it does work with VLC but not with gstreamer because of the missing v4l2ctl

Does the v4l2 do work with your camera at all? Or does the camera work at
all?
For instance: does the program qv4l2 give any images? Or does $v4l2-ctl -L 
give you any results?
(programs are in the packages: qv4l2 and v4l-utils)
