  No. You can probe for devices while Linux is running. Just issue the
  following command as root:

  echo "scsi add-single-device 0 0 4 0" > /proc/scsi/scsi

  ... that's for my system, where the scanner is attached as device number
  four on the first adapter. Just replace the "4" with the ID of your
  scanner.

  If you want to power down the scanner without rebooting you have to
  remove the scanner first from the SCSI system by using the following
  command (again, this is for device number four, just use your ID):

  echo "scsi remove-single-device 0 0 4 0" > /proc/scsi/scsi

  Again, this is not necessary: Let's assume, that your scanner is
  connected as device number four, therefore it will show up as
  /dev/sg4. The file mode on this device is what lets you scan, or
  what gives you the error message when xscanimage is not setuid root.
  So if you create a new group "scan" and make yourself a member of this
  group and set the group of the /dev/sg4 device file to "scan", and
  set the file mode to 660 you can scan without having xscanimage be
  setuid root.

  BTW: Check out xsane, which is a much better frontend than xscanimage.
  You can find it at http://www.wolfsburg.de/~rauch/sane/sane-xsane.html

  Your scanner is not used with all it's capabilities if you are using
  Sane "out of the box". There is a better backend available from
  Christian Bucher at http://www.vernetzt.at/~bucher/Epson/Epson.html
  Read the installation instructions and if you have any questions
  regarding the installation, ask me. Don't bother Christian too much
  so that he can use his time for making his software even better :-)

  Have fun scanning,

  Karl Heinz
