Bluetooth doesn't work (hci_cmd_task: hci0 command tx timeout)

[_oOMOo_]

SRU justification:

Impact: A series of bluetooth dongles [1] do not work properly with the new
        btusb driver which replaced usb_hci. This has been fixed upstream
        (2.6.29-rc3). The required changes are all local to the btusb driver.

Fix: The following three patches are required to fix this (two as prerequisite
     and one for the actual fix). The fix deviates from upstream by the change
     of a version number and the missing resume part which does not exist for
     Intrepid nor Jaunty.

Test: Fix has been tested by bug reporters.

---

Bluetooth doesn't work for at least the following devices:
ID 1131:1001 Integrated System Solution Corp. KY-BT100 Bluetooth Adapter
ID 1131:1004 Integrated System Solution Corp. Bluetooth Device
ID 2001:f111 D-Link Corp. [hex] DBT-122 Bluetooth adapter
ID 0a5c:200a Broadcom Corp. Bluetooth dongle

They don't work properly with the newer btusb driver, which replaced hci_usb by default in 2.6.27. This hasn't been fixed upstream as of v2.6.29-rc3.

Original message below:

Association with Bluetooth works using kernel 2.6.26, since the updates to 2.6.27 (both -1 and -2) association fails. I can scan and see bluetooth devices but not pair.

Using my phone, I start the association process, the phone asks for a passkey, and in 2.6.26 the popup window appears normally allowing me to enter the passkey. In 2.6.27 the dialog box never appears.

If I use hcitool:

:~$ sudo hcitool cc 00:1B:59:96:A6:DD
:~$ sudo hcitool auth 00:1B:59:96:A6:DD
HCI authentication request failed: Connection timed out

the dialog box appears very very briefly then vanishes.

dmesg shows a couple of problems:

[25791.315446] btusb_send_frame: hci0 urb ffff880048542840 submission failed

and the syslog shows that there was an attempt to associate:

I had the same problem with Intrepid Alpha 5, then I tried to send a photo from my Nokia N70 to the PC (no problem with that), then tried to associate again my Bluetooth headset and it worked!
I use a D-Link DBT-120.

No change with 2.6.27-4

Have clean installed Intrepid Beta, and updated now to 2.6.27-6, and the problem persists.

I can confirm this bug with the same bluetooth controller.
I'm wondering if it is a specific bug with this controller?

I confirm this as a bug Bus 004 Device 003: ID 1131:1001 Integrated System Solution Corp. KY-BT100 Bluetooth Adapter

does not work on mine system to :-/

Intrepid with Linux 2.6.27-7

If I boot with old linux 2.6.26-* it works. So its probadly kernel problem. or maybe bluez related...

[_oOMOo_ (hermann-blaxhall)]

I have been able to pair (intermittently) from phone to computer using a different phone, an LG rather than a Sony Ericsson. The LG allows me to enter the passcode much more quickly than the Sony (which normally thinks for about 25 seconds before asking me to choose a passcode). Is this a timeout issue?

Having said that, even when paired I am still unable to browse files on the LG.

[tielie (mike-tielie)]

its not a time only a timerissue in the bluz stack its seems to be an KY-BT100 driver issue or/and the ehci/uhci_hsd as far as I could understand it when reading some mailinglists.

My other bt adapter ( 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)) works nicely.

[psernetz (patrick-sernetz-com)]

Same problem on my site.

 ID 1131:1004 Integrated System Solution Corp. Bluetooth Device

It's a no name device which worked in hardy but not in intrepid.

[Bernardo Kuri (accounts-bernardokuri)]

It seems my problem is more severe...

I have 2 different bluetooth dongles (Kensington & Ambicom). They both used to work fine in Hardy, but all I'm showing is timeout errors since I upgraded to Ibex. I can't pair, I can't search devices, obex... Anything.

At first, the BT icon didn't even show, but after installing a few packages through Synaptic and rebooting, that problem went away.

Another weird thing is that the timeout errors occur within a second of attempting any kind of interaction with bluetoothd.

Let me know if you guys need any extra info, and I'll try to post it up ASAP.

Things like that.

