bluetooth does not recognize new devices on ux31 on ubuntu 12.04

maybe this path must be include on kernel to solve this bug.

http://thread.gmane.org/gmane.linux.bluez.kernel/18801

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

the kernel proposed by http://wurkwith.us/kernel/ solve bluetooth problem.

Reassiging to 'linux' since this is obviously a kernel issue, not a bug in bluez.

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the following commands in a terminal window:

    sudo apt-get update
    sudo apt-get upgrade

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

I test with kernel 3.2.0-12 published at http://wurkwith.us/kernel/ , and bluetooth works fine.

I test with Ubunt oficial kernel 3.2.0-12 from updated-manager, and bluetooth fails.

I confirm that shakabra changes on kernel 3.2.2 solve this bug.
 More info: http://ubuntuforums.org/showthread.php?t=1865577&page=70

You can download this kernel precompiled fromo shakabra at this URL http://wurkwith.us/kernel/

I hope that ubuntu kernel team, can use same patch and add to official Ubuntu kernel.

I test this patch that refers my first post and it works,
http://thread.gmane.org/gmane.linux.bluez.kernel/18801

so only have to apply it
wget http://fenski.pl/zenbook/bluetooth.patch

Im still having this issue with Kubuntu 11.10 on UX31 running Kernel 3.3.0-030300rc4-generic from Ubuntu mainline.

Has the patch available at: http://wurkwith.us/kernel/ and mentioned in comment #19 been sent upstream for review?

People affected by this bug are probably wondering why the kernel team doesn't just apply the patch and fix it. The reason is that the kernel team is reluctant (not opposed) to apply any patch to a stable kernel that is not from upstream. Applying patches that don't come from upstream add greatly to the support of the kernel as other upstream patches may touch the same area as the non-upstream patch and may prevent them from applying cleanly.

To submit your patch, send your patch with the detailed description/changelog and your Signoff (ending with Signed-off-by: your name <email>), to the emails listed from ./scripts/get_maintainer.pl drivers/hid/hid-input.c (the get_maintainer.pl is from the kernel sources). Once you have sent the patch upstream and it's accepted, please drop a note here so that we can cherry-pick/include the patch into Ubuntu kernel.

Thanks in advance.

Hi Joseph,

Im not sure, but, acordding to this tutorial, https://wiki.ubuntu.com/PackagingGuide/PatchSystems, it says about: "Make sure patch is applied before anything else happens with your package"

and i found this patch by eran,
http://thread.gmane.org/gmane.linux.bluez.kernel/18801

this is sufficient, or not?

please confirm, in order to proceed to make a new patch :)

It looks like that patch was applied to upstream linux-stable in the following commit:

2d25f8b462f3b849d8913d02978657ef06e67dd8 Bluetooth: Add Atheros AR3012 one PID/VID supported

This commit has also made it into 12.04(Precise). Do you still see this bug with the latest Precise kernel? If so, that patch may not resolve this bug.

I looked closer at the commit 2d25f8b462f3b849d8913d02978657ef06e67dd8

It does not have the patch you mentioned in comment #19

Looking at the linux-stable code, I don't see that patch either. I only see the following in btusb.c:

 /* Atheros 3012 with sflash firmware */
        { USB_DEVICE(0x0cf3, 0x3004), .driver_info = BTUSB_ATH3012 },

The patch has:
/* Atheros 3012 with sflash firmware */
  { USB_DEVICE(0x0cf3, 0x3004), .driver_info = BTUSB_ATH3012 },
 { USB_DEVICE(0x13d3, 0x3375), .driver_info = BTUSB_ATH3012 },

I don't see that patch even applied to Linus' latest mainline kernel.

I was able to find that the patch was submitted upstream, but it has not been accepted as of yet:
https://lkml.org/lkml/2011/12/4/69

We should keep an eye on this upstream topic and test the latest stable kernel once the patch is accepted upstream.

It was now accepted in upstream http://thread.gmane.org/gmane.linux.bluez.kernel/19167 , but only in linux-next, not stable.

Since it's now also in Linus' tree, I submitted a request to stable at kernel.org to cherry-pick the commit to 3.2/3.3 stable. Let's see if that goes through. https://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=9498ba7a1d38d42eef4ef6d906ab1743c9f0fd6f
