Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.13 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  Bluetooth disabled until reloading btusb module

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  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
  [sudo] password for mike: 

  [0]
  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.
