  1) I have used distribution with usb support : kernel >= 2.2.18,
  slackware 7.1, Mandrake 7.2 and 8.0

  2) enable usb support test : ls /proc/bus/usb
  give you : 001/ 002/ devices driver

  3) cat /proc/bus/usb/devices
  tell you with scanner connected to USB ( normally at the end ) :
  vendor = 0x4b8 product=0x10c
  Perfection 640

  4) lsmod to see if the module : scanner is loaded
  if not you should type :
  modprobe scanner vendor=0x4b8 product=0x10c

  5) you must have device definition : /dev/usb/scanner0
  to create it : mknod /dev/usbscanner0 c 180 48
  chmod 666 /dev/usb/scanner0 ( max global permission depend on you
  )
  you can create a general link : ln -s /dev/usb/scanner0
  /dev/usbscanner

  6) you should have /etc/sane.d/epson.conf ( location depends on
  distribution )
  enable at the and of this file : /dev/usbscanner

  7) you are ready :
  scanimage -d epson --mode gray > gray.pnm : 10-20 second
  and scanner start
  scanimage -d epson --mode color > color.pnm :

  or more flexible and with preview : xscanimage

  in both cases ( scanimage and xscanimage )
  opening generated color files with
  GIMP ( other programs give error too )
  show a messagge : PREMATURE END OF FILE
  and is not possible to see.

  Best regards
