Ok, I managed to get it to crash and not wanting to restart. For now hciconfig
does see it:
hci0: Type: BR/EDR Bus: USB
BD Address: 00:26:83:33:58:D5 ACL MTU: 1022:8 SCO MTU: 121:3

I will try to reboot.
Method for crashing:
Disconnected my headset
from the indicator:
stopped the bluetooth
started the bluetooth (many times and it managed to start)
re-stopped the bluetooth
indicator --> device name --> connection --> on (was off)
start bluetooth
does not start anymore.
$ sudo hciconfig hci0 up
Can't init device hci0: Connection timed out (110)
Also, I tried to :
$ sudo service bluetooth force-reload
then I got an apport crash pumping out. Afterwards, a stop start did not pose
problem. Neither doing another force-reload.
I will try to reboot and see if it still see it in hciconfig.

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?
