OK, disregard my last post, I was using an unsupported miner.  I switched to CGminer, but it looks like I have to have something plugged in to use it?

This is my first time mining, so I'm a litle clueless.  I read through the KB, but I can't really find any other mention of anything having to be plugged in except in the part about setting up CGMiner

When I look at my miner on my account page, it's not showing any activity.  I've been mining for a little while now, and I've got a couple shares submited, but it looks like nothing is happening
