bluetooth doesn't go up on latitude e6500 [SOLVED]

Since a few months my bluetooth is broken. I can't get it up anymore (my bluetooth-device ;-))

Here are the commands I execute:

$ hciconfig -a

$ rfkill list
1: dell-bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: yes
$ rfkill unblock bluetooth
$ rfkill list
1: dell-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: yes
$ hciconfig -a
hci0:    Type: USB
    BD Address: 00:22:68:E1:65:C1 ACL MTU: 1021:8 SCO MTU: 64:8
    DOWN 
...
$ hciconfig hci0 up

After these commands have been executed, the cycle begins again, without the device has gone up.

The messages I get in /var/log/messages.log are as follows:

After the rfkill unblock:

Does anyone have clue what the problem is and how it can be resolved?

Re: bluetooth doesn't go up on latitude e6500 [SOLVED]

Also suffering from similar problems with USB Bluetooth dongle. Have to constantly unplug & plug dongle, restart bluetoothd and sometimes reboot to get it working again. - Possible kernel driver issues?

Bus 003 Device 023: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

Seems to be error messages with hci0 going down:

Mar 23 12:54:01 echo bluetoothd[14078]: Starting security manager 0
Mar 23 12:54:06 echo bluetoothd[14078]: Adapter /org/bluez/14072/hci0 has been enabled

Mar 23 12:54:50 echo kernel: usb 3-1: USB disconnect, address 20
Mar 23 12:54:50 echo bluetoothd[14078]: HCI dev 0 unregistered

btusb_bulk_complete: hci0 urb ffff88013d191540 failed to resubmit (19)

and streams and streams of the following in dmesg until the dongle is removed

hci_cmd_task: hci0 command tx timeout

Anyone any clues as where to start resolving this?

Re: bluetooth doesn't go up on latitude e6500 [SOLVED]

My problem disappeared yesterday with the update to bluez-4.61-2, (possibly in combination with a kernelupdate?) Maybe you could try updating as well?
