Bug Description

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.

This issue still occurs in the latest version of kernel for Ubuntu 12.04 LTS as of date. (ie. 3.2.0-65)
cat /proc/version_signature

Ubuntu 3.2.0-65.98-generic-pae 3.2.60

I have tested and confirmed that this issue can be recreated, not only in my PC but also in other PC's with different hardware configurations.

If you need any more information for debugging please let me know.
