when you run scanimage with no -d argument, sane will load all the
backends that are listed in the dll.conf file, in an attempt to find your
scanner. you can look for this file in /etc/sane.d or similar, and # out
all the options other than the backend you are using. this should fix the
as to the timeouts, that could have any number of causes, but seems really
common with 2.6.x can you switch back to a 2.4 kernel just to test?
