[Bug 1322380] [NEW] No webcam functionality with 1d6b:0001 Zoran Microelectronics, Ltd Digital Camera EX-20 DSC

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Same as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/630568

Not a regression. This has been happening since 8.04 and I have
personally tested it with every version since 12.04.

dmesg reports the following additional output after plugging the camera.
You can see where I change the camera to "PC Mode" (in order to use the
webcam, users must do this from the camera) at [  691.147589]. The
device is turned off at [ 1094.746444].
