Hi, I try to use a Nikon Coolscan 5 ED using Debian 9.3 AKA Stretch.
Scanner ought to be supported with the coolscan3 backend. "scanimage -L" needs very long to list the scanner. "scanimage -T" reports "Error during device I/O" Scanner "disappears" after one "scanimage -L" or any other request to do anything else meaning it is not displayed by doing "scanimage -L" another time. Full session as root (to make sore it's not a matter of permissions) root@radioactive:~# sane-find-scanner -q found USB scanner (vendor=0x04b0 [Nikon], product=0x4001 [LS-50 ED]) at libusb:001:027 root@radioactive:~# sane-find-scanner -L unknown option: -L, try -h for help root@radioactive:~# scanimage -L device `coolscan3:usb:libusb:001:027' is a Nikon LS-50 ED film scanner root@radioactive:~# scanimage -T scanimage: no SANE devices found [power cycling the scanner] root@radioactive:~# scanimage -T scanimage: open of device coolscan3:usb:libusb:001:028 failed: Error during device I/O root@radioactive:~# Any ideas what could be wrong? Any information you might need in addition? Thank you very much! Sebastian
