With my scanner at home I get the following

- starting xsane:
	no message in /var/log/messages (I guess
	explainable from the above message in the
	last line)

Sorry for the long tail output, but I don't
know what's really relevant and I hope, that
Mozilla doesn't produce any uncomfortable
linebreaks. BTW: usb.-uhci ends up with
the same message.

Greetings,
