I found I am able to get the scanner detected and produce scans if I run simple-scan as sudo. Am attaching simple-scan debug output from working attempt as simple-scan2.log.

Installed pkgs downloaded fron Epson-Fujitsu site as follows: iscan-plugin-gt-9400-1.0.0-1.c2.i386.rpm iscan-2.10.0-1.c2.i386.rpm Converted each to deb pkg using alien. Installed both successfully and all downloaded files seem to be in the correct folders. Modified both epson2.conf and epkowa.conf with line usb 0x4b8 0x0116 and saved. Checked /sane.d/dll.conf to see if new library file installed epkowa.conf. It was added. Still no scanner devices detected in the three programs. Scanner is on and attached to usb. Works in WinXP. Thank you.
