Ok.

First, above of that there must be "usb 0x05d8 0x4002".

Second, mind the capitalization of the firmware (SBfw.usb in config
file, sbfw.usb in directory). Only the latest SANE version will ignore
the case.

Third: Is the scanner detected by sane-find-scanner? If not, either
your kernel has no USB support, /proc/bus/usb is not mounted or SANE
is build without libusb support.

gt68xx.conf should alread exist in /etc/sane.d/ if you use SANE from
your distribution.

See above. This is most probably not a SANE problem because
sane-find-scanner just asks the kernel about the USB devices.

SANE uses libusb and that library looks at all USB devices connected
to the system. Devices are usually located in /proc/bus/usb/ . This
file system must be mounted (see man sane-usb).

The scanner module is not needed anymore. You just need kernel USB
support.

What's the output of "cat /proc/bus/usb/devices" and
"sane-find-scanner -v -v"?
