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

On my system - 14.04 - kernel 3.13.0-24-generic:

Bluetooth adapter is detected:

hciconfig shows hci0 Type: BR/EDR Bus: USB
with a BD Address, and MTU
Up Running

rfkill list shows:

Dear All,

Pls help me to provide the solution for BT issue.

Wifi is working but bluetooth not working.

The issue is still not fixed, using Ubuntu 14.10 with 3.16.0-24-generic kernel.

I've tried changing the DeviceID in /etc/bluetooth/main.conf with no success, the system seems to think everything is running correctly.

Here is some data I collected : http://pastebin.com/E0Q05x0D

I have the same problem in xubuntu 14.04 - 3.13.0-43-generic on Acer ES1-511 with Qualcom Atheros QCA9565 /AR9565

I have the same probem on Ubuntu Gnome x64 14.10 3.16.0-28-generic on Acer E3-111, also with Atheros QCA9565/AR9565. Please let me know if I can be of any help to diagnose and repair this issue.

Hey people, I (with a lot of help from a very helpful askubuntu user, user300665) managed to get Bluetooth working. It is relatively simple, you just have to add the USB vendor ID into the btusb and ath3k modules. I'm submitting a patch here in a few moments.

Kernel modules ath3k and btusb are missing the necessary device descriptions

I have attached a patch which fixes the issue for me. Please notify me if I did anything wrong, I am quite new at this. Also, please contact me if I can be of any help in integrating this into the official kernel.

Sadly, after a reboot this no longer works and I have no idea why.

This time I got it right. The USB vendor:product description needs to be in the blacklist section of the btusb file; it only worked by chance the first time I tried; now it works after a reboot. (We have to prevent btusb from managing this before its firmware is loaded or whatever, see ath3k on wireless.kernel.org)

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.19 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hi,
Sorry for taking this long to respond. I've tested both the kernel you suggested and the one after it (3.19-rc3-vivid), and Bluetooth worked in both. Also Bluetooth worked in my current kernel (3.16.0-28) with the original modules moved back and also the older kernel present on my system (3.16.0-23). In the meantime a couple of packages were updated, including linux-firmware, which may have something to do with it. I'll try downgrading that and see if it re-introduces the bug.

Update: I was wrong. While testing the issue I only restarted my machine which did not power cycle the Bluetooth radio, so it probably retained its firmware between reboots and it worked regardless of the kernel I used. It turns out a proper shutdown and restart re-introduces the bug on 3.16.* (unpatched), but Bluetooth is indeed working on 3.19-*. Also, the version of linux-firmware has nothing to do with it. I'll now tag this bug report accordingly; that is, add the 'confirmed' and 'kernel-fixed-upstream' tags.

This affects me on a HP6715b laptop. The Bluetooth that worked in 12.04 is not detected in 14.04
My wifi works but is shown as a Broadcom BCM4311 so I'm not sure about the "Integrated Module" below.

 usb_device.vendor_id = 1008 (0x3f0)
  usb_device.product_id = 5917 (0x171d)
  usb_device.vendor = 'Hewlett-Packard'
  info.vendor = 'Hewlett-Packard'
  usb_device.device_revision_bcd = 256 (0x100)
  usb_device.max_power = 0 (0x0)
  usb_device.product = 'Wireless (Bluetooth + WLAN) Interface [Integrated Module]'

I started a thread on the Ubuntu forum which has a few more details.

Can you see if this issue also occurs with the latest 3.13 upstream version? It can be downloaded from:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.11-ckt13-trusty/

If the bug does still exist, we can perform a reverse bisect to identify the commit that fixes this in 3.19.

I've since upgraded to the 3.16.0-29 kernel. Bluetooth still doesn't work with it, but my patch still fixes it. Upon a power cycle, ath3k did not load automatically, but with a modprobe it loaded and worked. Running depmod fixed that too. I also tried the 3.13.11-ckt13-trusty kernel you posted. The bug exists in it.

Jamie (jgwild), your Bluetooth chip has a different USB V/PID, different Bluetooth chip manufacturer, and the problem causes entirely different symptoms (detected, but non-functional / not even detected). Although I'm no authority on this, I think your problem will not be fixed by this bug report as it seems to be entirely unrelated; I think you will get better results by opening a new one.

Joseph, this should be the commit http://git.kernel.org/cgit/linux/kernel/git/bluetooth/bluetooth-next.git/commit/drivers/bluetooth/ath3k.c?id=4b552bc9edfdc947862af225a0e2521edb5d37a0

Yes, that must be it, it matches my patch. http://git.kernel.org/cgit/linux/kernel/git/bluetooth/bluetooth-next.git/commit/?id=4b552bc9edfdc947862af225a0e2521edb5d37a0 shows both files, not just ath3k.c - I was confused at first when I opened the link above.

I'm having the same issue with:

Commit 4b552bc9edfdc947862af225a0e2521edb5d37a0 is in mainline as of 3.19-rc1. Vivid will pick up this fix and it gets rebased to 3.19.

However, the patch was no cc'd to stable, so we need to submit and SRU request for Utopic and Trusty. A request should also be sent to stable for inclusion in the stable kernels.

I built a Utopic test kernel with a cherry-pick of 4b552bc. Can folks affected by this bug test this kernel and post back? It can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1352821/

If it fixes this bug, I'll submit the SRU requests and request for inclusion in upstream stable kernels.

Note that you will need to install both the linux-image and linux-image-extra .deb packages.

Followed Joseph's advice and installed both linux-image and linux-image-extra packages from ...~jsalisbury...

NOW:

But unfortunately this had no effect on Bluetooth's ability to find any devices. Situation is still the same as in my post above. Everything seems to work ok, WiFi actually works, Bluetooth doesn't see any devices. I've tried to connect mouse and phone, no luck. Same devices connect correctly to another Ubuntu laptop.

Environment:

@Jukka, the test kernel was specifically for the 0489:e078 device. However, looking at your output, you seem to have 0489:e076. Can you open a separate bug, and I'll create a patch.

@bala, does the test kernel get bluetooth working for you?

@Joseph, thanks for the advice.

I've now opened a separate bug about the same issue with 0489:e076 here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1425252

Sorry for taking this long. @jsailsbury , I've just tried the kernel you've uploaded. It fixes Bluetooth for me.

A request has been sent upstream for inclusion in all the stable kernels.

So? Is there a quick fix? Thanks!

Does your fix is already in the vivid kernel? (I can install the vivid kernel if needed)
(Now I run Utopic 3.16.0-31-generic)

Sorry for the comments flood, I just can't edit them.
I just wanted to say my device is:
Bus 003 Device 003: ID 0cf3:3004 Atheros Communications, Inc.
  bDeviceClass 224 Wireless
  bDeviceSubClass 1 Radio Frequency
  bDeviceProtocol 1 Bluetooth
  idVendor 0x0cf3 Atheros Communications, Inc.
  idProduct 0x3004

Thanks!

@elichai2, the test kernel and patch were specifically created for the 0489:e078 device. However, looking at your comment, you seem to have 0cf3:3004. Your device seems to have been added in an early kernel by commit d9f51b51d.

It would probably be best for you to open a new bug, so we can investigate further.

@thiru, I would suggest opening a new bug if you are having bluetooth issues.
