Ez-usb Fx2 Driver

Windows caches drivers based on VID/PID. If your firmware enumerates with a new PID, Windows may automatically assign a driver (sometimes the wrong one). Use devcon.exe or manually delete the stale device entries in Device Manager (View -> Show hidden devices) before re-plugging.

EZ-USB FX2 (specifically the CY7C68013A series) is a popular high-speed USB 2.0 microcontroller used in devices like logic analyzers, cameras, and scanners. Its driver architecture allows a unique "ReNumeration" process where firmware is loaded onto the chip's RAM from the host computer upon connection, changing the device's personality on the fly.
