When I switch to enable USB debugging in developer options I recieve a message:
ADB operation failed
ADB Debug mode is disabled by Admin.
The two most likely reasons I can think of are:
1) USB ADB Usage has been set to 'Disable' (USB Manager - Zebra Technologies TechDocs ). You can use StageNow to set this to 'Enable', Getting Started - Zebra Technologies TechDocs
2) Enterprise Home Screen is installed and USB debugging is disabled in the EHS configuration. You can enable USB debugging if this is the case.
