I last used it without any problem 180626. Since then, I've updated my kernel & some other pkgs. I've checked the USB physical connection ; the scanner 'ready' light is on. I've remerged 'xsane' & 'sane-backends' & rebooted. Following my notes, I've done : root:500 ~> sane-find-scanner ... found USB scanner (vendor=0x04b8 [EPSON], product=0x013b [EPSON Scanner]) at libusb:001:004 # Your USB scanner was (probably) detected. # It may or may not be supported by SANE. # Try scanimage -L and read the backend's manpage. root:501 ~> scanimage -L device `epkowa:interpreter:001:004' is a Epson Perfection V550 Photo flatbed scanner The first time I ran these commands (I don't remember which), the scanner itself made the noises it usually does when starting. This model needs a driver which is not included in 'sane-backends' & which I downloaded from Nvidia & installed when I got the scanner 2017. The 'epkowa' driver is installed : root:505 ~> locate epkowa /etc/sane.d/epkowa.conf /usr/lib64/sane/libsane-epkowa.la /usr/lib64/sane/libsane-epkowa.so.1 /usr/lib64/sane/libsane-epkowa.so.1.0.15 /usr/lib64/sane/archive/libsane-epkowa.la /usr/lib64/sane/archive/libsane-epkowa.so.1 /usr/lib64/sane/archive/libsane-epkowa.so.1.0.15 My user is a member of the 'scanner' group : scanner:x:104:purslow I am puzzled : does anyone have a suggestion what to do next ? -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
