Hello! I trying to use an EPSON 640U with sane 1.0.18+cvs20061127-1.
The platform is a WL500gp running Oleg?s firmware (Linux 2.4.20/mips). I have sane-backend installed and ?scanner.o? module is recognizing the scanner: ... scanner.c: USB scanner device (0x04b8/0x010c) now attached to scanner0 scanner.c: 0.4.16:USB Scanner Driver sane-find-scanner results: ... found USB scanner (vendor=0x04b8, product=0x010c) at /dev/usb/scanner0 ... Access rights to /dev/usb/scanner0 are fine ? a ?SANE_DEBUG_EPSON='255' scanimage ?L? results: [sanei_debug] Setting debug level of epson to 255.

If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages).
