Karl, I also noticed that Epson's ISCAN GUI no longer works after installing the SANE 1.0.12 backend. ISCAN has a setting for threshold, so it is probably the same bug. Using scanimage directly (not via my code) only works if the threshold option is not used, so I doubt it's my code. Also, "scanimage --help" shows that the threshold option is inactive, so the problem is probably somewhere in the initialization code. BTW, I'm using kernel 2.4.20 (RedHat 7.3 and Slackware 8.1) and USB 1.1.
