We have the same OS and the same scanner. I am trying to make it work on FC2.
You dont really need to modify /etc/module.conf, at least at the beginning.
But yes no more /etc/module.conf in FC2.
Anyway, first manually, I did :
[root@P4 root]# modprobe scanner vendor=0x04b8 product=0x010f
FATAL: Module scanner not found.
I try to use iscan from epkowa. This was working good in RH9.
I will give more news if I find the way to fix it.
