I'm having a weird problem with Arduino UNO rev3 and Windows XP.
I always used Arduino with my MAC OSX, but during these days, i'm trying to use Arduino on Windows XP and when i plug the USB cable, Windows is not able to recognize the device.
On the contrary, it is able to recognize Arduino Mega without problems, so I think there is some problems only with Arduino UNO.
I have different Arduino UNO boards and no one is recognized by Windows XP.
If i try to update the usb driver by specifying the Arduino driver directory, it founds no new driver files.
I also tried to install these drivers: http://www.ftdichip.com/Drivers/VCP.htm
without any success.
Can you help me, please?
I really need to make Arduino UNO work on my Windows XP
