Developer mode is a Device Manager setting that enables Android Device Bridge (ADB) commands on specific headsets when they're connected to a computer via USB. Keep in mind, you can only enable developer mode on a maximum of ten devices at one time.
To enable developer mode for individual headsets:
From your Device Manager dashboard, click ((the gray box icon with 3 dots)) for the listed device you wish to enable ADB.
Select enable ADB and confirm your selection when prompted.
To enable developer mode for a group of headsets:
From your Device Manager dashboard, find the group where you want to enable ADB, and click Group Settings
Click enable ADB and confirm your selection when prompted.
