Can you imagine, that changing D+ and D- from the USB cable solved the problem?

OK, if I now start
----[ command 'luvcview' ]----------------------------------------------
luvcview 0.2.4
SDL information:
Video driver: X11
A window manager is available
Device information:
Device path: /dev/video0
Stream settings:
Frame format: MJPG
Frame size: 320x240 (requested size 640x320 is not supported by device)
Frame rate: 20/1 fps (requested frame rate 30 fps is not supported by
device)
------------------------------------------------------------------------
OK, I get 2-4 fps now
I can get snapshoots and the video, but if I play the Video, it is
arround 10-15 times faster as the original...
So, why doees "luvcview" not set the framerate correctly in the video?
If I understand it right, "luvcview" is capturing singel images and not a
stream and it has to create a AVI from the incoming Images right?
Is there a way to correct this?
I have even tried to use VLC, but it can not even get anything.
Thanks, Greetings and nice Day/Evening
