Title:
  0930:0214 [Toshiba TECRA R700 PT318C-00F001] Bluetooth disabled until
  reloading btusb module

Status in “linux” package in Ubuntu:
  Confirmed

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".

  Bluetooth works fine in Windows.

  Still, `rfkill list bluetooth` lists two devices:
  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":
  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:
  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

  sudo hciconfig hci0 up
  [sudo] password for mike:

  [0]
  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.

  WORKAROUND: 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.
