[Hplip-help] xsane can't find photosmart 2575

[Robert & N. <act...@gm...>]

xsane 0.991 says no devices found. I checked
/etc/sane.d/dll.conf to make sure that hpaio was not commented out.
There was no hapaio so I added it.
Then I tried:
$ export SANE_DEBUG_DLL=3D128
$ scanimage -L

This was my output:
[sanei_debug] Setting debug level of dll to 128.

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).

sane-find-scanner gives me this:

What should I try next?
