Just got a new Uno and loaded the software and driver. When I plug the USB connector into the computer the green led comes on and the orange led blinks at a 1 sec interval before anything is loaded. When I try to upload - nothing happens - the orange led just keeps blinking - if I press the reset - it goes off blinks twice fast and starts the 1 sec routine again. Any idea what it wron?
It was a bad usb connection - works fine now
