Title:
  0489:e062 [Sony VAIO SVF1531C5E] Bluetooth adapter does not see BT
  devices

Status in linux package in Ubuntu:
  Triaged

Bug description:
  The Bluetooth adapter is detected and apparently working but, when
  choosing "Configure a new device", the device list is always empty (it
  cannot see any BT device around).

  But, if I boot into Windows 8 just before booting into Ubuntu, the
  adapter works perfectly and it sees all BT devices. It seems the
  Windows 8 driver is performing some activation to the BT adapter.

  Test case:
  Step 1: power on the Sony VAIO SVF1531C5E and boot into Ubuntu 14.04.1.
  Step 2: type "dmesg | grep Bluetooth" and look at the output. Notice the timeout error shown at the end:
  [   15.691891] Bluetooth: Core ver 2.19
  [   15.691912] Bluetooth: HCI device and connection manager initialized
  [   15.691918] Bluetooth: HCI socket layer initialized
  [   15.691920] Bluetooth: L2CAP socket layer initialized
  [   15.691926] Bluetooth: SCO socket layer initialized
  [   19.571783] Bluetooth: RFCOMM TTY layer initialized
  [   19.571794] Bluetooth: RFCOMM socket layer initialized
  [   19.571799] Bluetooth: RFCOMM ver 1.11
  [   19.619432] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
  [   19.619435] Bluetooth: BNEP filters: protocol multicast
  [   19.619442] Bluetooth: BNEP socket layer initialized
  [   21.772160] Bluetooth: hci0 command 0x1003 tx timeout

  Step 3: try to list BT devices by clicking on the bluetooth icon at the top right of the screen and then selecting "Configure a new device". The device's list will be empty: it should list all bluetooth-enabled devices around.
  Step 4: reboot the laptop and boot into a Windows partition (mine is Windows 8.1).
  Step 5: wait until it is completely booted, then just reboot.
  Step 6: boot into Ubuntu again.
  Step 7: type "dmesg | grep Bluetooth" and look at the output. This time there is no "hci0 command 0x1003 tx timeout" message at the end:
  [   15.569891] Bluetooth: Core ver 2.19
  [   15.569911] Bluetooth: HCI device and connection manager initialized
  [   15.569918] Bluetooth: HCI socket layer initialized
  [   15.569921] Bluetooth: L2CAP socket layer initialized
  [   15.569930] Bluetooth: SCO socket layer initialized
  [   19.571790] Bluetooth: RFCOMM TTY layer initialized
  [   19.571801] Bluetooth: RFCOMM socket layer initialized
  [   19.571806] Bluetooth: RFCOMM ver 1.11
  [   19.719275] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
  [   19.719278] Bluetooth: BNEP filters: protocol multicast
  [   19.719285] Bluetooth: BNEP socket layer initialized

  Step 8: try to list BT devices around by clicking on the bluetooth
  icon at the top right of the screen, and then selecting "Configure a
  new device". The device's list will have all the bluetooth devices
  around, and you will be able to pair them perfectly.
