I have a Plus 2 that I've had in a box for a while. I tried to pull it out and fire it up, but I can't get the computer to recognize that it was even plugged in to the USB. All that happens when I plug it in is the white power led comes on. There's no difference if I hold down the button while I plug in the cable. The blue led doesn't come on so I'm thinking that the bootloader isn't starting.
From all the posts I've read where people have this problem, they can at least get 2 leds on. Is my netduino lost?
