Scanner の検出†

$ 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.

  # You may want to run this program as root to find all devices. Once you
  # found the scanner devices, be sure to adjust access permissions as
  # necessary.

• 上記結果から、権限がないことがわかる。
• scanner のデバイスファイルは /dev/sg* のどれかとなるので、パーミッションを確認する

  $ ls -l /dev/sg*
  crw-rw---- 1 root disk 21, 0  9月 13 11:08 /dev/sg0

  
  

  $ getfacl /dev/sg0
  getfacl: Removing leading '/' from absolute path names
  # file: dev/sg0
  # owner: root
  # group: disk
  user::rw-
  group::rw-
  other::---
