So what do I do if my board fails the loop back test?? When i plug my board in, nothing pops up, makes a noise, or tries to install drivers. When I look at my device manager, I see a COM port, but its not called arduino anything (like the installation instructions say it will be). Uploading of the blink code doesn't work.
