Debian Stretch: Scanner and Sane

For old scanner like my Umax 3450, it is impossible to get windows x64 driver. Its driver only available for windows 32. Manufacture refuse to build windows x64 driver.
But it does not matter in Linux in my case Debian. It will available in both Debian x64 and x32.

Use Sane to detect your scanner

# sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.
