 ADB access is disabled deliberately when the device is locked for
increased security (otherwise someone who's stolen your phone could
access your data via ADB); however you can disable this behaviour by
running:

 sudo touch /userdata/.adb_onlock

(Directly on the phone)

 After which adb will always be available regardless of whether your
phone is locked or not. This also gets performed automatically for you
if you flash the phone with the --developer-mode option.

Cheers,
 Mike.
