Hi, Paul! No worries - this is the right place.

Frankly, didn't test the backend under FreeBSD, hope no dramatical
differences would arise.

Could you please provide debug output when scanner works well (setting
SANE_DEBUG_HP5590 variable)?

Well, at least the device accepted the sequence of commands. I suspect
that something is wrong with setting scan area, although didn't face
similar issues.

I suppose this output was produced after the "Invalid argument" error
appeared. Could you please do the same but in a fresh condition (eg.
after the device will be initialized by unpligging the power cord then
re-plugging it)?
