[sane-devel] no devices available

[jochen georges]

hello 
sorry for the newbie question on an devel-list, but i did not find the help i 
need.

i try to get my epson perfection640u (usb) scanner running with sane and 
xsane.
but xsane always says "no devices available". 
i know it should work, the scanner is supported.

i found a mini howto in the faq (it's under www.arrakis.es), i followed the 
installation-steps, but without success.

where can i find a installingguide or what do i have to do??
in the following some infos about my system.

thanks a lot in advance

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
find-scanner tool (if appropriate). Please read the documentation which came
with this software (README, FAQ, manpages).
