No official white paper or "deep paper" exists for the PSA XS Evolution (Part Number 9780.Z5) driver updates. This hardware is a proprietary legacy diagnostic multiplexer engineered by ACTIA for Peugeot and Citroën (PSA).

Because official technical documentation is strictly gatekept by ACTIA and PSA corporate networks, detailed understanding of its driver ecosystem relies entirely on mechanical engineering reverse-engineering and automotive software communities.

The comprehensive technical breakdown of the PSA XS Evolution driver architecture, its firmware mechanics, and manual updating procedures is detailed below. 🛠️ Hardware & Driver Architecture Overview

The PSA XS Evolution (frequently referred to in the community as the Lexia 3 VCI or Vehicle Communication Interface) serves as the hardware bridge between a Windows PC and a vehicle's OBD-II port.

The Microcontroller: The unit runs on a Fujitsu MB90F series microcontroller.

The Problem: The standard drivers were written during the Windows XP era (16-bit and 32-bit legacy code).

The Evolution Driver: When users refer to the "Evolution Driver," they are referring to a specific USB driver that forces modern 64-bit Windows operating systems (like Windows 10 or 11) to acknowledge and communicate with the legacy Fujitsu processor. 💻 The 64-Bit OS Compatibility Conflict The PSA XS Evolution 9780Z5 is almost certainly

If you are trying to install or update this driver on a modern PC, you are likely running into the 64-bit driver signature enforcement issue.

Architecture Mismatch: The core diagnostic software that relies on this driver—Lexia 3 and Peugeot Planet 2000 (PP2000)—contains 16-bit code strings. They cannot run natively on any 64-bit operating system.

The DiagBox Solution: Modern users run DiagBox (the successor software). DiagBox acts as a wrapper that can run on 32-bit or 64-bit systems. However, it silently launches Lexia/PP2000 in the background when querying older cars.

The Driver Split: There are generally two driver profiles seen in Windows Device Manager for these units:

UMDF (User-Mode Driver Framework): Often fails or causes disconnects on clone devices.

Multi-Instance Driver: The preferred, more stable driver for aftermarket interfaces. 🔄 How to Update the Driver and Firmware PSA XS Evo driver help
