Does anyone know what this means, i don't have a clue.
I noticed that the led in my cam does lit for a sec, so i am on the right way... ;)

By the way when i run webcam:
i become the following output, which looks ok:
video4linux webcam v1.5 - (c) 1998-2002 Gerd Knorr
grabber config:
size 320x240 [24 bit TrueColor (LE: bgr)]
input (null), norm (null), jpeg quality 75
rotate=0, top=0, left=0, bottom=240, right=320
webcam 2004-01-18 17:33:27
webcam 2004-01-18 17:33:30

Led is lit in this case and cam is running.

Thanks for any support!

Ron,
try to set 160x120 pixels capturing dimension and YUV420P palette. Without YUV420P my quickcam doesn't work. You might also set the maximum fps speed to 5 fps, for example, and buffers to 25, 5, 5, 5. I also had some problems at the beginning but with those settings I have quckcam working without a problem. If this works you can work it up and see which setting makes the problem.

Regards,
Darko
