Logitech webcam not working

[Jono Bacon]

I have two cameras on my system (one internal webcam and in my screen and a USB Logitech C270). The internal camera works fine but the external USB camera does not work - it does not display in cheese or Google+ hangouts.

HI Jono,

Can you test the latest mainline kernel, to see if the bug is already fixed upstream? The latest mainline kernel is available at:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc4-quantal/

You will need to install both the linux-image and linux-image-extra .deb packages.

Thanks in advance!

[Joseph Salisbury (jsalisbury)]

One other quick question. Do you happen to know if the C270 webcam worked in earlier releases, such as Precise, Oneiric or Lucid?

[Nicholas Skaggs (nskaggs)]

I have the same issue with a Logitech C910 webcam. It *appears* like the 3.5 kernel regressed. My machine still sees the UVCcamera, but the driver fails to turn it on or make it usable. The older kernels work fine. Indeed, the webcam worked fine in precise and quantal, until the first 3.5 kernel landed.

@jsalisbury, note this thread:

http://<email address hidden>/msg47868.html

What should be do to help out here?

[Joseph Salisbury (jsalisbury)]

@Jono and @Nicholas,

I'd like to perform a kernel bisect to identify the commit that caused this regression. I would first like to confirm that you both are hitting the same bug.

@Jono, did your webcam work in Precise?

[Clay Weber (claydoh)]

Adding a "me-to" for my Logitech C510 webcam. It works in Precise (and previous versions), as well as in my previous Quantal install some weeks previously. Will test the mainline kernel shortly.

[Ari Torres (kuvanito)]

+Me
Logitech C500 does not work
Creative Live Cam VF0690 does not work

[Steve Langasek (vorlon)]

same issue on the Logitech C310.

[Joseph Salisbury (jsalisbury)]

I'd like to perform a bisect to identify the commit that caused this regression. We first need to identify the kernel version that introduced the regression. Can folks affected by this bug test the following kernels and report back the results:

v3.3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-precise/
v3.4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-quantal/

It would be great if the latest mainline kernel can also be tested to see if this is fixed upstream:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc4-quantal/

[Joseph Salisbury (jsalisbury)]

If the bug does not exist in either v3.3 or v3.4, please test the following kernel:

v3.5-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc1-quantal/

I can tell you that I was using linux-image-3.4.0-5-generic version
3.4.0-5.11 in quantal without hitting this issue. So 3.5.0-1.1 is the first
quantal kernel package with this problem.

[Joseph Salisbury (jsalisbury)]

Thanks for the feedback, Steve. Can you test v3.5-rc1[0] to see if that's when it was introduced? I can then perform a bisect to find the offending commit.

So strangely, the camera has spontaneously started working for me again. No reboot, no nothing. Earlier, I was seeing the same kind of errors as Jono:

Interesting. And you are running the latest Quantal kernel? Can you post the output of uname -a

@Jono, is your webcam still not working?

@Tessa,

Can you test v3.5-rc1[0] to see if that's when this regression was introduced? I can then perform a bisect to find the commit that caused the regression.

[Pete Graner (pgraner)]

Same thing here for me, I filed 1021261 which I duped to this bug. I have a Logitech C910 Web cam

[Nicholas Skaggs (nskaggs)]

Sorry, somehow I wasn't subbed to this bugthread :-) I can bisect away now.

@Joseph, I tried the mainline kernel you linked. My USB is completely useless so therefore the webcam doesn't work. But then again, neither does mouse, keyboard, networking, or video ;-)

[Joseph Salisbury (jsalisbury)]

@Tessa,

Were you able to test the v3.5-rc1[0] kernel?

@Nicholas,

Did you test the -rc1 kernel?

