On 12.10 development version as of Fri Oct 12 21:54:30 EDT 2012

The bluetooth controller built into my Dell XPS 14z isn't working

'sudo service bluetooth restart' yields:

I'm able to turn on/off bluetooth via the indicator but the off/on button under Settings -> Bluetooth doesn't change.

'hcitool dev' doesn't list any devices

Status changed to 'Confirmed' because the bug affects multiple users.

[AndreyKl (deepmindster)]

the same problem. but for usb bluetooth adapter. and problem reveals itself after reboot only. so, stepts to reproduce are:

1) boot into ubuntu and log in as user

2) insert bluetooth adapter into usb port (bluetooth will work fine at this step)

3) reboot system

expected result: working bluetooth

real result: the same as in original description.

USB Adapter is

# lsusb
Bus 004 Device 002: ID 1131:1004 Integrated System Solution Corp. Bluetooth Device

[AndreyKl (deepmindster)]

also, looks like usb port is 1.1:

# lsusb
Bus 004 Device 002: ID 1131:1004 Integrated System Solution Corp. Bluetooth Device
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

[AndreyKl (deepmindster)]

one thing more, just have rechecked..

there is no problem if adapter is connected to usb 2.0 port. So, only usb 1.1 affected for me. tested with ubuntu 12.10 and 11.10

[Rudd-O (rudd-o)]

I have the same problem. AFAICT usb2.0 is affected. latest ubuntu.

This is reported against an old version of Ubuntu and many things has changed since then. Because of that we won't fix this issue however if this behavior repeats on a modern version please fill a bug report against it and we will take it from there.
