Hi Jean-François,
Grab does not create any toto.jpg file, instead the only text output is:
width: 640 bytesperline:640 height:480 sizeimage:921600
--> sizeimage: 921600
select timeout
lordroger@piv:~/Desktop/caca$
I've activated the debut trace with 'echo 0x3f > /sys/module/gspca_main/parameters/debug' and I've attached the kernel messages from the moment I plug the cam. I hope there's something useful in it!
Regards,

Regards,
The other possibility is that you cannot get a picture (grab stays
hung). In this case, activate the debug trace by:
echo 0x3f > /sys/module/gspca_main/parameters/debug
Then, plug the camera, do the grab and send me the kernel trace.
