I'd try closing the command prompt and restarting it. Then doing the adb devices again, and see if that works. If it doesn't, try updating the files for adb. Go to the setup.exe and it'll open a window and updated the files for 2.2.
Alas, I've tried that repeatedly; this is my fifth attempt rooting in almost as many days.
Scratch that, no joy. Updated again to dump the google APIs in, but to no avail. Everything's up to date.
What OS are you running on?
Windows 7, 64 bit.
