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.
