Hi,
I'm new to Arduino and ordered my first board today.
I read the Guide page for Windows users.
The 3rd section is about Locate the USB drivers
If you are using a USB Arduino, you will need to install the drivers for the FTDI chip on the board. These can be found in the drivers/FTDI USB Drivers directory of the Arduino distribution. In the next step ("Connect the board"), you will point Window's Add New Hardware wizard to these drivers.
The latest version of the drivers can be found on the FTDI website.
Unfortunately there is no note if the USB Arduino needs the VCP or D2XX driver.
So please add this important information to the guide page.
