I can only guess here... First, sane-find-scanner finds everything that could look like a scanner, but it does not use the SANE libs so it's output does not help much. Now, it seems to show two scanners, do you have two? Does "scanimage -L" show anything, possibly running it as root? Many HP devices are supported via their HPLIP stuff, which is shipped by your distribution, but it's not directly a SANE problem if the HP stuff is used. Maybe you can check how it was working before. Simon
