<P>1) I have used distribution with usb support : kernel &gt;= 2.2.18,
<BR>
slackware 7.1, Mandrake 7.2 and 8.0
<BR>
<P>2) enable usb support test : ls /proc/bus/usb
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;give you : 001/ 002/ devices driver
<BR>
<P>3) cat /proc/bus/usb/devices
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tell you with scanner connected to USB ( normally at the end ) :
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vendor = 0x4b8 product=0x10c
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Perfection 640
<BR>
<P>4) lsmod to see if the module : scanner is loaded
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if not you should type :
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;modprobe scanner vendor=0x4b8 product=0x10c
<BR>
<P>5) you must have device definition : /dev/usb/scanner0
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;to create it : mknod /dev/usbscanner0 c 180 48
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;chmod 666 /dev/usb/scanner0 ( max global permission depend on you
<BR>
)
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;you can create a general link : ln -s /dev/usb/scanner0
<BR>
/dev/usbscanner
<BR>
<P>6) you should have /etc/sane.d/epson.conf ( location depends on
<BR>
distribution )
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;enable at the and of this file : /dev/usbscanner
<BR>
<P>7) you are ready :
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;scanimage -d epson --mode gray &gt; gray.pnm : 10-20 second
<BR>
and scanner start
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;scanimage -d epson --mode color &gt; color.pnm :
<BR>
<P>&nbsp;&nbsp;&nbsp;&nbsp;or more flexible and with preview : xscanimage
<BR>
<P>in both cases ( scanimage and xscanimage )
<BR>
opening generated color files with
<BR>
GIMP ( other programs give error too )
<BR>
&nbsp;show a messagge : PREMATURE END OF FILE
<BR>
and is not possible to see.
<BR>
<P>Best regards
<BR>
