Good morning, Michael!

It's time to try to find the root of the problem. First we could do is
to enable backend debug information and try to scan.
You could do that by setting the variable SANE_DEBUG_HP5590 to 50 then
starting your frontend. In case of network scanning,
that should be done on the server side, when starting 'saned' daemon.

Just a few examples:
- local scanning
SANE_DEBUG_SANEI_USB=50 SANE_DEBUG_HP5590=50 <you frontend> 2>hp5590.log

- network scanning
SANE_DEBUG_SANEI_USB=50 SANE_DEBUG_HP5590=50 saned -d 2>hp5590.log

In either case, the backend will emit debug messages which are
redirected to the file hp5590.log. The USB debug messages will be
shown as well. You can send the file to me (CC'ing sane-devel),
perhaps something will show up.

Perhaps it's worth to try local scanning first to exclude the
possibility of network related problems.
