I did as you suggest, then I did:

 # sane-find-scanner

and the output was: 

 found USB scanner (vendor=0x05d8, product=0x4002, chip=GT-6801) at libusb:001:003

. Then I did:

 # scanimage -h

and suddenly a TERRIBLE noise came out from the scanner, while the output was: 

 Options specific to device `gt68xx:libusb:001:003':
   Scan Mode:
     --mode Color|Gray|Lineart [Gray]
         Selects the scan mode (e.g., lineart, monochrome, or color).
     --gray-mode-color Red|Green|Blue [Green]
         Selects which scan color is used gray mode (default: green).
     --source Flatbed|Transparency Adapter [inactive]
         Selects the scan source (such as a document-feeder).
     --preview[=(yes|no)] [no]
         Request a preview-quality scan.
     --depth 8|12 [8]
         Number of bits per sample, typical values are 1 for "line-art" and 8
         for multibit scans.
     --resolution 50|75|150|300|600|1200dpi [300]
         Sets the resolution of the scanned image.
     --lamp-off-at-exit[=(yes|no)] [inactive]
         Turn off lamp when program exits
     --backtrack[=(yes|no)] [no]
         Controls whether backtracking is forced.
   Debugging Options:
     --auto-warmup[=(yes|no)] [inactive]
         Warm-up until the lamp's brightness is constant instead of insisting
         on 60 seconds warm-up time.
     --full-scan[=(yes|no)] [inactive]
         Scan the complete scanning area including calibration strip. Be
         careful. Don't select the full height. For testing only.
     --coarse-calibration[=(yes|no)] [inactive]
         Setup gain and offset for scanning automatically. If this option is
         disabled, options for setting the analog frontend parameters manually
         are provided. This option is enabled by default. For testing only.
     --coarse-calibration-once[=(yes|no)] [inactive]
         Coarse calibration is only done for the first scan. Works with most
         scanners and can save scanning time. If the image brightness is
         different with each scan, disable this option. For testing only.
     --quality-cal[=(yes|no)] [inactive]
         Quality calibration
     --fast-preview[=(yes|no)] [inactive]
         Request that all previews are done in the fastest (low-quality) mode.
         This may be a non-color mode or a low resolution mode.
     --backtrack-lines 0..255 [inactive]
         Number of lines the scan slider moves back when backtracking occurs.
         That happens when the scanner scans faster than the computer can
         receive the data. Low values cause faster scans but increase the risk
         of omitting lines.
     --gamma-value 0.00999451..5 (in steps of 0.00999451) [2]
         Sets the gamma value of all channels.
     --threshold 0..255 [inactive]
         Select minimum-brightness to get a white point
     -l 0..217mm [0]
         Top-left x position of scan area.
     -t 0..299mm [0]
         Top-left y position of scan area.
     -x 0..217mm [217]
         Width of scan-area.
     -y 0..299mm [299]
         Height of scan-area.

 Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.

 List of available devices:

. Then I did:

 # scanimage -d gt68xx:libusb:001:003 --format tiff > file.tif

, but:

 scanimage: open of device gt68xx:libusb:001:003 failed: Invalid argument

. What do you think?
Thanks indeed,
