Hi,
first of all: The scanner works when I connect the PCMCIA-USB adapter to
the AC/DC adapter -- Thanks much for this hint!

This is the end of the xsane trace -- look in scanimage.zip

How can I determine this?

No other devs are connected to the USB adapter. But as soon as I connect
the AC/DC adapter of the PCMCIA-USB adapter everything is fine.

Backtracking still occurs at 600 dpi and higher but the pics are nice. In
other words, there is a solution for the seg fault problem by plugging in
the power cable of the USB adapter. Anyways, an error message instead
would be nice in order to enable the user to solve the problem.
HTH & thanks for your helpful responses!
