Connecting a VCDS interface to a Windows 10 computer can sometimes result in a “Vcds Driver Not Found” error. This issue often arises after upgrading from an older operating system like Windows 7, where the interface previously functioned without problems. This article will explore common causes and solutions for this frustrating problem.
Understanding the “VCDS Driver Not Found” Error
The “Ross-Tech USB interface not found” message, coupled with a “USB library version…” error within the VCDS software, indicates a driver problem. This means Windows is unable to properly communicate with the VCDS hardware. Often, Device Manager will display a “Ross-Tech Direct USB Interface” under “Universal Serial Bus controllers” with an error code (Code 39 or Code 28). These codes signify a corrupted or missing driver, preventing Windows from recognizing the interface.
Common Causes and Solutions
The most frequent cause is driver incompatibility between the VCDS interface and Windows 10. While the VCDS hardware may function with older operating systems, Windows 10 might require specific drivers.
1. Reinstalling VCDS Software and Drivers:
- Complete Uninstall: Thoroughly uninstall all previous VCDS software and drivers from your system. Use the official VCDS uninstaller if available.
- Driver Cleanup: After uninstalling, manually remove any remaining Ross-Tech entries in Device Manager.
- Reinstall VCDS: Download the latest version of VCDS software from the official Ross-Tech website, ensuring it’s compatible with your specific interface (HEX-USB+CAN, etc.). Install the software following the manufacturer’s instructions. This often includes a driver installation component.
2. Manually Updating Drivers:
- Device Manager: Open Device Manager and locate the Ross-Tech device (it might be under “Other devices” or with an error symbol).
- Update Driver: Right-click the device and select “Update driver.” Choose the option to “Browse my computer for drivers” and direct Windows to the VCDS installation directory (usually C:Ross-TechVCDS). If Windows claims the driver is up-to-date, try selecting “Let me pick from a list of available drivers on my computer.”
3. Using the DPInst Utility:
The VCDS software package includes a utility called “DPInst.” This tool can sometimes resolve driver installation issues. Run DPInst as administrator from within the VCDS installation folder.
4. Compatibility Mode: In some cases, running the VCDS software in compatibility mode for an older version of Windows (e.g., Windows 7) might resolve the issue. Right-click the VCDS executable, select “Properties,” navigate to the “Compatibility” tab, and enable compatibility mode.
5. Hardware Issues: While less common, ensure the VCDS cable itself isn’t faulty. Test the cable on a different computer if possible. Also, try different USB ports on your computer.
Conclusion
The “VCDS driver not found” error can be resolved by meticulously reinstalling software and drivers, manually updating drivers, utilizing the DPInst utility, or exploring compatibility settings. If problems persist, contacting Ross-Tech directly for technical support is recommended. Their expertise can provide tailored solutions for specific interface and operating system combinations.
