Hi. Thanks. 

I have tried disconnecting the printer also, trying a new cable and
another machine, the same happens all the time. I also tested the
scanner on a winxp machine, and it worked fine. Strangly, I have no
problems when I use the vuscan software under linux, but of course, I
only get $$$'s on the images..

there are no messages on /var/log/messages


I did 

	export SANE_DEBUG_SNAPSCAN=128
	export SANE_DEBUG_SANEI_USB=128

and then

	./xsane &> xsane.log

i placed the log at

	http://www.math.ntnu.no/~hrue/xsane.log.gz

the interesting part seems to be
