If Windows lists your device as "USB\VID_103A", this indicates that the hardware is recognized, but the specific Actia driver is missing.
For any automotive professional or enthusiast working with Peugeot, Citroƫn, DS, or newer Opel models, the is a familiar name. As the official equipment for the manufacturer's proprietary DiagBox and Lexia-3 software, it is the key to professional-grade vehicle diagnostics.
The ACTIA PSA XS Evolution is the gold-standard hardware interface used by mechanics and DIY enthusiasts to diagnose Peugeot and Citroƫn vehicles. Operating alongside software suites like Lexia 3, PP2000, and Diagbox, this tool requires specific device drivers to communicate with your Windows PC.
Install your Diagbox software first (e.g., version 9.85 or 7.57).
Drivers for the interface are typically bundled with the diagnostic software rather than installed as standalone files.
This was the moment the "drivers" came into play. Modern wireless scanners tried to be plug-and-play, but they often missed the deep, proprietary code. The XS Evolution was different. It required the specific ACTIA driversāthe software handshake that told the carās ECU, āI am not a thief trying to steal your immobilizer code; I am the doctor.ā actia psa xs evolution drivers
Try a shorter, high-quality shielded USB cable. If the error persists across multiple computers, the interface internal chip may be corrupted or damaged. Summary Best Practices for a Stable Setup
Supported by Basic+ XS / CAT Level X driver (Version 2.9.0.8) and Lite XS Level X driver (Version 2.9.0.0).
Running Diagbox inside a pre-configured Windows 7 32-bit VMware workstation bypasses modern Windows 10/11 driver signing restrictions entirely.
Symptom 2: Error Code 52 (Windows cannot verify the digital signature)
The "Evolution" model replaced the older "XS" model, offering faster CAN switching and better stability. It interfaces with software like , PP2000 (Peugeot Planet), and Lexia (CitroĆ«n). To make this all work, you need the correct driver packageātypically based on a FTDI (Future Technology Devices International) or STMicroelectronics chipset, depending on the clone vs. original debate.

Look for a yellow triangle under "Other Devices" or "Universal Serial Bus controllers."
The Actia PSA XS is available from Actia and its authorized distributors. Pricing varies depending on the specific configuration and options chosen.
Many professional mechanics run Diagbox inside a pre-configured Windows 7 32-bit VM (using VirtualBox or VMware) on their modern Windows 11 laptops. This isolates the legacy ACTIA drivers from modern Windows updates that might break them.
Many workshops still use dedicated older laptops running Windows 7 or even XP for DiagBox 5.x and 7.x. For those systems:
Modern versions of Windows (Windows 10 and Windows 11) strictly enforce digital driver signatures. Because many aftermarket PSA XS Evolution drivers are unsigned or use legacy signatures, you must temporarily disable this feature. The ACTIA PSA XS Evolution is the gold-standard
The XS Evolution is a flexible device because it can be "flashed" to adapt to different software versions. The firmware is the internal software of the ACTIA chip.
Some users use a "PSA Interface Checker" tool to verify the firmware version. For Diagbox 7.xx and newer, a Reference "C" serial is typically required for full functionality. Troubleshooting "Device Not Found"
Ideal for legacy standalone PP2000 and Lexia 3 installations.
Ensure your driver version matches your firmware version. If you upgrade Diagbox to a newer version, use the PSA Interface Checker to flash the interface firmware so it aligns with the new drivers.
