Arduino Yun not working

Question

Sorry for my bad english, I 've been programming with an Arduino Yun for two weeks by now. It suddenly stopped working, with no noticeable reason at all.

• The rx light is the only one always ON (when I power the board)
• The other lights are always OFF
• My computer doesn't detect the board ( My USB ports don't work really well, but well enough to at least detect the board i think)
• The board doesn't succed in doing the sketch I previously uploaded (when the board worked)
• I've tryed doing the 3 resets, no changes at all
• I've asked in Arduino's forum, no answer 'till yet. What could be possibly happening? Please, I need help

There are many, many things you can do to fry an Arduino, such as shorting outputs (driven high) directly to ground without a suitable resistor. It's likely you've done one of those things.

If that's the case, you'll probably just have to go and buy another one. You may get some help from some local electronics shop or a hobbyist if you can find one close but, if it's fried, there's not much you can do.

If it's a new device and you can convince the shop where you bought it that you haven't connected anything to it but the USB, you may be able to get a replacement for free, depending on your local consumer laws.

If there's even the slightest possibility that it may be your USB rather than the Arduino itself, you need to test that - get it hooked up to a different machine (preferably one with more reliable hardware) and see if you can recover.