[0] http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc1-quantal/

[Nicholas Skaggs (nskaggs)]

@Joesph, yes I tested -rc1. I installed this exact kernel;

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc1-quantal/linux-image-3.5.0-030500rc1-generic_3.5.0-030500rc1.201206022335_amd64.deb

And yes, lots of drivers were missing for my hardware, but apparently USB support is completely broken for me on that kernel, so sadly I can't even use my mouse and keyboard. No matter, the webcam is also USB so therefore it wouldn't work. Since no USB devices work however, it's unclear what value we can derive from it. Send me a list of kernels, I can walk through them.

[Joseph Salisbury (jsalisbury)]

Thanks for the feedback, Nicholas.

Can you give v3.4[0] a try(To confirm the webcam works) Then give v3.5-rc2[1] a try. I'd like to find the first kernel version that causes the regression. I can then perform a kernel bisect.

[0] http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-quantal/
[1] http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc2-quantal/

I believe I have a Logitech external cam somewhere. I'll see if I can find it, so I can test here.

[Nicholas Skaggs (nskaggs)]

This bug also might be coming into play here as a seperate issue, or not..

https://bugzilla.kernel.org/show_bug.cgi?id=35922

However, like pete I'm getting "cannot set freq 32000 to ep 0x86" over and over and over on the command line.

[Joseph Salisbury (jsalisbury)]

Hi All,

I was able to reproduce this bug with a Logitec C250. It's going to be a little difficult to bisect since I ran into the same USB bug mentioned in comment #21.

The USB bug was fixed in v3.5-rc3, and I was able to reproduce the webcam bug in that kernel.

So to recap testing:

v3.4 does not have this bug.
v3.5-rc1 has a separate USB bug preventing testing of the webcam.
v3.5-rc2 has a separate USB bug preventing testing of the webcam.
v3.5-rc3 the USB bug is fixed and the webcam bug is reproduced.
v3.5 daily still has the webcam bug.

It looks like I would first have to bisect between v3.5-rc2 and v3.5-rc3 to find the commit that fixes the USB bug. I can then use that patch to fix up rc1 and rc2 to find if either of them introduced the webcam bug for this bug report.

I'll review the git logs and see if anything sticks out.

[Jono Bacon (jonobacon)]

Apologies for the delay in helping with this, Joe. Let me know if you want me to run a kernel to test.

[joseph.salisbury (joseph.salisbury-linux-kernel-bugs)]

This is a regression from v3.4 final. Many models of Logitech webcams stopped working as starting in v3.5-rc1.

I was able to reproduce this bug with a Logitec C250. It's going to be a little difficult to bisect since I ran into a USB bug that does allow any USB devices to work.

The USB bug was fixed in v3.5-rc3, and I was able to reproduce the webcam bug in that kernel.

So to recap testing:

v3.4 does not have this bug.
v3.5-rc1 has a separate USB bug preventing testing of the webcam.
v3.5-rc2 has a separate USB bug preventing testing of the webcam.
v3.5-rc3 the USB bug is fixed and the webcam bug is reproduced.
v3.5 daily still has the webcam bug.

This bug still exists in latest mainline -rc6. I'm continuing to bisect.

[Joseph Salisbury (jsalisbury)]

I've bisected down to the commit that is causing this bug:

However, the logic that caused this regression is in the following commit:
 8fdff6a319e7dac757c558bd283dc4577e68cde7 - ALSA: snd-usb: implement new endpoint streaming model

I attempted a simple revert, but it is not possible. The following commit is also involved:
d399ff9593e088d33fb38f5206c6427825892baa - ALSA: snd-usb: remove old streaming logic

This last commit just removes the obsolete unused code, which was causing a kernel compile error.

I'll continue to work on this bug and send details upstream.

Version 2 of patch to prevent crash after extended webcam use.

[Rattatoue (programcode)]

By any chance, if its not to big of a problem. Could you do the debs again with this one as well? I don't know how to apply patches and that. I just used the deb files last time.

[Joseph Salisbury (jsalisbury)]

I created a second test kernel for this bug. The test kernel can be downloaded from:
http://people.canonical.com/~jsalisbury/lp1018020/

This new kernel should fix the issue with the webcam crashing after a period of time.

