I use both kernels in Ubuntu 12.04, and the camera works with the older one, so I filed the bug here as I don't know when it stopped working. The camera is still recognized by v4l2, properties can be accessed by v4l2-ctl for example, and seemed correctly reported back (pixelformats for exmaple match my expectation). But the frame capturing intself will always fail with 'device busy'. Usb IDs: 04f2:b221 Chicony Electronics Co., Ltd integrated camera What further information would be useful?