After replacing the bluetooth subsystem with the codes from 2.6.26.7

works again on "2.6.27.4".

My adapter is a KY-BT100 one.

I have the same problem. If i request authentification from my phone, it works. But i cant pair device from computer.

[Giovanni Battista Salvietti (giovannibattista-salvietti)]

Same here, seems another kernel regression....

[kylea (kylea)]

I can pair nearly at will - but what happens to me is that the bluetooth connection will not "stick". I have been getting intermittent syncing and file file transferring to work for two days then it stops for a 3 or 4 and then it will work for 8 hours and then stop.

Here is a log from the last week

1/12/2008 21:45 | kyle Amadio
      Nope that does not seem to make any difference.
      Can send files between my phone and wifes.

01/12/2008 21:37 | kyle Amadio
      Monday morning 1/12/2008 - went to work, started PC - interestingly the Dell Bluetooth switch was not on.
      Noticed this well after the PC had booted. Turned on the switch and the sync process and other Bluetooth functions worked.
     Have now returned home and 5 hours after leaving work. Bluetooth has stopped working.
     Will see if the Dell bluetooth switch being off make during the boot process makes any difference.

30/11/2008 21:03 | kyle Amadio
     Ok its Sunday 30th still not syncing - have tried a variety of things, resetting phone, re-pairing, restarting PC bluetooth.
     I can send images and music files between my 6233 and my wifes successfully, both ways.

29/11/2008 08:07 | kyle Amadio
    Shutdown - went to bed - 8 hours later - it works.
    Changed nothing on the phone

28/11/2008 22:48 | kyle Amadio
    Ok - did a shutdown and reboot. Syncing / Bluetooth stopped working.

28/11/2008 22:36 | kyle Amadio
       Well- went home and syncing is all good again.

28/11/2008 12:15 | kyle Amadio
      Syncing worked fine for two days - failed this morning (Fri 28th).

[n0PxN0p (n0pxn0p)]

Same problem, i tried 2 different bt usb-dongles (based on different chipsets), but no luck.
Everything works for me, when i start up with 2.6.24-21 stable kernel from array.org ^_^

[BrowneR (chris-scotland)]

I just built 2.6.28-rc7-git2 from kernel.org and I have the same problems with bluetooth so this is obviously not something that has been addressed upstream.

Is it worth reporting this upstream?

[BrowneR (chris-scotland)]

Bug 288613 seems related (https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/288613) and interestingly the reporter claims bluetooth worked fine in beta but not when the first intrepid RC was released. What changed kernel wise?

[kylea (kylea)]

Ok : here is what I think is going: (I have a Dell E6500 laptop)

IF I have my Bluetooth radio switch turned OFF during the Boot Up process and only turn it ON AFTER Gnome is fully loaded and all processes are finished THEN Bluetooth processes work.

Have proven this with repeated tests:

IF the Bluetooth radio switch is ON during the boot up then Bluetooth will not work.

SO what is going on - surely this is enough for you guys to make a search now. Can we change the load sequence of the Bluetooth daemon to load last ?

[Jamie Lokier (jamie-shareable)]

kylea, I usually boot with the Bluetooth radio off. It's USB internally and disconnected when I boot, then I switch it on after logging in.

I still have this pairing problem every time with 2.6.27 kernels.
So changing the load sequence wouldn't fix it.

The information we need may be to bisect between the last kernel which works reliably and the one after, trying it on someone's machine until the change which breaks it is identified. Alas I don't have the time for it, so I just run old kernels with Intrepid.

[Carlo (gentuser)]

In the same pc on Ubuntu with 2.6.27-7 bluez doesn't pair with any device, with gentoo 2.6.27-r1 bluez-3.36 it does...
I don't know is a kernel problem or what else, but with regression of bluez association works well

[Carlo (gentuser)]

Update: ubuntu kernel 2.6.27-10 doesn't solve my problem

[n0PxN0p (n0pxn0p)]

it doesn't solve my problem too )

[yngd (yanagida)]

New kernel @ Jaunty, 2.6.28 series fixes my problem.
Now I got my bluetooth headset working on Skype....finally.

Intrepid remains "unpreant" release for me, it was still fine with Hardy.

