The scanimage threshold option worked in the 1.0.9 backend with my Epson 1660 Photo Perfection scanner. After uninstalling the 1.0.9 backend and installing the 1.0.12 backend, scanimage complains "attempted to set inactive option threshold" and fails. I took a quick look at the epson code (which I am not familiar with yet), but have not found anything yet. Was this change intentional?
Thank you for your help, Peter
