The kernel scanner driver in 2.5.* is usually more bleeding edge.
Currently 2.5.62 has (almost) the same driver as 2.4.21-pre4. Both
work for me, but 2.5.* gets little testing (from me). But I haven't
gotten any bug reports either.

But it seems to be connecte to /dev/usb/scanner1.

Fix the config files (plustek.conf/epson.conf).
