I have a Toshiba Laptop with Windows 7 using the USB-1 with the Prolific drivers. I have the driver Prolific 3.3.11.152 dated 3/12/2010 and have completly deleted and reloaded drivers several times. When it loads it lists as not working properly. Ocaisonally it works but then after loading my BCD396XT it gives me a blue screen of death.... It used to work fine I wish I could use my radio again....
