Connecting your VCDS HEX-USB+CAN interface to a Windows 10 machine can sometimes present driver-related challenges. Users may encounter issues where the interface is not recognized, resulting in error messages like “Ross-Tech USB interface not found” or driver error codes like Code 39 or Code 28 in Device Manager. This guide provides troubleshooting steps and solutions to help you resolve VCDS USB driver issues on Windows 10.
Common VCDS USB Driver Issues on Windows 10
After upgrading to Windows 10, or even on a fresh installation, your VCDS interface might not communicate correctly with the software. While the interface LED might illuminate when connected to the vehicle, indicating power, the computer might fail to recognize it properly. This often manifests as:
- “Ross-Tech USB Interface Not Found” Error: This message within the VCDS software signifies that the necessary drivers are not correctly installed or recognized by the system.
- Code 39 Error in Device Manager: “Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.” This indicates a problem with the driver file itself.
- Code 28 Error in Device Manager: “The drivers for this device are not installed.” This usually appears when the system hasn’t located or installed the appropriate driver.
- Interface Listed Under “Other Devices”: If the VCDS interface appears under “Other Devices” in Device Manager instead of under “Ross-Tech” or a similar specific category, it indicates a driver problem.
Troubleshooting Steps
Before proceeding with advanced solutions, try these basic troubleshooting steps:
- Reinstall VCDS Software: Completely uninstall the VCDS software and drivers, then reinstall the latest version from the official Ross-Tech website. Ensure you download the correct version for your operating system (Windows 10).
- Run DPInst as Administrator: Locate the DPInst executable file in the VCDS installation directory (usually C:Ross-TechVCDS) and run it as administrator. This can sometimes resolve driver installation issues.
- Manually Update Driver: In Device Manager, right-click on the Ross-Tech USB interface (or the unknown device if it’s listed under “Other Devices”), select “Update driver,” and choose “Browse my computer for drivers.” Direct it to the VCDS installation directory.
Advanced Solutions
If the basic steps fail, try these more advanced solutions:
- Disable Driver Signature Enforcement: Temporarily disabling driver signature enforcement might allow the installation of unsigned or outdated drivers. Caution: Disabling driver signature enforcement can pose security risks, so re-enable it after installing the VCDS drivers.
- USB Selective Suspend Setting: In Windows Power Options, disable the “USB selective suspend setting” which can sometimes interfere with USB device communication.
- Uninstall Conflicting Drivers: Check for other USB devices or software that might be conflicting with the VCDS drivers and try uninstalling them temporarily.
Preventing Future Issues
Keep your VCDS software and drivers up-to-date by regularly checking the Ross-Tech website for new releases. This ensures compatibility with Windows updates and often includes driver improvements.
Conclusion
Resolving VCDS USB driver issues on Windows 10 often requires a systematic approach. By following these troubleshooting steps and solutions, you can usually overcome these challenges and establish a stable connection between your VCDS interface and your computer. If problems persist, consult the official Ross-Tech website for further support and documentation.
