Sane 1.0.19 Breaks Epson CX-3810 Scanner

After Slackware upgraded to Sane 1.0.19 (12.1), I could no longer access my Epson CX-3810 USB all-in-one scanner. Upon returning to Slackware's Sane 1.0.18 package (from 12.0) everything works perfectly (even with KDE 4.2's Skanlite from /testing).

/etc/sane.d/epson.conf has been correctly edited (usb 0x4b8 0x0818), and udev rules have been adjusted for non-root users. Sane-find-scanner always finds the scanner, no matter what version of Sane I'm running.

I've tried compiling Sane from source with same errors. Scanner works fine with 1.0.18 and earlier, but not even root can use the scanner under Sane 1.0.19.

I've been googling this for months, and have poured through Sane's bug reports to no avail. I can keep running the package from Slackware 12.0 until a toolchain upgrade breaks it (I usually run Slackware-current), but would like to know if anyone has any suggestions for fixing this.

Thanks to Patrick Volkerding for a great Linux experience!

I hate it when this happens....

Shortly after creating this thread, I decided to try Google one more time. I found a discussion on a Gentoo board that hadn't popped up before.

This is an older scanner that uses the epson backend. Since that backend is no longer officially maintained, Sane defaults to the epson2 backend. Commenting out epson2 in /etc/sane.d/dll.conf did the trick.

(Editing /etc/sane.d/epson2.conf did nothing)
