The group options currently do not have names set. Since only the title
is supposed to be valid for group options, this isn't a violation of
the SANE standard. Regardless, it causes scanimage (and maybe other
frontends) to skip them. Add empty name values so that they can be
processed properly.
Before:
Options specific to device `epsonds:net:n.n.n.n':
Standard:
--source Flatbed|ADF Front|ADF Duplex [Flatbed]
Selects the scan source (such as a document-feeder).
--mode Lineart|Gray|Color [Color]
Selects the scan mode (e.g., lineart, monochrome, or color).
--depth 1|8bit [8]
Number of bits per sample, typical values are 1 for "line-art" and 8
for multibit scans.
--resolution 75|150|300|600|1200dpi [75]
Sets the resolution of the scanned image.
-l 0..215.9mm [0]
Top-left x position of scan area.
-t 0..297.18mm [0]
Top-left y position of scan area.
-x 0..215.9mm [215.9]
Width of scan-area.
-y 0..297.18mm [297.18]
Height of scan-area.
--eject [inactive]
Eject the sheet in the ADF
--load [inactive]
Load a sheet in the ADF
--adf-skew[=(yes|no)] [inactive]
Enables ADF skew correction
--adf-crp[=(yes|no)] [inactive]
Enables ADF auto cropping

The OPT_ADF_CRP (adf-crp) option is detectable from the hardware and is
settable as an option, but can't be queried. This appears to just be an
oversight, so add it to the list of handled options.

Subject: [sane-devel] Additional model support for epson2 / epsonds backend

Backends use a mixture of SANE_CURRENT_{MAJOR | MINOR} and V_{MAJOR |
MINOR} with all kind of permutations. I was confused by this and one
comment in pieusb.c tells me I was not alone. Some items in old
changelogs suggest to use the SANE_CURRENT_ macros in backends, so let's
switch to do that with the exception of net.c and dll.c. Done with:
$ find backend -name '*.[ch]' | xargs sed -i '/nearly every/ ! { s/\<V_M/SANE_CURRENT_M/g }'
$ git checkout backend/net.c backend/dll.c
And manually removing the comment from pieusb.c. Everything still builds
fine.
Certain backends do network scans even if the 'local_only'
parameter for 'sane_get_devices()' is true. Fix that.
Changes:
1. Modify 'sanei_configure_attach()' so that backend specific
data may be passed to the 'attach()' function.
2. Use this in certain backends to pass the value of the
'local_only' parameter so that network related activities
are only carried out when the value is false.
If the value to be set is not valid, it should not change the sval
structure (even if doing so has no negative side effects).
This also makes the fallthrough less confusing by removing the first
cast of two for the br-x and br-y values.
