fix for iSight cameras not being recognized

Specifically fixes this error message:

Mar 22 18:52:27 localhost kernel: [ 9417.193438] uvcvideo: Unknown video format 32595559-0000-0010-8000-000000359b71

Mar 22 18:52:27 localhost kernel: [ 9417.198737] usbcore: registered new interface driver uvcvideo

I'm new to this and I apologize greatly if this is the wrong place to ask this, but this bug is one of two things driving me up a wall trying to use Ubuntu on my Macbook Pro (the other is the trackpad feel, since you can't hold the button with one finger and drag with the other)... and I see that it's fixed upstream somewhere and I'm wondering if I could get directions on how to fix this on my system? Again, I know this isn't the place to ask that kind of direction but I'm not sure where is - my email is <email address hidden> if anyone wants to contact me with that. Thank you all very much for any help, Mark

Hi Michael,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Seems there's 2 issues here:
1) sometimes occurring independently
May 26 08:41:05 ridgerunner kernel: [ 14.262710] uvcvideo: Unknown video format 32595559-0000-0010-8000-000000359b71

May 29 08:04:16 ridgerunner kernel: [ 12.893939] usbcore: registered new interface driver uvcvideo

2) sometimes they coincide
May 24 08:48:33 ridgerunner kernel: [ 12.729848] uvcvideo: Unknown video format 32595559-0000-0010-8000-000000389b71

May 24 08:48:33 ridgerunner kernel: [ 12.729892] usbcore: registered new interface driver uvcvideo

#1 the video format issue (this bug, listed as a dup of 544469 but I think is not)
#2 no valid video chain (bug 544469)

Both problems seem to be fixed upstream: MacBookPro5,5 with 2.6.34 kernel (note Cheese seg faults so use something else)

Grr! Nevermind. First few reboots were just lucky. I've since seen both problems with kernel 2.6.34

Jeremy, I did test the latest upstream release. This was fixed in commit 68f194e0 in the mainline Linux kernel tree.

Michael,
    Since that is only a part of the SHA1 I need to ask, Is that for
commit 68f194e027ecfbbc8d5515bc40787e542eed59e9 ?

Thanks!

Jeremy, yes. Full SHA1 is 68f194e027ecfbbc8d5515bc40787e542eed59e9

Indeed, this patch is already in the upstream kernel as of 2.6.34-rc1:

linux-2.6$ git describe --contains 68f194e027ecfbbc8d5515bc40787e542eed59e9
v2.6.34-rc1~280^2~347

The actively developed Ubuntu Maverick kernel was recently rebased with the latest 2.6.35-rc5 mainline kernel and thus already contains this fix. I'm therefore marking the actively developed linux kernel task as Fix Released. I'll go ahead and approve the Lucid nomination for this to be considered for a Stable Release Update for Lucid. Thanks.

Hi Michael,

Before I submit this patch to upstream stable to then be pulled back into Lucid as an SRU, I'd appreciate if you could test the following kernel I've built:

http://people.canonical.com/~ogasawara/lp544740/amd64/

It's the latest Lucid kernel with the upstream patch applied. I just want to verify this patch indeed resolves the issue on a Lucid kernel (ie 2.6.32 based). Please let me know your results. Thanks.

This does fix this particular bug (not recognizing the iSight camera), but there unfortunately are still more problems with the uvcvideo driver for this camera (No valid video chain found). Here is output from doing "rmmod uvcvideo && modprobe uvcvideo trace=15" using your kernel:

Hi Michael. Thanks for testing and the feedback. Care to open a separate bug for this new issue you are seeing. Thanks.

For now, I've gone ahead and submitted commit 68f194e027ecfbbc8d5515bc40787e542eed59e9 to upstream stable for consideration. Assuming it's accepted for the next 2.6.32.y stable update, we'll then get this in Lucid when we pull in the next 2.6.32.y stable patch set. Thanks.

Should be fixed now in Lucid with the latest 2.6.32-25.44 kernel:
