epson backend for the Stylus CX4800

Hello,

a user reported to us that the Epson Stylus CX4800
(0x4b8/0x419)
works perfectly with the epson backend if the USB IDs are
added to epson.conf, see
ht
tps://bugzilla.novell.com/show_bug.cgi?id=206428

Up to now it seems only the epkowa backend (version 2.1.0)
knows about this model, see
http://www.sane-project.org/cgi-bin/dri
ver.pl?manu=epson&model=cx4800

Kind Regards
Johannes Meixner

Unless there is yet another USB product ID I've never heard
of, I
think that should be 0x4b8/0x819.  At least, that's what's
in
epkowa.desc

On a related note, I recently discovered that, even if you
don't need
a binary-only non-free plugin, not all epkowa supported
devices work
with the epson backend.  In my case, this happened with a
PM-A750 (aka
Stylus Photo RX520/530).  I haven't really looked into it
but if first
impressions are anything to go by it may have to do
something with the
(not) sending of the ESC i command and the processing of its
reply.

# Me goes back to work ...

Hope this helps,

You are right.
There was a typo of the user.
His Epson Stylus CX4800 has 0x4b8/0x819.
Thanks a lot for pointing out the error!

sane-find-scanner shows it as
"vendor=0x04b8 [EPSON], product=0x0819 [USB2.0
MFP(Hi-Speed)]"
note the user-friendly USB model string 

For details (like "lsusb -v" for his scanner)
see
https://bugzilla.novell.com/show_bug.cgi?id=206428#c3

Point well taken and I also wish it would be more
informative but I'm
afraid there not much that can be done about it.  Even the
firmware's
scanner part only says CX4800 which is not very helpful if
you bought
it someplace where it is marketed as a Stylus CX4700, Stylus
DX4800 or
even PX-A650 ...

Hey, at least the vendor specific interface mentions:

   iInterface              5 EPSON Scanner

;-P

Hope this helps,
