Critical Warning: Installing the wrong driver for your series can cause Blue Screen of Death (BSOD) or prevent the programming software from seeing the PLC.
By following these steps, you should have your Xinje PLC successfully communicating with your PC, ready for programming and debugging.
Blog Title: Step-by-Step Guide: Installing the Xinje PLC USB Driver (No More “Device Not Recognized”)
Published: April 19, 2026 | Category: PLC Programming / Automation
Introduction
There’s nothing worse than sitting down at your machine, cable in hand, ready to upload a new program to your Xinje PLC—only to see the dreaded yellow exclamation mark in Device Manager. If you’re using a USB programming cable (often the XVP series or direct USB ports on newer XC/XD/XG models), Windows will not recognize the device automatically.
Don’t worry. The fix is simple once you know where to look. In this guide, I’ll walk you through installing the Xinje PLC USB driver correctly on Windows 10 and Windows 11.
What You’ll Need
Step 1: Do NOT Plug in the PLC Yet
This is the most common mistake. If you already plugged it in and Windows failed to install the driver:
Now you’re ready to start clean.
Step 2: Locate the Driver Folder (Inside Your PLC Software)
Xinje does not distribute the USB driver as a separate download on their main website. Instead, the driver is bundled with their programming software. You need to have XDPPro or AutoShop installed first.
Once installed, navigate to the driver folder. Typical paths:
If you cannot find it, search your C: drive for a file named XinjeUsbDriver.inf or xjeusb.sys.
Step 3: Manually Install the Driver (The Reliable Method)
Windows will now install the driver. After a few seconds, you should see: “Windows has successfully updated your drivers.”
Step 4: Verify the Installation
In Device Manager, expand Ports (COM & LPT) . You should now see something like:
Note the COM port number. You will need to select this exact COM port inside your Xinje programming software (under Communication Setup or PC Parameter Settings).
Troubleshooting Common Issues
| Problem | Solution | | :--- | :--- | | Driver installation fails with “hash mismatch” | Disable Memory Integrity (Core Isolation) temporarily in Windows Security. Restart, install driver, then re-enable. | | COM port disappears after reboot | Reinstall driver. Check your USB cable—some cheap cables are power-only, no data. | | Windows says “Third-party INF is not digitally signed” | On Windows 10/11, go to Settings > Update & Security > Recovery > Advanced Startup > Troubleshoot > Startup Settings > Restart > Press 7 (Disable driver signature enforcement) . Then reinstall. | | PLC software cannot open COM port | Make sure no other software (like a serial monitor) is using the same COM port. Change the COM port number in Device Manager > Port Settings > Advanced. |
Final Tip: Always Eject Before Unplugging
Once the driver is working, treat the virtual COM port like a USB drive. Use the “Safely Remove Hardware” icon in the system tray before disconnecting the PLC. This prevents buffer errors and Windows lock-ups.
Conclusion
That’s it. Installing the Xinje PLC USB driver isn’t hard—it’s just hidden inside the programming software folder. Once you’ve done it manually one time, every Xinje PLC you connect afterward will likely be recognized automatically.

How to Install Xinje PLC USB Drivers: A Step-by-Step Guide Successfully connecting your PC to a Xinje PLC is a critical first step for programming, monitoring, and debugging industrial automation systems. This process typically involves installing two key components: the programming software (like XDPPro) and the specific USB-to-Serial drivers required for your communication cable. 1. Pre-requisites and Software Downloads
Before starting the installation, ensure you have the correct software for your PLC series. For most modern Xinje PLCs (XD/XL series), the standard tool is XDPPro, while older XC series may use XC Pro.
Download Center: Access official software and manuals directly from the Xinje Download Center.
Driver Files: Modern versions of XDPPro (e.g., v3.7 or v3.8) often bundle the necessary communication drivers, but separate driver files like xnetusb.inf or Silicon Labs Virtual COM Port (VCP) drivers may be required depending on your specific cable. 2. Installing the Xinje Programming Software
The USB driver installation is often part of the broader software setup. Follow these steps to install the primary programming environment:
Run the installer (e.g., XDPPro_Ver3.8.0.exe) as an administrator. xinje plc usb driver install
Follow the setup wizard prompts to select your destination folder.
Crucial Step: After the main software installation, you must often install the XNet Setup (e.g., XNetSetup_en.exe). This package frequently contains the underlying communication drivers and virtual COM port settings needed for USB connectivity. 3. Connecting the Hardware and Driver Verification
Once the software is installed, you need to verify that Windows recognizes your programming cable.
Connect the Cable: Plug your USB programming cable into your PC and the circular DIN port on the Xinje PLC.
Check Device Manager: Right-click "This PC" (or "My Computer"), select Manage, then Device Manager.
Identify the Port: Look under Ports (COM & LPT). You should see a "USB-Serial CH340," "Silicon Labs CP210x," or "Xinje TH USB Device" listed with a assigned COM port number (e.g., COM3 or COM6).
If you see a yellow exclamation mark (⚠️), right-click it, select Update driver, and browse to the installation directory of your Xinje software (usually C:\Program Files (x86)\Xinje...). 4. Configuring Communication in XDPPro
After the driver is active, you must tell the software which port to use. Open XDPPro and go to the Option menu.
Select Software Serial Port Config (or Communication Configuration).
