Just a few things that were hanging me up:
1: You need the Android SDK from
Android SDK | Android Developers. I put it in my DroidXRoot folder which is in my C:. (So it's C

roidXRoot/android-sdk-windows/).
2: If, when you run "adb devices" you get "adb is not recognized as and internal or external command, operable program or batch file.", then you need to do a little extra.
-in Windows 7/Vista. click start and type system var and hit enter. Go into "Environment Variables". From here, select "path" from the bottom list box and choose "edit". Add your sdk location (mine is C

roidXRoot/android-sdk-windows/tools) to the end of this. Just copy and paste the following to the end of the string which pops up when you click "edit":
;C:\DROIDXRoot\android-sdk-windows\tools
In XP, right-click "my computer" choose "properties" . from he select advanced, and then "environmental variables". Now follow the instructions just above.
Now, re-run "adb devices" and your X should show up.
