Hi Ilia and Jared I'm just registered to this ML to propose my patch to this back end driver made in the past weekend. And I see someone have my same problem :) I've used hp5590 scanner with scanbuttond for years. Some week ago I've upgraded my system to debian 9 and discovered that scanbd does not works anymore with my scanner. I really need this functionality so I've made modifications to hp5590.c code to export the options . Is a first attempt and the backend called by scanbd threads makes buttons quite responsive without using a self polling thread. I've made a patch file for debian 9 stable version package (yes but the real patch is for hp5590.c only) If you are interested I can send it (or tell me if I have to release into the repo directly I'm new user here :))
