But anyway, here are results (and question still stands - is there any way to speed up scanning process; difference becomes hours for hundreds of images): $ uname -a #(+ HPS' USB stack revision 538) FreeBSD host01 6.2-STABLE FreeBSD 6.2-STABLE #1: Wed Aug 1 05:45:10 MSD 2007 root@host01:/usr/obj/usr/src/sys/HOST01 i386 $ uname -a FreeBSD host01.localdomain 7.0-CURRENT FreeBSD 7.0-CURRENT #0: Thu Jul 26 07:45:03 MSD 2007 root@host01.localdomain:/usr/obj/usr/src/sys/GENERIC i386 $ uname -r 6.2-STABLE $ time scanimage -p --mode color --resolution 600 --quick-format max > /PUBLIC/TMP/000-DEL/6_2-600-max01.pnm Progress: 100.0% real 0m40.984s user 0m3.414s sys 0m0.821s $ uname -r 7.0-CURRENT $ time scanimage -p --resolution 600 --quick-format max --mode color > /PUBLIC/TMP/000-DEL/7_0-600-max01.pnm Progress: 100.0% real 0m56.550s user 0m3.729s sys 0m0.597s $ uname -r 6.2-STABLE $time scanimage -p --mode color --depth 16 --resolution 600 --quick-format max > /PUBLIC/TMP/000-DEL/6_2-600-16-max01.pnm Progress: 100.0% real 1m4.007s user 0m7.485s sys 0m1.731s $ uname -r 7.0-CURRENT $ time scanimage -p --mode color --depth 16 --quick-format max --resolution 600 > /PUBLIC/TMP/000-DEL/7_0-600-16-max01.pnm Progress: 100.0% real 1m40.989s user 0m7.606s sys 0m1.238
