[Christopher M. Penalver (penalvch)]

Sezer Yalcin, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-fixed-upstream-3.18-rc7

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

The problem is a wrong "bytesperline" parameter set in vc032x.c

[Christopher M. Penalver (penalvch)]

Luca, upstream accepts direct patch submissions on the relevant mailing list (in this case linux-media CC Hans de Goede as per http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/MAINTAINERS ). Bugzilla and Launchpad wouldn't be the best venue for submitting patches to upstream directly. Could you please post it to them and advise of the URL to your post?

[Sezer Yalcin (sy-y)]

Hi Luca, anything I can help with this?

[Luca (lucabon-1)]

Hi Sezer,
  I already submitted the patch to the linux-media related mailing list. But... I really don't know how many time it will take to be included in official Ubuntu kernel...

In the while, you can patch by yourself your kernel. Login as root (sudo su -), and then:

 apt-get build-dep linux-image-`uname -r`
 apt-get source linux-image-`uname -r`
 cd /usr/src/linux-3.13.0/drivers/media/usb/gspca
 wget https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1400164/+attachment/4296240/+files/vc032x.diff
 patch vc032x.c vc032x.diff
 make -C /usr/src/linux-headers-`uname -r` M=`pwd` gspca_vc032x.ko
 cp gspca_vc032x.ko /lib/modules/`uname -r`/kernel/drivers/media/usb/gspca/
 rmmod gspca_vc032x
 depmod -a
 modprobe gspca_vc032x

Start you favorite application, and the camera now should work correctly!

If the kernel will be upgraded, you have to make another time all the steps if the main kernel release changes (e.g., if you will get 3.16.0), otherwise you should do only the following steps:

 cd /usr/src/linux-3.13.0/drivers/media/usb/gspca
 make -C /usr/src/linux-headers-`uname -r` M=`pwd` gspca_vc032x.ko
 cp gspca_vc032x.ko /lib/modules/`uname -r`/kernel/drivers/media/usb/gspca/
 rmmod gspca_vc032x
 depmod -a
 modprobe gspca_vc032x

Ciao!
  Luca
