Android :: ADP Will Not Recognize Phone

I found https://groups.google.com/group/android-developers/browse_thread/thre but I cannot respond to that thread anymore (perhaps they expire?). I've tried with both the 1.5 SDK and the 1.6 SDK. I have tried all the suggestions in the aforementioned thread. I can mount the device just fine, but adb does not work whether it is mounted or not. I've tried it both as root and as myself and with it in $PATH as well as using. In the dir. Adb appears to "work" as it tells me "List of devices attached". At some point right after I installed 1.5, I remember setting something up to make the USB connection easier, but I don't remember what that was. My hypothesis at this point is that is somehow interfering, but any help you can give either way would be much appreciated.
