[sane-devel] Epson 640U and sane1.0.18+cvs20061127-1

[Bjoern Daehn]

Hello!

I trying to use an EPSON 640U with sane 1.0.18+cvs20061127-1.

The platform is a WL500gp running Oleg¹s firmware (Linux 2.4.20/mips). I
have sane-backend installed and ³scanner.o² 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 ³SANE_DEBUG_EPSON='255'
scanimage ­L² results:

[sanei_debug] Setting debug level of epson to 255.

No scanners were identified. 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).
