[sane-devel] sane configure in Fedora 5

[Ray Curtis]

I have a Epson 2450 usb scanner that I am trying to get to work.

First I have these rpms installed: 
sane-backends-1.0.17-5.fc5.9.x86_64
xsane-0.99-2.2.fc5.4.x86_64
sane-frontends-1.0.14-1.2.1.x86_64

I have in /etc/services:
sane-port       6566/tcp                        # SANE Control Port
sane-port       6566/udp                        # SANE Control Port

I commented out all the lines in /etc/sane.d/dll.conf except
epson

I changed /etc/sane.d/epson.conf to have the line:

usb 0x04b8 0x0112

which came from the output of scanimage -L

Then in /etc/sane.d/saned.conf I have:
192.168.1.4

the ip of the localhost which has the scanner attached.

However when I call up xsane I get the error:
Failed to start scanner: Error during device I/O

I have attached the output of : 
SANE_DEBUG_EPSON=255 SANE_DEBUG_SANEI_USB=255 scanimage -L

What have I gotten wrong here please, I used to have
this working in redhat 9 ?

Thanks,
