into the HMI's USB Host port. Use the HMI's system menu to import or restore the backup.
For specific troubleshooting or version-specific drivers, refer to the MCGS Series Instruction Manual or the TPC Series User Manual Install USB Driver for HMI i Series | PDF - Scribd
Pick one (1–3) or say “decide for me.” If you want option 1 or 2, specify target OS(s), whether driver should be signed, and primary use cases (e.g., file transfer, serial-over-USB/CDC, DFU firmware update, custom vendor protocol). If you choose “decide for me,” I’ll assume Windows 10/11 unsigned driver for serial-over-USB plus a sample host app and installer.
