Hi Jason,
Did you check dmesg (diagnostic message)?log? That may give you some idea what is happening. From terminal just run dmesg (I prefer to add -T option to give the timestamp). There will be entries there anytime anything is connected or disconnected, and if there are power issues, you'll see that too. For example, here's what mine shows when running on an extremely under powered supply:
