Description Dylan Borg 2014-04-14 07:41:27 UTC

I have updated my kernel from 3.14 rc6 to the latest 3.15 code from Linus' tree. My bluetooth dongle that uses the ath3k driver no longer works. I am running the i386 (32 bit Intel) version of the kernel.

Comment 1 Daniel Kozák 2014-06-09 16:40:11 UTC

Same here,
before 3.15 my bluetooth does not use ath3k driver.
But with this commit https://github.com/torvalds/linux/commit/ca58e594da2486c1d28e7ad547d82266604ec4ce it is try to use ath3k module and failed with this error:
"Can't get version to change to load ram patch err"

blacklisting ath3k may help (does not try yet)

Comment 2 Daniel Kozák 2014-06-10 06:16:37 UTC

Hmm, I was wrong it uses ath3k on 3.14 too.

Comment 3 Daniel Kozák 2014-06-10 06:24:58 UTC

Ok my fault again, I was not wrong on 3.14 it use btusb. On 3.15 it is try to use ath3k

remove pid and vid from ath3k

With this changes my bluetooth works again

Comment 5 Daniel Kozák 2014-06-18 13:12:34 UTC

So it seems that commit https://github.com/torvalds/linux/commit/ca58e594da2486c1d28e7ad547d82266604ec4ce is wrong, so could anyone revert it? Or what I could do for remove changes which comes with that commit?

Still affected on 3.15.2-1, using Arch.
Same problem solved with given patch, thank you Daniel.

Comment 7 dutchman55 2014-06-29 12:24:41 UTC

well apparently some people had dyslexia:

From the commit == Bluetooth: Add a new PID/VID 0cf3/e005 for AR3012. ==

At the top of the original commit the VID clearly states 'e005'.
So it starts with an 'e'. then why did this 'e' change into a '3' ??

Also the persons that signed off these commit also did not see the change from a 'e' to a '3'.

PLease revert as soon as possible because this is holding me off from a kernel update.

Commit after good sleuthing from dutchman55.

Comment 9 Johan Hedberg 2014-06-30 07:53:17 UTC

It seems to me like this is already fixed in both bluetooth.git and bluetooth-next.git. The patch is called "Revert "Bluetooth: Add a new PID/VID 0cf3/e005 for AR3012." and it's also tagged to be backported to the 3.15.x stable tree.

Comment 10 mark 2014-07-01 10:25:51 UTC

@Johan, how long these things 'normally' take? I saw the revert on git.
Running 3.15.3 right now, had to patch it myself, not a big deal, though.

Comment 11 Careca70 2014-07-09 17:18:49 UTC

Updated to 3.15.3 from 3.14.9 and noticed this problem either.
In which revision the patch will be included?

Comment 12 nortexoid 2014-07-16 13:19:08 UTC

Upgraded from 3.13.0 to 3.15.5 and even 3.16rc5 and lost bluetooth. My adapter is listed by lsusb as follows:

Bus 003 Device 002: ID 0cf3:3005 Atheros Communications, Inc. AR3011 Bluetooth

Comment 13 Johan Hedberg 2014-07-16 13:34:38 UTC

The patch in question has been in the net tree already for many weeks without the net maintainer making a new pull request for Linus (which would get it to the next 3.16-rc release as well as to the 3.15.x stable releases a bit later).

Comment 14 Dylan Borg 2014-07-17 13:44:29 UTC

The patch has just hit Linus's mainline tree.
