Does it have the hardware, or you need to enable in Ubuntu? –  Mitch May 29 '13 at 11:34

Your kernel would have picked it up and loaded a module for it when you started Ubuntu. From the command line, gnome-terminal type this command:

dmesg | grep Blue

If you get output simliar to the below then your laptop has bluetooth capability.

[    2.933062] usb 1-1.4: Product: Broadcom Bluetooth Device

This answer is incomplete, only the first line of the output: [ 2.933062] usb 1-1.4: Product: Broadcom Bluetooth Device signifies an actual device, rest is just bluetooth module components, it is shown even in my desktop with no bluetooth. Please make that clear in the answer. –  saji89 May 30 '13 at 5:25
    
@saji89 fair enough, done. –  kingmilo May 30 '13 at 6:09

on my Asus laptop i have a Bluetooth icon on the top right and

dmesg | grep Blue

Gets:

[    3.757769] Bluetooth: Core ver 2.16
[    3.757798] Bluetooth: HCI device and connection manager initialized
[    3.757802] Bluetooth: HCI socket layer initialized
[    3.757805] Bluetooth: L2CAP socket layer initialized
[    3.757814] Bluetooth: SCO socket layer initialized
[    3.767297] Bluetooth: Generic Bluetooth USB driver ver 0.6
[    4.332846] Bluetooth: RFCOMM TTY layer initialized
[    4.332853] Bluetooth: RFCOMM socket layer initialized
[    4.332856] Bluetooth: RFCOMM ver 1.11
[    4.340772] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[    4.340776] Bluetooth: BNEP filters: protocol multicast

but: sudo lsusb |grep Bluetooth Doesn't return anything.

also check if you have a Hardware network (airplane mode) switch. This can disable bluetooth and make it not visible to Ubuntu

The above dmesg output is not indicative of bluetooth devices. It even shows up in my desktop with no bluettoth facility. So the above output bears no use in this particular case. But if it gives something liek [ 2.933062] usb 1-1.4: Product: Broadcom Bluetooth Device at the top as @kingmilo pointed out then it shows that you have device. –  saji89 May 30 '13 at 6:36
    
But I'm puzzled regarding the output in your system. Was your bluetooth device disabled(by hardware switch) when you executed: dmesg | grep Blue and sudo lsusb |grep Bluetooth ? –  saji89 May 30 '13 at 6:38
    
BT was enabled and working when the above output was giving. no HW switch on my laptop (Asus G73) –  TiloBunt Aug 2 at 22:20

Using lsusb:

sudo lsusb |grep Bluetooth

Should give an output similar to:

Device 005: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

If there is no bluetooth device, you'll get no output for this command.
