Hi there,
  I own a E47 now and want to connect my cell with by bluetooth.
  I checked dmesg, I got:
789:[    8.895748] Bluetooth: Core ver 2.16
791:[    8.895772] Bluetooth: HCI device and connection manager initialized
792:[    8.895775] Bluetooth: HCI socket layer initialized
793:[    8.895777] Bluetooth: L2CAP socket layer initialized
794:[    8.896042] Bluetooth: SCO socket layer initialized
795:[    9.095451] Bluetooth: Generic Bluetooth USB driver ver 0.6
853:[  501.564274] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
854:[  501.564278] Bluetooth: BNEP filters: protocol multicast
855:[  501.566146] Bluetooth: RFCOMM TTY layer initialized
856:[  501.566152] Bluetooth: RFCOMM socket layer initialized
857:[  501.566154] Bluetooth: RFCOMM ver 1.11
  But there is no bluetooth or hci devices in lspci. `hcitool dev`
returned no device, either.
  What should I do?
