Public bug reported:
After doing a kernel upgrade on my Ubuntu 12.04 LTS system from 3.2.0-63
to 3.2.0-64, USB 3.0 cameras have stopped working properly. I use the
application guvcview to preview the cameras. The initial preview when
starting the application works fine. But when trying to change the
resolution of preview, the application reports an error continuously for
each frame.
Description: Ubuntu 12.04.4 LTS
Release: 12.04
guvcview:
Installed: 1.5.3-0ubuntu1
Candidate: 1.5.3-0ubuntu1
Version table:
*** 1.5.3-0ubuntu1 0
500 http://archive.ubuntu.com/ubuntu/ precise/universe i386 Packages
100 /var/lib/dpkg/status
cat /proc/version_signature
Ubuntu 3.2.0-64.97-generic-pae 3.2.59
Steps to reproduce:
$ sudo apt-get update && sudo apt-get dist-upgrade && sudo apt-get install
guvcview -y
$ sync
$ sudo reboot
Connect any USB3.0 superspeed camera available on the market to an USB 3.0 port
on your system.
I am using an e-con system's See3CAM_80 USB 3.0 camera.
Now start the application guvcview from a terminal window
$ guvcview
The application starts up showing the GUI for controls and another
window showing the preview. Now try to change the resolution of the
camera by using the "resolution" combo box present in Video tab of the
application controls window.
What I expected to happen :
The preview resolution should have changed to the selected resolution.
What happened instead :
The preview window becomes black and no more frames are obtained from the
camera. The terminal window shows the following errors repeatedly.

and so on...
Restarting the application also doesnt work. Only after disconnecting and
reconnecting the camera, I am able to see the preview properly.
The workaround is to revert to kernel 3.2.0-63. After that the
application is working fine and switching to other resolutions also work
properly.
