adb can't detect Sony Xperia s although I installed driver

Question

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" to update driver as it explained. and when I call adb devices my device didn't appear in the list.

Answer 1

A couple of things to check:

Is USB debugging turned on (Settings->Developer options->USB debugging)?

Is it recognised as an ADB device? Check on Device Manager, mine is down as a Sony sa0103 ADB Interface Driver. If not, right click on it and re install drivers.
