[sane-devel] no scanners found (leo s3 scsi-scanner)

Hi,

thanks for your answers.

But sane-find-scanner -v -v shows not a 0 behind the scanner name:

searching for SCSI scanners:
checking /dev/scanner... open ok
  Inquiry for device:

  # Your SCSI scanner was detected. It may or may not be supported by

searching for USB scanners:

 # No USB scanners found. If you expected something different, make sure 
that
  # you have loaded a driver for your USB host controller and have 
installed a

  # Scanners connected to the parallel port or other proprietary ports

  # detected by this program.
done

Have I to do anything in the sourcecode ?

Bye
Axel