[BrowneR (chris-scotland)]

I too have just tried the Jaunty kernel.
I added this line to my apt/sources.list

deb http://gb.archive.ubuntu.com/ubuntu/ jaunty main restricted multiverse universe

and first of all just upgraded the bluez related packages to 4.21-0ubuntu1.

Now when I try to pair with my phone it immediately fails and gives an error message rather than timing out like before. I then downgraded these packages back to the intrepid version and installed the Jaunty kernel packages (2.6.28). Rebooted the new kernel. Bluetooth still wont work.

I then upgrade the bluez packages again and try to pair with my phone. Success - I am given a 4 digit password and enter this on my phone and it pairs correctly. I am however unable to do any file transfers or use my phone as an HID remote control or modem. So progress at least but still not fixed.

It seems to be a combination of factors related to bluez and the kernel as each one on its own didn't fix the problem however when they were both upgraded i was able to pair at least...

This seems like a pretty bad bug for no one to look into. Is there a workaround yet? 8.10 released ages ago, and bluetooth is a pretty standard technology. Is someone going to look into why this broke between 8.04 and 8.10? Seems like a lot of stuff broke in 64bit 8.10.

[kylea (kylea)]

I don't get - I have paid for support and still cannot get a sensible answer on this.

Just another reason why MS will keep its market share. How can we always be moving towards a new version when the basics don;t work on the majority of the hardware out there.

This behaviour is as bad - in fact worse than MS as the Linux community spends its time rightly bagging MS but then we do the same thing.

I just don't get it, can some of the zealots please explain what is going on here?

[Vadim Peretokin (vperetokin)]

No - please keep the bug report on topic. If you paid for Ubuntu commercial support, please contact them - however support implies solving user issues most likely. (at least, the contract that came with ubuntu on my laptop did).

[Launchpad Janitor (janitor)]

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

[Richard Hamnett (richard-hamnett)]

What does the comment above actually mean then? Does this mean this major bug is not going to be looked at any further? Or assigned to another team? Who should it be assigned to? This is a major flaw and causes extreme disruption particularly to users who rely on services such as calendar/event syncing.

After the hciconfig reset, this adaptor has never stopped working. Do I really have to issue hciconfig hci0 reset each boot for bluetooth to work? Is this still a kernel related problem?

[Salamandra (salamandra-redhat-bugs)]

Last day update solved the problem. Bluetooth is working now.

[Leif (leif-redhat-bugs)]

Tested with Fedora 12 Beta and is working for my bluetooth dongle now.

I recommend anyone previously getting the "hci_cmd_task: hci0 command tx timeout" give the live cd Beta a shot.

[Bug (bug-redhat-bugs)]

This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

Hi,

I can confirm it (same kernel version and BT device). It was working fine running with the latest F11 kernel (kernel-PAE-2.6.30.10-105.2.23.fc11.i686).

I inserted the the dongle and it was recognized, but the I got the tx timeout right away when I tried to use it. I was slightly more successful when I rebooted the system with the dongle connected. I attempted to pair my phone and it started the process, but got a tx timeout in the middle of the pairing transaction. After that it wouldn't communicate at all.

[Stan (stan-redhat-bugs)]

It seems this issue is fixed for me in 2.6.34 kernels. Kernels I've tried:
  - kernel-2.6.34.1-9.fc13.i686
  - kernel-2.6.34.1-15.fc13.i686

and bluetooth works as it should, it can be hot/coldplugged, hciconfig shows proper device information:

[Bug (bug-redhat-bugs)]

This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 12 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:

Can't init device hci0: Connection timed out (110)

[Marius (marius-redhat-bugs)]

Hi, All

Here is my config (I have Debian Squeeze installed on a Dell D630):

$ uname -a
Linux mrneagu-ro 2.6.32-5-amd64 #1 SMP Mon Mar 7 21:35:22 UTC 2011 x86_64 GNU/Linux
cat /etc/debian_version
6.0.1

'hciconfig hci0' gave me null BT address (00:00:00:00:00:00) and I also could not bring up the Bluetooth module:

hciconfig hci0 up
Can't init device hci0: Connection timed out (110)

lsusb gave me someting like this:
Bus 002 Device 002: ID 413c:8140 Dell Computer Corp. Wireless 360 Bluetooth

My problem occurred when I started VMWare which stole the Bluetooth adapter (usb.autoConnect.device0 = "" and even if usb.generic.autoconnect = "FALSE" it stole my Bluetooth). Then the kernel (on the host) crashed and Gnome asked me to send a report to kernel.org.

