Thank you, after many trials, I am sure that my USBs are USB2, that the 
scanner works with Windows.
So I thnk there is a problem with genesys handler. I have traced  :

[genesys] sane_get_option_descriptor: option = br-y (11)
[genesys] sane_control_option: start: action = set, option = br-y (11)
[genesys] sane_control_option: exit
[genesys] sane_genesys_start start
[genesys] genesys_start_scan start
[genesys] genesys_restore_calibration start
[genesys] genesys_flatbed_calibration
[genesys] sanei_genesys_calculate_zmode2: two_table=0
[genesys] genesys_flatbed_calibration: led calibration failed: Error 
during device I/O
[genesys] genesys_start_scan: failed to do scanner calibration: Error 
during device I/O
[genesys] sane_genesys_start: Error during device I/O
scanimage: sane_start: Error during device I/O
[genesys] sane_genesys_cancel start
[genesys] sane_genesys_cancel completed
[genesys] sane_genesys_close start
[genesys] write_calibration start
[genesys] write_calibration completed
[genesys] sane_genesys_close completed
[genesys] sane_genesys_exit start
[genesys] sane_genesys_exit completed
FAILED

Any help welcome...
