VCDS, a powerful diagnostic tool for VAG vehicles (Volkswagen, Audi, Group), requires up-to-date USB drivers for seamless communication with your car. If you’re experiencing connectivity issues or need to install drivers for a new VCDS interface, this guide provides a comprehensive walkthrough for updating your VCDS USB drivers in Windows. While VCDS often installs drivers automatically, manual installation may be necessary. This guide focuses on troubleshooting scenarios where automatic installation fails.
When to Update VCDS USB Drivers
You might need to update your VCDS USB drivers if:
- New VCDS Interface: You’ve purchased a new VCDS interface and need to install its drivers.
- Connectivity Problems: Your existing VCDS interface isn’t connecting to your computer or vehicle.
- Windows Update: A recent Windows update might have affected your existing drivers.
- Driver Corruption: Your current VCDS USB drivers might be corrupted or outdated.
Installing VCDS USB Drivers Manually
Before proceeding, ensure you have downloaded and installed the latest version of VCDS software from the official Ross-Tech website.
Step 1: Connect Your Interface
Plug your Ross-Tech USB interface into a USB port on your computer. It’s not necessary to connect to the vehicle at this point.
Step 2: Check for Automatic Installation
Windows often attempts to automatically install drivers for new hardware. Check your taskbar for a notification about new hardware found. If the “Found New Hardware Wizard” appears, let the process complete.
Step 3: Manual Driver Installation (If Automatic Installation Fails)
If the automatic installation fails or doesn’t initiate:
-
Open Device Manager: Right-click on “My Computer” (or “This PC” in newer Windows versions) and select “Manage”. In the Computer Management window, select “Device Manager”.
-
Locate Your Interface: Your Ross-Tech USB Interface might be listed under “Universal Serial Bus controllers” or “Other devices” with a yellow exclamation mark indicating a driver issue. Alternatively, it may appear as an unknown device.
-
Update Driver: Right-click on the interface and select “Update Driver Software”.
-
Browse for Driver: Choose the option to “Browse my computer for driver software”.
-
Locate VCDS Driver Folder: Navigate to the VCDS installation directory on your computer. This is usually “C:Ross-TechVCDS”. Click “Next”.
-
Install Driver: Windows should locate and install the appropriate driver. You might see a warning about unsigned drivers. Click “Continue Anyway” to proceed.
-
Complete Installation: Follow the remaining on-screen prompts to complete the driver installation.
Step 4: Verify Driver Installation
- Launch VCDS: Open the VCDS software.
- Select USB Port: In the VCDS options, select “USB” as the communication port.
- Test Connection: Click the “Test” button. A successful connection will display information about your interface.
Troubleshooting
If you encounter problems during the installation:
- Administrator Rights: Ensure you are logged in with administrator privileges.
- Driver Signing: Adjust your driver signing settings in Windows to allow installation of unsigned drivers if prompted. (Control Panel -> System -> Hardware -> Driver Signing). You might need to set it to “Warn”. Try the installation again from step 3.
- Contact Ross-Tech Support: If problems persist, contact Ross-Tech directly for assistance.
Keeping Your Drivers Updated
For optimal performance, regularly check the Ross-Tech website for updated VCDS software and drivers. Keeping your drivers current ensures compatibility and addresses potential bug fixes.
