I tried installing Android Studio 2.x on my PC at work. It is also running Windows 7 (although it is Enterprise edition). On that machine, I was able to connect my phone and 'adb devices' recognized it. I was prompted (on the phone) to allow USB debugging and was even able to deploy a sample application to the phone and run it.
The problem seems to be with my specific PC. As I said before, I had uninstalled Android Studio (which includes the SDK) and reinstalled it, but this didn't help. There must be something else which needs to be cleaned up which is not - that is preventing the phone from asking if it is okay to debug via USB. Can anyone please help? I really can't re-install the OS on my PC or replace it with a new machine - there must be some way to debug this. Is there someone to whom this can be escalated when the easy answers don't apply?
