  1d6b:0001 [MSI A55M-P33] No webcam functionality with Zoran
  Microelectronics, Ltd Digital Camera EX-20 DSC

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  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]:
