If that also happens after you unplug/replug the scanner one reason
may be the kernel USB scanner module. Try lsmod, does it list
"scanner"? And have a look at /proc/bus/usb/devices: Does it list your
scanner with "driver=usbscanner"? If yes, the kernel scanner module
claimed your scanner.

That's not a problem because it's also possible to use the kernel
scanner driver. Maybe you don't have the necessary devices like
/dev/usb/scanner0? Running "MAKEDEV usb" in /dev should help.

If that's not the problem, disable everything but gt68xx in dll.conf
and send a more detailed log:

SANE_DEBUG_GT68XX=255 SANE_DEBUG_SANEI_USB=255 scanimage -L

Bye,
