I am having the same problem, Arduino Uno, Com9, and I get-
Error
We could not find any board.
Are you sure you have a board connected to your computer with a USB cable? Did you just take your Arduino Board out of the box? Did you remove the conductive foam from the board? Do you see at least an LED ON on your board?
Try checking your cable connection. You can also write us on the Forum.
So here I am, my board is out of foam, yellow light blinking,green light steady, just out of the box, tried two different USB cables and two different USB ports.
Are there any suggestions to help with next steps?
Thanks,
Benjamen
