Regarding "'artec_eplus48u", here is the manual working solution for
Ubuntu 10.10 (possibly also applicable to Ubutnu 10.04 and some versions
before that, down to year 2007, according to web sites).
After doing:
sane-find-scanner
, this is the result for a MEDION MD4394:
found USB scanner (vendor=0x05d8, product=0x4003, chip=GT-6816) at
libusb:003:002
Keep in mind, there are possibly two different revisions of this scanner
family.
===> Solution 1 (possible first revision):
This scanner might be possibly misidentified to work with the gt68xx driver
(http://www.meier-geinitz.de/sane/gt68xx-backend/). The procedure should be, to
add following lines to the end of /etc/sane.d/gt68xx.confm to perform manual
override:
usb 0x05d8 0x4003
override "artec-ultima-2000"
firmware "Artec48.usb"
Also, the firmware is required!!!!!! It must be placed in
/usr/share/sane/gt68xx/ .
After that, the scanner in question responds, but may stall or make weird
noises due to be variant 2 chipset.
===> Solution 2 (worked in my case):
More probable match is the artec_eplus48u backend.
The file /etc/sane.d/artec_eplus48u.conf must be modified. Add the end, add
this:
# --------------------------------------------------------------------------
# MD4394 test
usb 0x05d8 0x4003
option artecFirmwareFile /usr/share/sane/artec_eplus48u/Artec48.usb
option ePlusPro 1
option vendorString "Artec"
option modelString "MD 4393"
Also, the firmware is required!!!!!! It must be placed in
/usr/share/sane/artec_eplusu/ .
===> Also - possible backend override may be neccessary:
/etc/sane.d/dll.conf must possibly be modified.
In my case, it loaded automatically the unmatching in the list (gt68xx), which
was wrong match. So comment out this line :
gt68xx
into
#gt68xx
and artec backend will be used instead.
===> Also - firmware is mandatory:
Firmware can be, for example, gotten from windows CD (in the driver directory,
usually the file with extension .usb). It is neccesary to exist in the correct
/usr/share/sane subdir, in order for the scanner to work.
Firmware name might diffe, keep that in mind. But usually has an extension .usb.
===> Suggestion:
I suggest, that sll this, now done manually, should be made somehow
automatically working in Ubuntu in future (i.e. a wizard with possible
subtypes, when this PID is detected). This would make life easier,
===> Other distros:
The procedure is the same for other distros with sane, except the location of
firmware and sane config dirs might differ.
