Edit the /usr/local/sane.d/epson.conf to reflect the usb info 
instead of the pt_par info, and mv plustek.conf to something else 
to prevent needless confusion.

One thing I've found helpfull is to add the ident numbers to the 
list of such numbers in the kernel sources at drivers/usb/scanner.h 
and rebuild the kernel.  dmesg will then show the correct data on 
the usb hub scan making everything else a bit more automatic.
This an also be done with suitable entries in modules.conf, but I do 
things the hard way I guess just to keep in practice. :-)
