Public bug reported:
When I boot my machine, the bluetooth indicator isn't present. The
bluetooth section of the system control panel shows that bluetooth is
off, and "bluetooth is disabled". But flipping the switch to "on"
doesn't actually turn on bluetooth -- the switch in the GUI gets flipped
to on, but bluetooth never actually comes up. If I navigate away and re-
open the bluetooth control panel, the switch will be back to "off".
Still, `rfkill list bluetooth` lists two devices:
mike@charron:~
$ rfkill list bluetooth
0: Toshiba Bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
And hciconfig lists a device, marked "DOWN":
mike@charron:~
$ hciconfig
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:34 acl:0 sco:0 events:3 errors:0
TX bytes:12 acl:0 sco:0 commands:4 errors:0
I can ask hciconfig to bring it up:
mike@charron:~
$ hciconfig up hci0
Warning: unknown command - "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:34 acl:0 sco:0 events:3 errors:0
TX bytes:12 acl:0 sco:0 commands:4 errors:0
mike@charron:~
$ sudo hciconfig hci0 up

mike@charron:~
$ hciconfig
hci0: Type: BR/EDR Bus: USB
BD Address: E8:39:DF:37:2B:72 ACL MTU: 1021:8 SCO MTU: 64:1
UP RUNNING
RX bytes:530 acl:0 sco:0 events:24 errors:0
TX bytes:335 acl:0 sco:0 commands:24 errors:0
But neither the bluetooth indicator nor the bluetooth control panel
reflect that bluetooth is up.
To get them to work, I run `sudo rmmod btusb && sudo modprobe btusb &&
rfkill unblock bluetooth`, which causes the bluetooth indicator to be
displayed, and the bluetooth control panel to function normally. Having
to reload the bluetooth kernel module seems like a bug.
