Here's my idea: add a "trust" setting to developer mode, which let the adb automatically enabled only if phone connect to a trust machine. 1. enable developer mode; 2. connect USB cable; 3. dialog to ask "trust this machine?" options are "always", "only once" or "no" ; 4. an unique ID will appear in the "trust" list ; 5. next time when connect to USB, adb will be activated if "always trusted"
