The subject device is not listed in the SANE backend directory. It is a
5Mp photo scanner with a USB interface. I suspect it would work quite
well if I lie to SANE about what it is, if I can identify a similar
supported device. Any suggestions? (USB id 0feb:2015)

hink that emphasizing a Web interface
over a plain email interface for an /email/ mailing list is just plain
wrong. Perhaps the list should include the email unsubscription address
in the footers as well.

I'm sure your facts are correct. But the original poster said that
scanimage -h returned halftone as an option. If the driver doesn't

I've been told that two chips are involved, a PAL16R8 and a GL640USB_40SOJ.
As at least one of those is programmable, and could be programmed uniquely

According to the directions on Lexmark's web site, that file is intended

The one we have is SCSI. We paid about US$1200.

ize; scanning 100 inches when the actual size
is maybe 22 inches is not a good idea.
It is our desire to contribute this backend to the SANE project once it
is mostly working. However, I'm not sure that will be of much benefit
since it uses a non-standard interface (not USB or SCSI) and we
, ignoring the initial value
set by the backend. This is true even if no .drc file exists.
Why? Do I have to list the resolutions in reverse order to make it work
properly with xsane? If so, what's the point of an initial default?

ow, can't tell and reports success, so the
backend doesn't know it should first request sense and then retry.
Of course, I can just guess and always retry. But that is far from
efficient, especially since there is a 60-second timeout involved.

frontend tries to call sane_open(), there is no valid device name and
sane_open() reports SANE_STATUS_INVALID. This is misleading at best.

hardward realm by limiting the choices. But I do think we could be a

lows a frontend to request a
specific read size. Yes, it's called a maximum buffer size, but the
implication is that that is the optimum size transfer for the frontend.
A properly written backend should attempt to honor that request and not
respond with less without a good reason.

reading another block whenever necessary, and only returning a short
