### ⭐⭐⭐⭐⭐ Review
*by M***I on 27 August 2025*

Veramente funzionale , avevo problemi con i vecchi dispositivi USB - UART con Windows 7 e poi con il 10 , passato a Windows 11 non c'era più verso di farli funzionare , questo è andato subito al primo colpo e mi ha permesso di continuare con il lavoro di programmazione di quei dispositivi che purtroppo hanno tale ingresso,
