[OpenIndiana-discuss] help with debug sane/hpaio needed

[Stephan Althaus]

Hello!

I need help debugging what's exactly going wrong when trying a scan..

------------------------------------------------------------

Background

------------------------------------------------------------

The package printer/hplip provides the sane-backend "hpaio"
after creating the empty directory /tec/sane.d/dll.d/
i was able to detect the USB Multifunction device

scanimage -L
device `hpaio:/usb/Deskjet_2050_J510_series?serial=CN1771H0JT05QV' is a
Hewlett-Packard Deskjet_2050_J510_series all-in-one

When i start a scan, the device is succesfully queried:

Any hints how to get to the root cause are welcome :-)
