Public bug reported:
When I suspend my laptop, it often happens that the bluetooth stops
working. From gnome settings it is shown like if I had no bluetooth
device at all.

Reloading the driver:
$ sudo modprobe -r btusb; sudo modprobe btusb;
$ sudo service bluetooth restart
None of these attempts could solve the issue.
What happens?
Bluetooth is working, I suspend my laptop, I resume my laptop -> Bluetooth
controller is no longer recognised and bluetooth service cannot be used anymore.
What would you expect?
Bluetooth controller to be recognised and working also after resume.
