Attempt to plug in USB. When that doesn't work, turn it over and attempt the other way. When that doesn't work, look at it and see that you were correct the first time. Now the USB cord can be plugged in.
You've described it to a T! It's kind of like when I log into eBay on my laptop. The first time it's ALWAYS "OOPS! Your Password is Incorrect!" followed by "Welcome" on the second attempt, even though it fills it in for me BOTH TIMES!
