That night the line ran without a hiccup. Arman left a sticky note on the rack: “Xinje driver v1.2 — installed. See log in maintenance.” In the morning, his colleague Sara followed his notes and brought a backup laptop online in five minutes flat. The installation had been mundanely technical but quietly heroic: one driver, one COM port, and an uninterrupted production run.
If you want, I can adapt this into a shorter troubleshooting guide, a checklist for installing Xinje USB drivers, or a version with step-by-step commands for Windows. Which would you prefer?
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. xinje plc usb driver install
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.

Installing the Xinje PLC USB driver is a vital step for establishing communication between your PC and Xinje hardware, such as the XD, XL, or XC series. Without this driver, your programming software (like XDPPro or XS Studio) will not recognize the PLC through a USB or USB-to-Serial programming cable. Step 1: Download the Correct Driver
You can typically find the necessary drivers in the Download Center of the official Wuxi Xinje Electric Co. website.
Xinje TH USB Device: This is the most common driver for direct USB connections.
USB-to-Serial Drivers: If you are using a conversion cable (like the USB-XC), you may need standard serial drivers (such as CH340 or Prolific), which are often included with the cable or the PLC software installation. Step 2: Manual Installation via Device Manager

Installing a Xinje PLC USB driver is the "handshake" that lets your PC talk to your industrial hardware. Whether you're using a direct USB cable or a USB-XC programming cable , follow this guide to bridge the gap. 1. Identify Your Cable and Controller Xinje PLCs usually connect in one of two ways: Direct USB Port: Newer models (like the ) often have a built-in USB port. USB-to-Serial Cable: Many older or slim models (XC series) require a specialized USB-XC programming cable . This cable typically uses a or similar chip to convert USB to RS232. 2. Download the Driver Do not rely on Windows to find the driver automatically. Visit the official Xinje Download Center Look for the "USB driver" "USB-to-Serial" driver under the software or tools section.
If you are using a 3rd party programming cable, you may need the CH341 driver specifically. 3. Installation Steps Disconnect the PLC:
Unplug the USB cable from your PC before starting the installation to avoid "unidentified device" errors. Run the Installer: Right-click the driver installer ( ) and select "Run as Administrator." The "Success" Check: That night the line ran without a hiccup
Once the installation finishes, plug the cable back into your PC and the PLC. Device Manager Verification: Device Manager on your Windows PC. Expand the Ports (COM & LPT) You should see "USB-SERIAL CH341 (COMx)" "Xinje USB" without any yellow warning triangles. Note the COM Port Number (e.g., COM3). 4. Configure Your Software
After the driver is "live," you must point your programming software to the right gate: (for XC series) or XINJE Config Communication Settings Serial Port Settings Select the that matched the number you saw in Device Manager. "Test Communication" to confirm the link is active. Troubleshooting Tips Driver Signature Error:
If you are on Windows 10 or 11 and the driver won't install, you might need to temporarily disable driver signature enforcement in your Windows startup settings. Cable Sequence:
Always connect the cable to the PC first, wait for the chime, and then connect to the PLC. for your particular Xinje PLC model? Download Center - Wuxi Xinje Electric Co., Ltd.

Test: Plug the cable into a different device (e.g., a USB printer). If the printer works, the cable is fine. If not, replace the cable.
Once the installation is complete:
When Arman’s factory upgraded its assembly line, the new Xinje PLC arrived in a nondescript cardboard box: brushed metal case, terminal blocks labeled neatly, and a small USB port tucked into one side. The technician’s guide promised “plug-and-play convenience,” but Arman had learned to trust manuals only after a skeptical sigh and a cup of coffee.
Do NOT plug the PLC in yet. First, prepare Device Manager.
Many “failed installations” are actually cable failures. XINJE PLCs are sensitive to cable quality.
Once your driver is working, protect it:
