If Windows actively prevents the installation of legacy FTDI files, you must temporarily override the operating system's security rules:
In Device Manager, right-click your and go to Properties > Port Settings > Advanced .
Check that the assigned COM port is between , as some older versions of the Galletto software cannot scan higher port numbers. 5. Safe Flashing Workflow
The is a classic and cost-effective ECU flashing tool, but getting it to cooperate with Windows 10 can be a headache due to driver compatibility issues. Many users encounter the "Device Not Recognized" error because modern operating systems often default to incorrect driver versions for the FTDI chip inside the cable.
: Modern security suites often flag the New Serial.exe or EOBD2 software as a false positive. You may need to temporarily disable real-time protection or add the software folder to your exclusions list.
: Unplug your cable, go to Device Manager , and uninstall any existing "EOBD2" or "USB Serial" devices associated with the cable to start fresh.
: The driver files that come on the generic mini-CD are deeply outdated and built exclusively for 32-bit legacy architectures.
Navigate to the extracted folder from Step 1. Select the .inf file (usually ftdibus.inf or ftdiport.inf ) and click Open, then OK.
Change the to COM 1 , COM 2 , or COM 3 (Galletto software prefers lower port numbers).
Right-click it, select , go to the Details tab, and select Hardware Ids from the dropdown. Copy the value displayed (e.g., USB\VID_0403&PID_6001 ).
Modern Windows 10 updates automatically download the latest FTDI drivers. These official drivers intentionally block or disable counterfeit hardware.
Right-click the unrecognized device (often under "Other devices" now) and select . Choose "Browse my computer for drivers" .
