This guide provides step-by-step instructions for installing the correct USB drivers for your Ross-Tech VCDS interface on a Windows 7 computer. Proper driver installation is crucial for VCDS to communicate with your vehicle’s onboard diagnostics system.
Download and Install VCDS Software
First, download the latest version of the VCDS software from the official Ross-Tech website. During installation, avoid installing VCDS in the Program Files directory. For optimal compatibility, install it in a custom location like C:Ross-TechVCDS.
