[sane-devel] sane installation, usb

[Ingo P. Korndoerfer]

hi everybody,

can anybody give me a hint ?

i have searched through the archives and so on, but
it seems like none of the tricks give there could help me.

i am trying to install sane for my snapscan e20,
but get

scanimage: open of device snapscan:/dev/usbscanner failed: Invalid
argument

i have already downloaded and installed all these :

sane-backends-1.0.5.tar
snapscan-20011129.tar
agfafirm
snape20.bin
sanei_usb-2001-08-05.tar

the scanner module seems loaded

#lsmod | grep scanner
scanner 		4840 	0 	(unused)
usbcore                	27236   0  	[scanner usb-uhci usbkbd usb-storage]

and the usbscanner device seems there, too ...

# file /dev/usb/usbscanner0
/dev/usb/usbscanner0: character special (180/48)

what would be my problem ?

thanks

                                        ingo
