They go to the official Autocom website to download drivers, but the official drivers are coded to reject clone hardware. The security protocol in the official driver checks for a specific "VID/PID" (Vendor ID/Product ID) combination. If the Chinese clone uses a slightly different ID (which they often did to avoid patent lawsuits), the official driver treats the device like a brick.

If your driver lacks this, you may need like “CDP_Switch.exe”.

Before we jump into downloads and installations, we must address the elephant in the workshop. Autocom is a legacy brand. Since Delphi acquired Autocom, official support for the older CDP (Cars Diagnostic Pro) hardware has vanished. If you visit the official Autocom website today, you will find dead links.
