That is not necessary.

I get the feeling that you misunderstand the intended purpose of the
sane-find-scanner command. If scanimage -L lists your scanner, you have
no need for sane-find-scanner at all. Seeing that you can use the SX400
with simple-scan and xsane, you are all set.
Don't worry about the NX400 in the output. Epson (and probably other
manufacturers as well) has a habit of marketing the same device under
different names in different parts of the world. The database used by
lsusb only knows about PX-501A and Stylus NX400.
Just search the list of devices supported by external backends such
as the epkowa backend for 0x04b8/0x084a and you'll find: PX-501A, Stylus
NX400, Stylus SX400, Stylus SX405 and Stylus TX400. From a USB device
perspective, these are all the same.

See, the epkowa backend knows about most of the other ones. But hey, it
the device works, who cares (much) about what the various tools think
they are dealing with and what in printed on your device ;-)
