 I downloaded daily CVS snapshot for sane-backends from
http://www.sane-project.org/snapshots/sane-backends-2006-08-27.tar.gz
then i uninstalled previous 1.0.18 and installed this and used command
scanimage -d genesys:libusb:003:010  > pp.pnm 2>linuxlogforcvs.log
when i saw that log file i got same warmup error. here are last few
lines from my log
