[Dell Inspiron 3137] Atheros Bluetooth [0cf3:0036] does not work on this system

[Po-Hsu Lin]

CID: 201307-13940 Dell Inspiron 3137

The Bluetooth controller, Atheros AR3011 [0cf3:0036], is not working on this system.
(According to bug 1288180 and bug 1219660, this device should work in 12.04.4)

Steps:
1. Install 12.04.4 + update (3.11.0-20), boot to desktop
2. Try to pair with any device

Expected result:
* Bluetooth applet available and working normally.

Actual result:
* The Bluetooth applet is not there, just like there is no such device on this system.
* You could see this device in lsusb, but few minutes later, it will disappear.

Cause:
ath3k's firmware loading function works badly with xHCI.

[Po-Hsu Lin (cypressyew)]

Here is an external bug report, which indicates that this issue was fixed after upgarde the BIOS
https://bugzilla.kernel.org/show_bug.cgi?id=67991

I will give it a try later.

[Po-Hsu Lin (cypressyew)]

After bios upgraded from A02 to A05, this issue still exist

Upstream bug mentioned in #2, that user was using a Dell inspiron 3437 laptop, and that laptop's BIOS changelog shows:

Enhancements - Enhance Bluetooth use experience

[Adam Lee (adam8157)]

@Po-Hsu,

Could you please provide output of command "dmesg" and "lsusb -t" on those bluetooth working dell system, like inspiron 3437, Inspiron 5437 or Latitude 3440? Thanks.

[Po-Hsu Lin (cypressyew)]

Maybe it's the root_hub with xhci driver causing this issue?

[Adam Lee (adam8157)]

@Po-Hsu,

It's weird your output shows the btusb is being used...

1, please show me the output of "#modinfo btusb" on the working system 201307-13905 - Dell Latitude 3440

2, I built a testing kernel for Bug #1317453, looks like same issue, could you please take a test? http://kernel.ubuntu.com/~adamlee/lp1317453/

Thanks.

[Po-Hsu Lin (cypressyew)]

modinfo information from 201307-13905

This system has been transferred to HWE this morning, I will give that kernel a try later.

[Adam Lee (adam8157)]

This issue's root cause is the ath3k bluetooth module(hardware or software) works badly with USB3, I'm looking into it. Also this kind of issue could be solved by BIOS.

[Adam Lee (adam8157)]

@Po-Hsu,

Do you have time to install Windows on this system? Check if the bluetooth module works after driver installed and what usb controller it connected with. Thanks.

[Adam Lee (adam8157)]

@Po-Hsu,

Please ignore #11 if you haven't started yet, but to check this kernel http://kernel.ubuntu.com/~adamlee/lp1316921/, thanks

[Po-Hsu Lin (cypressyew)]

Hello Adam,

The kernel you provided in #12 works!

Steps:
1. Install 12.04.4 + kernel from http://kernel.ubuntu.com/~adamlee/lp1316921/
2. Try to pair with a Bluetooth headset

Actual result:
* Bluetooth headset works as expected in both HSP/HFP and A2DP mode

Thanks!

[Adam Lee (adam8157)]

@Po-Hsu,

I have received some reports that kernel in #12 actually doesn't work, when you have time please test three or more times to confirm, thanks.

[Po-Hsu Lin (cypressyew)]

Sure, will test it again

[Po-Hsu Lin (cypressyew)]

Hi Adam,
It seems that the kernel in #12 is not stable, sometimes it works, but after rebooting the system, it's not working again.
(not working times > working times)

[Adam Lee (adam8157)]

lts-saucy is eol(for committing), moving to trusty which is OK for certification.

[Adam Lee (adam8157)]

Our team is working on this bug with vendor, waiting new information.
