I want to use my Xperia S for debugging, so I followed the OEM USB Drivers instructions step by step but still not work, I didn\'t find "Android Composite ADB Interface
I had the same problem and no matter what i did and how much I've searched the web for a solution, nothing helped! (all this of course on windows 8)
but the thing is..
i tried this procedure on windows 7, connected the device(both Sony Xperia S and Samsung Galaxy Tab 10.1) then in the device manger i updated the driver then the andriod ADB interface appeared.
hope this helps!
