Correct installation is crucial for VCDS to function correctly. If issues persist, proceed to the next troubleshooting step.

2.2. Checking the USB Connection

A faulty USB connection can prevent VCDS from recognizing the interface. Follow these steps to ensure a stable connection:

• Unplug and Replug: Disconnect the interface from the USB port, wait five seconds, and then reconnect it.
• Try Different Ports: Test the interface with different USB ports on your computer.
• Avoid Extension Cables: Remove any extension cables between the PC and the interface, as they can cause signal loss.
• Check Cable Condition: Inspect the USB cable for any signs of damage, such as fraying or bending.
• Direct Connection: Connect the interface directly to the computer, bypassing USB hubs or adapters.

A stable USB connection is essential for uninterrupted communication between VCDS and the vehicle.

2.3. Reinstalling Drivers

Outdated or corrupted USB drivers are a common cause of interface recognition problems. Reinstalling the drivers can resolve these issues:

1. Download Latest Drivers: Obtain the latest USB drivers from the Ross-Tech website or the device manufacturer.
2. Uninstall Existing Drivers:
   • Open Device Manager.
   • Locate the VCDS interface under “Ports (COM & LPT)” or “Unknown Devices.”
   • Right-click the device and select “Uninstall device.”
   • Check the box to “Delete the driver software for this device” if available.
