It seems what the SANE database online shows at http://www.sane-project.org/cgi-bin/driver.pl?manu=&model=3180&bus=any&v=&p= is a contradiction in itself: It lists the HP Photosmart C3180 as explicitly "unsupported" by SANE (actually the device is listed for the "unsupported" backend) but also as "good" supported by the external backend "hpaio" which is provided by HP's HPLIP software, see http://hplipopensource.com/hplip-web/models/photosmart/photosmart_c3100_series.html I think that devices which are supported by an external backend should not be listed for the "unsupported" backend in SANE. I think the "unsupported" backend in SANE is only for devices which are known to be neither supported by a built-in backend in SANE nor by an external backend for SANE. At least this is how I understand the "Comment" for the "unsupported" backend in SANE: ------------------------------------------------------------------ Backend: unsupported ... Comment: The devices mentioned here are not supported by any SANE backend. However, there may be links to information about them or stand-alone programs. ------------------------------------------------------------------ For me "any SANE backend" means both built-in backends in SANE and external backends for SANE. In contrast a real built-in backend in SANE like "hp" might list the HP Photosmart C3180 with status "unsupported" in compliance to what a particular backend's status "unsupported" for a particular device means: ------------------------------------------------------------------- Legend: ... Status: ... unsupported means the device is not supported at least by this backend. It may be supported by other backends, however. ------------------------------------------------------------------- Kind Regards Johannes Meixner -- SUSE LINUX Products GmbH, Maxfeldstrasse 5, 90409 Nuernberg, Germany AG Nuernberg, HRB 16746, GF: Markus Rex
