Connecting your VCDS interface to a Windows 10 machine can sometimes present driver challenges. This article will guide you through common issues and provide solutions to get your Vcds Interface Driver working correctly. We’ll address the frustrating “Ross-Tech USB interface not found” error and driver error codes 39 and 28.
Understanding the Problem: VCDS Interface Driver Not Found
Many users experience connectivity problems after upgrading to Windows 10. While the VCDS interface might appear to connect (indicated by a lit LED), the software often displays the message: “Ross-Tech USB interface not found. USB library version 03.02.07 Interface NOT Found!” This usually points to a driver issue. You might also encounter error code 39 (“Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.”) or error code 28 (“The drivers for this device are not installed.”) within Device Manager.
Common Causes and Solutions
The problem often stems from Windows 10’s driver handling. Here’s a breakdown of common causes and how to fix them:
Driver Compatibility:
Windows 10 might automatically install a generic driver that’s incompatible with your VCDS interface. Manually installing the correct driver from the Ross-Tech website is crucial.
Solution:
- Download the latest VCDS software: Visit the official Ross-Tech website and download the latest version of the VCDS software.
- Uninstall existing drivers: Go to Device Manager, locate the “Ross-Tech Direct USB Interface” (or similar), right-click, and select “Uninstall device.” Check the box to delete the driver software if available.
- Disconnect the interface: Unplug your VCDS interface from your computer.
- Run the VCDS installer: Install the downloaded VCDS software. This should include the necessary drivers. Follow the on-screen instructions carefully.
- Connect the interface: After installation, connect your VCDS interface. Windows should now recognize it and install the correct driver.
Driver File Corruption:
Existing driver files can sometimes become corrupted, preventing proper installation.
Solution:
- Clean Installation: After uninstalling the existing drivers (as described above), try restarting your computer before installing the latest VCDS software. This can help ensure a clean installation.
- Driver Signature Enforcement: In rare cases, driver signature enforcement might be blocking the installation. Temporarily disabling this feature can sometimes resolve the issue. (Consult Microsoft documentation on how to safely disable driver signature enforcement.)
USB Port Issues:
Occasionally, the problem might not be the driver itself, but the USB port.
Solution:
- Try Different Ports: Connect your VCDS interface to different USB ports on your computer. Avoid using USB hubs.
- Check Port Functionality: Test other USB devices in the suspected problematic port to rule out a hardware issue with the port itself.
Verifying Driver Installation
After attempting these solutions, check Device Manager. The VCDS interface should appear under “Ross-Tech Direct USB Interface” or a similar category without any error flags. Running the VCDS software’s built-in test function should confirm successful communication. If the issue persists, contact Ross-Tech directly for further support, providing details about your operating system, VCDS version, and the troubleshooting steps you’ve already taken.
