artec 48+U scanner & xsane

[hbrhodes]

okay, i modified the artec_eplus48u.conf file and trimmed it up so it 
only contains information about my scanner, i'm using the usb version, 
so i think i have it right but it still won't work; merely replies with 
invalid argument.  i'm certain this will work if i or someone else 
(anyone!) can figure it out and post their answer!
