# luvcview -f jpg -d /dev/video1
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video1
Unable to set format: 22.
  Init v4L2 failed !! exit fatal

Also does not work with skype. No format or other errors seen in skype. 
The only referene in strace for skype:
[pid 19901] open("/dev/video1", O_RDWR|O_NONBLOCK) = 17
[pid 19901] ioctl(17, VIDIOC_QUERYCAP or VT_OPENQRY, 0xf41d1054) = 0
[pid 19901] close(17)
I don't see any strace reference for when I try the skype camera test.

It seems the camera only works with the yuv format.
The Logitech Quickcam Pro 9000 using the same uvcvideo driver on my main 
PC works, so I shall try it on the laptop later. A gspca and a ov51x 
have both work with skype on this laptop.
Regards
Sid.
