Once the driver is installed, you should see a new COM port appear under the Ports (COM & LPT) section in Device Manager. Note the COM number (e.g., COM3 or COM4).
The 9780Z5 is a "Pass-Thru" device. It acts as a bridge between your computer (usually via USB) and the vehicle’s OBD2 port.
The Actia PSA XS Evolution (often identified by part number 9780Z5) is a professional-grade diagnostic interface widely used by Peugeot and Citroën dealerships and independent garages. It allows for deep communication with the vehicle’s ECU for diagnostics, coding, and telecoding.
Unlike modern "Plug-and-Play" devices, installing this specific tool requires careful driver management.
Before plugging in the device, it is important to understand that the XS Evolution works differently than cheaper ELM327 interfaces. It utilizes a specific USB-to-Serial protocol that requires proprietary drivers to function.
If you plug the device in and Windows attempts to install a generic driver, let it fail. You will need to install the manufacturer drivers manually.
