It works alongside Diagbox , Lexia 3 , and PP2000 .
– It might be a misremembered or mis-typed identifier for a known industrial driver (e.g., for a PSA oxygen/nitrogen generator, an automotive diagnostic tool, or a legacy hardware peripheral). Psa Xs Evolution 9780.z5 Driver
If you are using a clone XS Evolution tool, newer Diagbox updates can detect it and disable the driver communication.
For owners of Citroën or Peugeot vehicles, few tools are as revered—and as confounding—as the PSA XS Evolution diagnostic interface. Also known by its component part number or by the front sticker code A.1281.Z , this device is the gateway to performing dealer-level diagnostics from your own garage. However, behind its professional capabilities lies a common frustration: getting the correct driver installed so your computer can talk to the car. : Reads and clears stored or pending diagnostic

If the driver is installed but not printing: If you are using a clone XS Evolution
Many clone interfaces and older ACTIA drivers lack modern digital signatures. Windows will block them silently unless you disable enforcement.
Click and browse to the standard ACTIA directory installation path. Usually, this is found at: C:\APPLIC\LEXIA\EXE\ or C:\AWRoot\bin\fi\ Look for a file named ACTIUSB.inf or inst_actia32.inf .
| Potential cause | Solution | |----------------|----------| | DiagBox 9.xx often contains firmware updates that corrupt or disable clone 9780.Z5 units. | Uninstall DiagBox completely. Use a cleaner tool (e.g. “DiagBox Uninstaller 101”) to remove registry traces. Then install DiagBox 7.83 or 7.85 instead. | | Incorrect COM port number. The diagnostic software expects the VCI on a specific COM port (usually COM1–COM4). | Open Device Manager, note the COM port number assigned to “USB COM Board Evolution”. If it is COM5 or higher, go to its Properties → Port Settings → Advanced, and change it to COM1, COM2, COM3 or COM4 (whichever is unused). | | Driver conflict from a previous installation. | Use a driver cleaner utility (e.g. DriverStore Explorer) to remove all old PSA USB COM driver entries. Then reinstall the correct driver. | | Firmware corruption. Connecting a clone 9780.Z5 to DiagBox 9.xx may have “updated” its firmware, rendering it inoperable with older software. | This is serious. Some users have recovered their VCI by reflashing the firmware using PSA Interface Checker and a known‑good firmware file (often shared on forums like NLC‘s thread). Others find the VCI permanently dead and must buy a replacement. | | Windows driver signature enforcement blocking the driver. | On Windows 7/8/10, reboot and select “Disable Driver Signature Enforcement” from the F8 boot menu before reinstalling. |
