Ubuntu 12.04.01 - i can't turn on my bluetooth. I am on a dell vostro 1500 with wireless 355 bluetooth module (bluetooth 2.0 + EDR). When i turn the bluetooth on from the indicator and then click on bluetooth settings, it says the bluetooth is disabled. Bluetooth is enabled in BIOS settings. Is there a possible fix for this?

rfkill list output is as follows:

0: phy0: Wireless LAN

Soft blocked: no
Hard blocked: no

1: dell-wifi: Wireless LAN

Soft blocked: no
Hard blocked: no

2: dell-bluetooth: Bluetooth

Soft blocked: no
Hard blocked: no

lsusb output for this device:

Bus 003 Device 005: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth) 

uname -r

3.2.0-37-generic

I have tried:

sudo su
modprobe btusb
lsmod | grep btusb

to confirm module is loaded, then

sh -c "echo 0x0a5c 0x4500 > /sys/bus/usb/drivers/btusb/new_id"

Nothing happens at all.

hcitool dev

returns no devices.

What's the output of rfkill list? –  njsg Jan 26 '13 at 13:28
    
Check your BIOS settings to see if it is enabled there. –  Stretch Jan 26 '13 at 13:33
    
Yes. It is enabled in BIOS settings. –  user1930341 Jan 26 '13 at 16:24

What bluetooth adapter do you have? I mean the numerical information, not the vendor retail name. Include the output of lsusb. You may have a similar case as How do I enable Bluetooth on my Lenovo IdeaPad Z580? –  gertvdijk Jan 26 '13 at 19:07
