Hi, I have an ASUS A8JP Notebook with a build in webcam and I am using Ubuntu 12.04. The camera is working nice with Cheese and kernels before 3.2. I have tested the following once 2.6.32.61, 2.6.33.20, 2.6.34.11, 2.6.35.14, 2.6.36.4, 2.6.37.6, 2.6.38.8, 2.6.39.4, 3.0.94, 3.1.10. In all later kernels I have tested (3.2.50, 3.4.60, 3.10.10, 3.11.0, 3.12.0-rc1) Cheese shows for some seconds a green and noisy image and crashes then with a segmentation fault. Hans de Goede supposed that the error is caused by usb sub-system because of the errorlogs
The error logs are just a hint in the direction of this being an usb (hcd driver?) problem, my main reason for thinking that this is likely an usb problem is that the webcam driver was not changed between 3.1 and 3.2, which is where the regression occurred.
