Simple poweroff  and bit of waiting is not sufficient. I have to power
off, disconnect the PSU and try to start the computer (to empty
capacitors). Then after restarting the bluetooth works again.

Title:
  AR3011 Bluetooth not starting after being stoped (but detected)

Status in bluez package in Ubuntu:
  New

Bug description:
  kernel : 4.2.0-27
  onboard bluetooth controller : AR3011
  The Bluetooth was working great. I deactivated the bluetooth via the indicator, and then, impossible to start it. Neither from the settings bluetooth interface, neither via hciconfig. The service was of course started without problems.
  The device was well recognized and started, could find which usb port and everything. However hciconfig could not see it:

  $ hciconfig -a hci0                                                                                                                                                                                                                        
  hci0:   Type: BR/EDR  Bus: USB
          BD Address: 00:00:00:00:00:00  ACL MTU: 0:0  SCO MTU: 0:0
          DOWN 
          RX bytes:0 acl:0 sco:0 events:0 errors:0
          TX bytes:12 acl:0 sco:0 commands:4 errors:0

  Of course I restarted the system, tried purging all bluetooth related packages, tried installing blueman. Nothing would make it start.
  Finally I found this thread of arch linux :
  https://bbs.archlinux.org/viewtopic.php?id=171357

  So basically I shut down the computer, waited a while, started the computer and the bluetooth is functional again.
  I will try reproducing the bug. I tried, but it did not happen again. Maybe it's because I was listening music, lost signal, came back to the pc and closed bluetooth.

  Any thoughts of what is this caused by?
