Sometimes in Linux (Centos 6 in my case) the reason can be that you didn't started Android Studio as the root user. please restart android studio as the root user and try it!

Needed MTP mode, but it does not come up under the USB side. In the storage setting on the menu bar item you get to set the PC connection type as ... MTP.

check processes running, i had several adb processes running and i think this was screwing things up for me. Kill them all then restart Studio. HTC Sync Manager, GenyMotion etc and possibly when you have multiple Android Studio windows open can result in multiple conflicting adb processes.
