Ok, found one of my mistakes: missing libusb-devel and now I have
compiled the latest sane-backend (sane-backends-git20110215) with
configured libusb- support (./configure --enable-libusb_1_0).

Now I have same problem as "normal" user: no scanner found. With root-
access I get: "Error while accessing device 'libusb:001:018': Unknown
argument" (Sorry if this is not the same like native english error
message, because I translated this from german error message! :-) )
Everytime I try to access the scanner as root, the device identifier is
increased after this error message (001:010 was displayed in first message)!

Now I got more output in logfile (take a look at attachted logfile)!

What is next?
