title: Windows 7 does not "see" Arduino Uno R3 board in its Device Manager
body: <p>I'm not sure if this is a proper place to ask such question, but I'm ran of ideas. I have plugged Arduino Uno R3 board to my laptop via USB and I try to install Arduino's drivers, but to do so, I have to have it visible on my <code>Device Manager</code>. And here is a problem, because I do not see anything which can be my Arduino board. I do not have even a <code>Other Devices</code> category in it, or a node <code>Unknown Device</code>. In addition, Arduino's the ON led is not lit. I have Windows 7 Home Edition.</p>