Can folks affected by this bug test this kernel and report if you webcam works or not?

Thanks in advance

[Joseph Salisbury (jsalisbury)]

Just a reminder, please install both the linux-image and linux-image-extra .debs.

[Rattatoue (programcode)]

Its working as of right now, took a few times to get it to detect it again after reinstalling the .deb and restarting the computer. Had to unplug and replug back in a few times. Now its being detected and working good. Will post an update in the morning if its still working or times out again.

[Rattatoue (programcode)]

Still working here, so far no drop. All good.

[Pete Graner (pgraner)]

@Joe,

So far so good, cheese has been running for about 20 min with no issues. Tried a quick google hangout and it worked perfectly.

[Joseph Salisbury (jsalisbury)]

I created a third(Should be final) test kernel for this bug. The test kernel can be downloaded from:
http://people.canonical.com/~jsalisbury/lp1018020/

The third test kernel has the string 'v3' in the .deb file name.

Can folks affected by this bug test this kernel and report back?

Thanks in advance

[Joseph Salisbury (jsalisbury)]

Can folks that test the v3 kernel report back if they see any delay at the login screen while testing the kernel?

[Rattatoue (programcode)]

No drop in webcam for me and the login didn't really look delayed to me, but might just be because im use to a little longer in login as normal.

[Joseph Salisbury (jsalisbury)]

@Rattataoue,

Thanks for testing.

For Ubuntu users, there is a test kernel available in a Launchpad bug[0].

There is currently a fix for this being discussed on the alsa-devel mailing list. The fix should land in mainline soon.

It looks like the fix for this bug has been accepted into the latest mainline kernel. If you are affected by this bug, please test the v3.5-rc7 kernel, which can be downloaded from:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc7-quantal/

You will need to install both the linux-image and linux-image-extra .debs

[Rattatoue (programcode)]

Its hard to say if the audio with the webcam issue is fixed. As of that kernel update. My audio is messed up. Any sounds through my speakers sound far away and static. I can faintly hear people with sound maxed up. Just booted back into the previous kernel, no issues there at all. No can't set freq messages in the dmesg like before. No errors in the log at all. Its just my audio now on the machine is messed up on this kernel. I can hear myself when I test it out on audacity the audio from the webcam. So it does seem to be working, just seems like something else messed up in the process.

Volume MAXED out, sounds as if its on 1% level. Alsamixer also shows it maxed out as well.

[Rattatoue (programcode)]

Joseph, by chance can you remove my above post. I found out the issue, some how between the two kernels, pulse audio was switching my outputs. From my headphones to my speakers then back to my headphones. So 3.5 rc4 was speakers, 3.5 rc7 was headphones. My headphones are right next to my speakers. Hence the audio problem. I checked 3.5 rc7 once I realized this and sound works great and webcam so far no issue. Have yet to run it for the 14 hrs like did before about to start that. Again sorry for the bug report. Was user error not kernel.

[kernelorg (kernelorg-linux-kernel-bugs)]

Linux 3.5-rc7, containing the fix, is released. Works for me!

[Tessa Lau (tlau)]

Sorry, I thought I was subscribed to this bug's email, but apparently I wasn't. I also experienced the same USB bug with the earlier kernels which prevented me from bisecting the error. But I can confirm that the webcam works with the 3.5-rc7 kernel in #54. Thanks Joseph!

[Joseph Salisbury (jsalisbury)]

The latest Quantal kernel has be re-based to upstream v3.5-rc7. Can folks affected by this bug upgrade, and report back if this bug is fixed?

Thanks in advance

[Miguel Rodríguez (migrax)]

It works now for me.

[obitori (junk-taiotoshi)]

I was experiencing similar problems to those described above. Both Skype and PulseAudio see my VF0380 Live! Cam Optia Pro (Creative), but I get neither working microphone or working video in Skype. I have sound and I have verified my settings in Skype. I changed video to the Optia Pro. I have an HDTV card too that Skype originally mistakenly selected, but that was an easy fix. I get know microphone input response from the Skype call testing call.

