Testing apps on HTC EVO in Eclipse

Cannot get Eclipse to see my phone to test out apps. I downloaded the windows driver and placed it in my Android SDK folder, pointed the windows new hardware installer to it, but it still won't see my phone. Supposedly, when my phone is plugged in, Eclipse should run my application on my phone instead of the emulator. Is there anything else I need to be doing to make this happen? Any help would be greatly appreciated!
