Hi,

I have a Plustek SmartOffice PL1500 ADF scanner, do not work out of the
box, I would like to help to get it supported.
http://plustek.com/uk/products/workgroup-scanners/smartoffice-pl1500/

It's not referenced here : http://www.sane-project.org/sane-mfgs.html so
I asked for an addition here : http://www.meier-geinitz.de/tinc
It doesn't have either closed source drivers for Linux, drivers are
available from Windows XP to 10 and are "Twain compatible".

Some infos :
$ sudo sane-find-scanner
found USB scanner (vendor=0x07b3 [PLUSTEK INC], product=0x0c1f [USB2.0
SCANNER], chip=GL843) at libusb:001:010

I use Ubuntu 16.10 with sane-backends Version: 1.0.25+git20150528-1ubuntu2

sane-genesys man page say that GL843 is supported (
http://manpages.ubuntu.com/manpages/yakkety/man5/sane-genesys.5.html )
So I tried to add support for it by following those basics steps :
https://help.ubuntu.com/community/SANE%20-%20Installing%20a%20scanner%20that%20isn%27t%20auto-detected

That doesn't helped.


This command may give interesting infos :

$ SANE_DEBUG_GENESYS=255 scanimage -L
[genesys] attach: vendor 1971 product 3103 is not supported by this backend
1971 and 3103 are decimal values of vendor and product ids .

Could anyone help me ?
Thanks
Quentin B.

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

# Your USB scanner was (probably) detected. It may or may not be
supported by
# SANE. Try scanimage -L and read the backend's manpage.

# Not checking for parallel port scanners.

# Most Scanners connected to the parallel port or other proprietary ports
