Well, still not working. I've built a brand new Intel-based desktop PC. Installed Windows 7 Professional 64-bit and Android Studio 2.1.1 (along with various other software needed, like Java 8, etc.).
I have the Samsung OEM USB drivers installed and also installed the USB driver that comes with Android Studio. When I connect my device, I still don't get the prompt on the device to allow debugging. I've turned on the developer options, enabled USB debugging, revoked USB debugging auth, run adb kill-server and then adb start-server. When I run adb devices, it shows my device as unauthorized. Note that I have three Android devices: Samsung Galaxy S6 64gb, Sansung Galaxy Note 5 and Samsung Galaxy Note 10.1 2014 Edition. I get the same result from all three. Is Android Studio (or, I guess the SDK used by it) just broken? I've been trying suggestions for quite a while now and can't find the key to making this work. Note that if I connect my device via USB and copy the APK file to the phone and install it manually, it works. I just can't connect to it using adb. If there is someplace else where I can post my question to get help, please let me know - I just don't know where to go with this.
