[sane-devel] saned does not find hpaio scanner

[martin f krafft]

Hey,

We have a scanner available through a network and since we wanted to
avoid having to install the hplip drivers on all workstations, we
thought we'd employ saned to make the scanner available on the
network.

This worked fine until we upgraded to Debian jessie / sane 1.0.24
(from 1.0.22).

Now, while I can access the scanner from the "scan server" just
fine:

  # scanimage -L
  device `hpaio:/net/HP_LaserJet_3052?ip=192.168.14.30' is a Hewlett-Packard HP_LaserJet_3052 all-in-one

saned does not know about it anymore:

Why is the libsane-hpaio.so backend not finding the scanner that
scanimage can access?

Thanks,
