Comment # 3 on bug 1201815 from Bruno Pesavento

bluez-auto-enable-devices just installs /etc/bluetooth/main.conf with an
AutoEnable=true entry that you can change. The relevant section is:
...
# AutoEnable defines option to enable all controllers when they are found.
# This includes adapters present on start as well as adapters that are plugged
# in later on. Defaults to 'false'.
#AutoEnable=false
AutoEnable=true
...
Lack of that file is apparently the cause of "inconsistent status display" on a
laptop of mine with an Atheros adapter known to be unfriendly, but your mileage
might vary since what we witness looks HW dependent.
Anyway, worth a try in my view.

Please be aware that the default configuration changes in newer versions of
bluez, like version 5.66 that is currently on Tumbleweed.