As this happened really often, I usually had to reboot to solve the problem, so I was searching for a way to reset the Bluetooth module in place and restart Bluetooth services. I found this post: http://marc.info/?l=linux-usb&m=121459435621262&w=2 to reset the any usb device.

$ sudo usbreset /dev/bus/usb/002/002

After this, every restart would not resolve the problem. Address of the module still null and "Can't init device hci0: Connection timed out (110)". The Bluetooth icon in the upper-right corner of the screen had always a red x-mark on it.

Additionally the Bluetoth module changed from bus 2 to bus 3:
Bus 003 Device 002: ID 413c:8140 Dell Computer Corp. Wireless 360 Bluetooth

Now, I resolved the problem according to this forum: http://ubuntuforums.org/showpost.php?p=8306034&postcount=4 :

I restarted in Windows and used the Bluetooth mouse there and then rebooted back in Debian and it came back by itself. So it seems that Windows somehow knows how to reset the Bluetooth module and Linux doesn't. I don't know if it's a kernel or bluez bug, but I hope this gets resolved because it is very annoying.

Thank you.
Kind Regards.

Isn't is some kind of firmware problem? I had my KY-BT100 USB Bluetooth adapter (ID 1131:1001) working perfectly fine in Fedora 14, with update to F15 it stopped to work again.

Funny thing is, if I boot F14, enable BT then reboot to F15 it works as long as the the adapter stays plugged. Replugging BT makes it unusable again.

My current software is:
kernel-2.6.38.8-32.fc15.i686.PAE
bluez-4.87-5.fc15.i686

test Fedora 14 (stock livecd)
kernel-2.6.35.6-45.fc14.686
bluez-4.71-5.fc14.i686

It turns out that some bluetooth devices that advertise themselves as "Cambridge Silicon Radio" actually use a chipset made by Accel Semiconductor. These devices do not work in Linux, and cause the symptoms described in this bug. Try opening the case on one of the dongles with a screwdriver, and looking for markings on the board. If there is a marking that contains a number beginning "AS3620QA", then this device contains a chip made by Accel Semiconductor. These devices do not work on Linux at this time. I don't know whether or not anyone is working on a driver for these, but the CSR stuff will not work, although it may appear to be partially or intermittently operational.

Mark.

It seems that we have two separate cases here.
  - adapters that never worked properly under linux
  - adapters, for which support has regressed in some particular kernel release.

[Daryll (daryll-redhat-bugs)]

Mark,

Mine is one of the Accel Semiconductor AS3620QA units, so that explains my blue tooth problems. I'm SOL for now. Luckily they were cheap. :)

Yes, for me this was a regression, as I wrote in Comment #3.

[Stan (stan-redhat-bugs)]

I found one thing that some might find interesting. My laptop (Samsung R522) has 4 USB ports. One of them is chargeable. If I plug BT adapter in this particular port it works properly, I can enable it, pair my phone, browse it content. If I plug BT adapter in any other port (including powered USB hub) device is detected, but permanently in off state.

Bluetooth is worked under F14, but stop to work with F15

[Dave (dave-redhat-bugs)]

there seem to be a number of different problems reported here, some of which may be fixed in current trees.

Given where f14 is in its lifecycle, it's unlikely to see further fixes beyond security bugs, and easily backported identified changes.

If you are still having problems on f15/f16beta, please file a new bug against the relevant release. Tracking them independently is the only way to really get a handle on this.

[fer (fer-redhat-bugs)]

Well !

My dongue was functional in fedora 14. After a migration to 15 and PUF !

"can't init device hci0", bla bla bla !

BUT !

Maybe you can see what f17 has made.
I have downloaded a SPIN with GNOME (i use KDE) and my bluetooth is live again.

Look there, into F17, and please, correct the f16 bug.
