Not a lot :(

Well, I already saw these errors -71. One case was a cable problem.
An other one occurred with skype only, while vlc worked correctly.

So, it would be interesting to know if the (almost) last driver works.
Then, you may try the gspca-2.15.18.tar.gz from my web site:

	wget http://moinejf.free.fr/gspca-2.15.18.tar.gz
	tar -zxf gspca-2.15.18.tar.gz
	cd gspca-2.15.18
	make
	su
	make install
	reboot

You may then try cheese. For skype, don't forget to force the
use of the v4l library:

	export LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so
	skype

If the problem is still there, I'd be glad to get some traces.
For that, as root, do:

	echo 0x1f > /sys/module/gspca_main/parameters/debug

then, unplug/replug the webcam, do some capture until the problem
occurs, and send us the last kernel messages starting from the webcam
probe.

Thanks.
