The PSA XS Evolution 9780.Z5 (often referred to as the Lexia 3 or Diagbox interface) serves as the hardware bridge between your car’s OBDII port and your computer. The driver allows the operating system—typically Windows—to recognize the device as a "USB Com Board Driver" or "ACTIA USB Device."

Without the correct driver, the Diagbox software will return "Communication Error" or fail to detect the VCI (Vehicle Communication Interface) entirely. Official vs. Clone Drivers

It is important to identify if you have a genuine ACTIA unit or a "clone" (a common third-party version).

Genuine Units: Use drivers typically provided by ACTIA IME Support, where you can find "XS FAMILY" or "Lite XS" drivers compatible with Windows 10 and Windows 11. psa xs evolution 9780z5 driver upd

Clone Units: These often require specific, older driver versions (often for Windows XP or 7 32-bit) included on the CD that came with the device. How to Update or Install the Driver

If your PC does not automatically detect the interface, follow these steps to manually update:

Connect the Interface: Plug the XS Evolution into your USB port before opening any software.

Access Device Manager: Right-click the Start button and select Device Manager.

Locate the Device: Look for an "Unknown Device" or "ACTIA" entry under Universal Serial Bus controllers. Update Driver: Right-click the entry and select Update driver. Choose Browse my computer for drivers.

Navigate to your Diagbox installation folder (usually C:\AWRoot\bin\fi\) or the folder containing your downloaded drivers.

Confirm Installation: The device should now be listed as "USB Com Board Driver (Multi-instance)" or similar. Firmware Updates and Diagbox Compatibility

Updating the driver is only half the battle; the firmware inside the 9780.Z5 must match the version of Diagbox you are running. Psa Xs Evolution 9780z5 Driver Upd

To update the drivers and firmware for the PSA XS Evolution (9780.Z5)

interface, you must distinguish between the Windows USB drivers and the device's internal firmware. For most clone devices, automated updates through official software can lead to "blacklisting," so manual management is recommended. 1. Driver Installation (Windows)

The drivers for the VCI (Vehicle Communication Interface) are typically installed automatically during the initial setup of Diagbox (or standalone Lexia 3/PP2000). If you are a mechanic or a car

Automatic Setup: Plug the VCI into your USB port after installing Diagbox version 7 or higher. Windows should detect it and install the ACTIA USB drivers automatically.

Driver Variants: If the device is not recognized in Device Manager, look for drivers labeled "Multi-instance" rather than "UMDF," as the former is often more compatible with clone interfaces on older systems like Windows XP or 7.

Latest OS Support: Newer Diagbox versions (v9.85+) often include separate PSA VCI drivers that allow compatibility with Windows 10 and 11. 2. Firmware Management (PSA Interface Checker)

The internal firmware version of your 9780.Z5 determines which software versions it can communicate with.

Tool Required: Use the PSA Interface Checker (sometimes called "Scary's Interface Tool") to view and change your firmware version. Recommended Versions:

V4.2.4: Typically the stable limit for older Diagbox versions like 5.29 or 7.02.

V4.3.x+: Often required for newer Diagbox versions (v7.58 and above).

Flashing Caution: Never unplug the device during a firmware update, as this can "brick" the unit, requiring a hardware re-flash. 3. Hardware Revision ("Full Chip" vs. Clone)

If your interface is not recognized even after driver updates, it may be due to the hardware's serial number.

Blacklisting: If your serial number ends in /B, it may be blacklisted by Diagbox versions higher than 5.29.

Evolution Upgrade: To bypass this, some users perform a "hardware re-flash" or modify the bootloader on the microprocessor (MB90F546GS) to make the probe recognized as an "evolving" driver.
