problem to get Vuescan software work with Hewlett Packard HP Scanjet N6310 scanner

could is be a USB2/3 problem ? i use here a pretty old Dell Optiplex 980 SFF but i didn't play yet in its BIOS with USB settings (in case there is such).

Your dmesg output didn't suggest any problems, and confirmed that the host controller was using the ehci-pci driver consistent with USB 2.0 ports.

I've always assumed that VueScan developed its own drivers, and didn't rely on sane drivers. Where does it add value if that's not the case?

I note that the N6310 model is still listed as "Not supported yet"

Code:

# cat /usr/share/sane/descriptions/genesys.desc|grep N6310 -A4
:model "ScanJet N6310"
:interface "USB"
:usbid "0x03f0" "0x4705"
:status :untested
:comment "Not supported yet"

Your best bet to help progress support is probably to engage with the developers via a mailing list...

yes, i thought so too, but then i received this :

Unfortunately, if SANE doesn't work with this scanner, VueScan won't either.

moreover, i saw this too :

:comment "Not supported yet"

but that was for SANE version 1.0.24 : http://www.mideiros.net/doc/system/p...html#S-GENESYS
while i was hoping that the newest version 1.0.27 would do a better job on the N6310... perhaps it depends on the chipset ? i bought mine in the US back in 2014.

i think, you are right, i should contact the developers.

is this perhaps a python v2/3 problem ? i have both versions installed.

No personal experience on this, but this may help for HPLIP

thanks, allend, but as said earlier :

regarding hplip, it's only good for HP printing devices or a combination thereof, but is of no use for HP's scanner-only devices.

the N6310 is a scanner-only device.

my only hope is that the SANE developers can help here. does anybody know their contacts and email lists ?

Is your user a member of the 'scanner' group?

PS - Recommended groups for a user are:
users lp audio video cdrom plugdev power netdev scanner

pisti · 03-13-2018, 08:28 AM

yes, users is member of 'scanner' and 'lp'.

then - see below - my other scanner, a Fujitsu ScanSnap, works just fine with imagescan/sane/xsane/Vuescan. i believe it's a specific HP Scanjet N6310 problem for SANE.

From /etc/sane.d/genesys.conf on my Slackware-current system

Quote:

# genesys.conf: Configuration file for Genesys Logic GL646 and GL841 based scanners

#
# scanners that are not yet supported
# uncomment them only for development purpose
...
#Hewlett Packard ScanJet N6310
usb 0x03f0 0x4705

It would appear that the device is supported by SANE in the sane-1.0.27 package in -current.

The device is shown as unsupported in sane-1.0.24 https://www.chiark.greenend.org.uk/d...supported.html

pisti · 03-13-2018, 08:54 AM

thanks, allends, i saw that 'chiark' link too, but see the newest SANE-GENESYS list here :
http://www.sane-project.org/sane-bac...html#S-GENESYS
the N6310 is still "Untested - Not supported yet".

anyway, i just joined the SANE mailing list...will see.

I refer you to the notes for the 1.0.27 release. https://alioth.debian.org/frs/showno...elease_id=2061

New with 1.0.27 (see Note 1), released 2017-05-22:

* Significant enhancements to canon_dr, epjitsu, epsonds, fujitsu,
genesys, hp3500, pixma and xerox-mfp backends
* Minor updates, bugfixes or scanners added in several backends.

pisti · 03-13-2018, 09:48 AM

actually, i am using SANE/GENESYS already under 1.0.27, but in the N6310's case without success.

the link in my last reply was also about the 1.0.27 version - http://www.sane-project.org/sane-backends.html - showing "Untested - Not supported yet".

do you have a N6310 up & running under linux/SANE ?

ferrari · 03-13-2018, 12:45 PM

For sane-backends-1.0.27, although the genesys backend does list the N6310 chipset, the /usr/share/sane/descriptions/genesys.desc that comes with the package describes it as 'untested' and 'Not yet supported', so as I've already stated, contacting the SANE developers would be a good idea.