I installed the below kernel:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc7-quantal/

This did not fix the problem for me. Please let me know if you would like additional information/diagnostic data.

Thanks for your effort for us users!

HI

Running a Logitech, Inc. Webcam C310 on latest Quantal mainline kernel.

I see lots of " cannot set freq 48000 to ep 0x86" in log
Also microphone on cam stops working intermittently
Behaviour was identical in Precise.

I found that a workaround for this that works (mostly) is to keep camera unpluged during boot or "wake from suspend" and repluging it in after boot.

owever this is not a surefire fix as I have seen it "triggred" random.

Unplugging and replugging the Cam helps, but tends to crash things like skype

This seems to be issue that occurs widely .
There are several references that claim that this is due to something in snd-usb-audio going wrong see here for one:
https://bugzilla.redhat.com/show_bug.cgi?id=663583

Here is a claimed workaround:
http://www.techytalk.info/logitech-e3500-webcam-and-cannot-set-freq-16000-to-ep-0x86/

I will try it...

[Claude PESTY (claude-pesty)]

Hi,

Like in previous post, seems I am still affected by the bug, although I run the latest Quantal kernel, supposed to have integrated for a while the fix released in v3.5-rc7 :

$ uname -a
Linux COYOTE 3.5.0-21-generic #32-Ubuntu SMP Tue Dec 11 18:51:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

$ lsusb
Bus 001 Device 002: ID 046d:0825 Logitech, Inc. Webcam C270

I have tons of "cannot set freq 48000 to ep 0x86" in Syslog, and the boot randomly hangs very often, more than 50% of times. The login screen appears, but without the background theme : it's all blue-purple, and the mouse and keyboard (both USB, like the webcam) are unresponsive. Sometimes it suddenly unfreezes after a while (10 to 30 seconds or so), but most of the times never : I have to hard reset the PC.
The problem disappears if I uninstall the "indicator-sound" package, which confirms, like the "unplug during boot" workaround, that the issue with Logitech USB webcam is only in startup sequence.

I am sorry but I think the bug should be reopened rather than let in the "Fix Released" status ...

[Philipp Dreimann (philipp-dreimann-deactivatedaccount)]

The original issue is, at least for me and other testers, solved.

Please bisect your issue or test a few kernel version like one before v3.5, v3.5-rc7 (where some found the issue to be solved) and maybe the current stable kernel v3.7. They should be all available from the ubuntu repositories.

I would also suggest that you open a new bug report with your findings.

Same issue here with a Logitech webcam. System hangs on startup (after entering password in gdm to start gnome 3, but gdm startup is also terribly slow), printing the "cannot set freq" messages.
Unplugging the webcam unlocks the system immediately.
This does not appear on *every* boot, could not reproduce why or why not.

[krellan (krellan-linux-kernel-bugs)]

I can confirm this bug has reappeared, as another regression. I'm running 3.8.13 (Gentoo) and this bug just started happening.

Almost exactly once per second:

[ 703.568622] 3:3:1: cannot set freq 16000 to ep 0x86
[ 704.568285] 3:3:1: cannot set freq 16000 to ep 0x86

[ 706.567485] 3:3:1: cannot set freq 16000 to ep 0x86

The desktop becomes unusable. It seems that many desktop applications, and the shell itself, are blocked on PulseAudio. PulseAudio is stuck in state "D": comatose. It's never a good sign when processes are in state "D"....

I was earlier running 3.7.10 (Gentoo) and this bug didn't happen at all back then.

Workaround is to hit Control-Alt-F1 to escape your unusable desktop, go to your text shell, start removing modules until you get rid of the offending sound driver, then hopefully that will snap PulseAudio out of its funk. Then, you can return to your desktop, and although it will be silent, you can use it again.

When the issue is happening, a recording with "arecord -d3 test.wav" takes about 11 seconds instead of 3 and playing back the recorded file gives the high-pitched / chipmunk sound mentioned above.
