Getting Started with the Actia PSA XS Evolution (9780.Z5) Driver
If you’re a Peugeot or Citroën owner, you know that the Actia PSA XS Evolution (9780.Z5) is the gold standard for DIY diagnostics. However, getting the driver and software—typically DiagBox, Lexia 3, or PP2000—to play nice with modern versions of Windows can be a challenge.
Here is a guide to finding and installing the correct drivers for your interface. 1. Where to Find the Driver
Drivers for the Actia XS Evolution are typically bundled with the diagnostic software rather than distributed as standalone files.
Official Support: For professional users, drivers can sometimes be found on the ACTIA IME Support page, which lists Level X drivers for the XS Family.
Software Bundles: Most users get their drivers through DiagBox. Modern "Native" versions like DiagBox 9.85 or 9.150 include integrated VCI (Vehicle Communication Interface) drivers that support Windows 10 and 11.
Third-Party Repositories: Sites like DriverScape host archives, but use caution and ensure you match your specific hardware ID. 2. Compatibility & Windows Versions
The 9780.Z5 interface is older hardware, so your operating system matters:
Windows XP / 7 (32-bit): The most stable "native" environment for older Lexia 3 and PP2000 software.
Windows 10 / 11: Requires newer versions of DiagBox (V9.xx). Many enthusiasts prefer using a Virtual Machine (VM) pre-loaded with the software and drivers to avoid registry conflicts on their main OS. 3. Installation Steps To ensure your computer recognizes the interface:
Install the Software First: Always install DiagBox before plugging in the USB cable. The installation process usually places the necessary driver files in a temporary folder or system directory.
Connect the VCI: Plug the XS Evolution into your USB port. Windows should attempt to "Search for Drivers."
Manual Update: If it fails, open Device Manager, find the "ACTIA USB Devices" or "Unknown Device," and manually point it to the installation folder of your software (typically C:\AWRoot or similar). actia psa xs evolution 9780z5 driver
Verify with Interface Checker: Use a utility called PSA Interface Checker to confirm the firmware version. For most DiagBox versions, your firmware should be around 4.2.4 or higher to be recognized. 4. Important Troubleshooting Tips
"Device Not Recognized": Try a different USB cable (specifically the shorter one if your kit came with two) or a different USB port.
Driver Type: Some users report better success with "Multi-instance" drivers rather than "UMDF" drivers in certain environments.
Clone vs. Genuine: Many 9780.Z5 units are "clones." If your software asks to update the firmware and you have a clone, decline it, as it can "brick" or lock the interface.

How to Install Actia PSA XS Evolution (9780Z5) Drivers The Actia PSA XS Evolution, often identified by the part number 9780Z5, is the gold standard for Peugeot and Citroën diagnostics. However, getting the hardware to communicate with your PC via Lexia 3 or DiagBox can be a headache.
This guide covers everything you need to get your drivers sorted and your interface recognized. 🛠️ The Core Compatibility Issue
Most installation failures happen because of modern operating systems. Architecture: Use 32-bit (x86) Windows systems. Preferred OS: Windows 7 32-bit is the most stable. Windows 10/11: Use a Virtual Machine (VM) running XP or Win 7. Driver Type:
The "Evolution" interface requires specific "Multi-Instance" drivers. 🚀 Step-by-Step Driver Installation
Before plugging in your device, ensure you have the DiagBox software suite ready, as the drivers are usually bundled within the installation folders. 1. Identify your Interface Connect the USB cable to your PC. Device Manager Device Manager "ACTIA USB Devices" or an "Unknown Device." 2. Manual Driver Update If the device shows a yellow warning triangle: Right-click the device. Update Driver "Browse my computer for drivers." C:\APP\LEXIA\EXE\VCI (standard DiagBox path). Ensure "Include subfolders" is checked. 3. Verification with PSA Checker The driver isn't enough; the must match your software version. Download a tool called PSA Interface Checker Click "Activate." It should return a serial number and version (e.g., 4.3.0). If it says "Reference Serial: Unknown," your driver is likely not mapped to the correct COM port. ⚠️ Common Troubleshooting Tips USB 3.0 vs 2.0: These interfaces hate USB 3.0 (blue ports). Always use a USB 2.0 port Driver Signature: On Windows 10, you must Disable Driver Signature Enforcement

Always use the shorter USB cable provided. Longer extensions can cause voltage drops that lead to "Communication Error" messages. 📦 What to do if DiagBox won't see the VCI
If the drivers are installed but DiagBox says "Please connect a VCI": Check the LED:
A healthy unit flashes green once then stays solid when plugged in. Firmware Flash:
Use PSA Checker to "Flash" the unit to the version required by your DiagBox (usually 4.3.7 for DiagBox 7.xx and above). Registry Fix: Ensure the driver is listed under USB\VID_103A&PID_F000 To help you get this running, could you tell me: version of Windows are you using? genuine Actia version of DiagBox (e.g., v7.83, v9.91) are you trying to connect to? I can provide the specific firmware files registry tweaks for your exact setup.
Even advanced users face hurdles. Here is a troubleshooting matrix specific to actia psa xs evolution 9780z5 driver problems.
| Error Message | Likely Cause | Solution | |---------------|--------------|----------| | "Device descriptor request failed" | Corrupted EEPROM on the ACTIA board | Use MProg or FT_PROG to reload default USB descriptors. | | "This device cannot start. (Code 10)" | Conflicting serial driver (e.g., Arduino, Prolific) | Uninstall all COM port drivers. Use USBDeview to remove ghost devices. | | DiagBox says "No interface found" | Driver installed but software points to wrong COM port | In DiagBox configuration, manually set the COM port to match Device Manager. | | Random disconnections during SIDI/EDC17C10 programming | USB power saving enabled | Go to Power Options → USB selective suspend → Disabled. Also, in Device Manager → USB Root Hub → Properties → Power Management → Uncheck "Allow computer to turn off". | | Driver installs but shows "ACTIA PSA XS (Old)" | Wrong INF file used | Force update driver → "Let me pick from a list" → Choose the specific "9780Z5" entry, not generic ACTIA. |
After the driver is installed, you must tell the diagnostic software (Diagbox/PP2000) which COM port the device is using.
The driver is not merely a file; it is the translator between your operating system and the diagnostic tool.
The 9780Z5 driver is notoriously finicky because Microsoft’s automatic driver updates often overwrite the correct Actia-signed driver with a generic Windows USB driver. This "driver replacement" breaks the proprietary handshake sequence.
