Title:
  Regression: Logitech webcam does not work when plugged into a USB hub

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  The camera is:

  Bus 002 Device 013: ID 046d:08da Logitech, Inc. QuickCam Messanger

  I had it plugged into a USB hub, and working perfectly, but after the
  update to Natty it stopped working. If I plugged it into a front USB
  port directly, it works with Cheese.

  When plugged into the hub it has a black image in cheese, but if I
  approach my hand to the webcam, it starts working, and the image
  freezes as soon as I take my hand away from the webcam, very strange.

  In XawTV it works any way, plugged into the USB hub or directly into
  the port.
