Nah its fixed :P

Its an acer ultrabook, the devices is conencted as a usb but its not like I
can plug it of  unless I remove the LCD or something :P

I was jsut think that this might be driver related, which seems to be uvc:

% v4l2-dbg -D
Driver info:
        Driver name   : uvcvideo
        Card type     : 1.3M HD WebCam
        Bus info      : usb-/dev/usb-/dev/usb
        Driver version: 2.6.38
        Capabilities  : 0x84200001
                Video Capture
                Streaming
                Extended Pix Format
                Device Capabilities

maybe its a bug in the driver that presenting something unexpected to
/dev/video, I was just tried with ffpmeg, recompiled with v4l support and
get the same error using -i /dev/video

[video4linux2,v4l2 @ 0x80ac6f000] ioctl(VIDIOC_STREAMON): Device not
configured
/dev/video0: Device not configured
