I an Android newbie and software developer. I just got this used HTC Droid Incredible and installed cyanogen on it. I read that when I plug it in to the laptop with a USB cable I should see a notification at the top of the phone's screen, and then be able to copy over music, etc. But I plug it in and nothing happens. What's wrong? What can I do? The first thing I wanted to do was load some music.
