If this is indeed a PSA automotive tool, the "driver" alone is not enough. You cannot just plug it in and expect Windows to recognize it as a usable tool. You need the software suite.
The interface acts as a multiplexer, allowing the computer to communicate with various vehicle ECUs across different protocols. AliExpress Supported Protocols: K-Line multiplexor, CAN-BUS, and SAE J1850 (PWM and VPW). Key Functions: psa xs evolution 9780z5 driver
The 9780.Z5 drivers are notoriously picky. While Diagbox v9.xx runs well on 64-bit systems, older versions (Lexia 3 / Diagbox v7) perform best on . If you are struggling on a 64-bit machine, consider using a Virtual Machine (VMWare) pre-loaded with the software. The "Clone" Problem
