    Atmel AT89C51SND1 design guide and schematic

    Atmel 89C51SND1 I'm trying to get ISP to work through USB in Windows XP but nothing seems to work. It gets picked up by Windows but only as a unknown device. I did try installing the drivers supplied with FLIP but with no success. Is it possible that the USB boot loader is not pre loaded?

    How to polarize unused input pins?
