The SR2 USB01 is a programming cable for Schneider Electric’s Zelio Logic smart relays (SR2 series). By 2021, Microsoft had already released several major updates to Windows 10 (versions 20H2, 21H1). Schneider Electric did not provide a standalone signed driver for the SR2 USB01 in 2021. Instead, the driver was bundled within the Zelio Soft 2 software (version 5.4 or later). Users in 2021 reported success using the driver included with Zelio Soft 2, though installation required manual steps due to the lack of a modern Windows Hardware Quality Labs (WHQL) signature for the USB-to-serial bridge chip (often a Prolific PL-2303 clone or older variant).
