Hello to everyone, Please, has anybody out there had any experience with the Epson-derived epkowa non-free backend for sane. I am trying to set up a scanner (Epson V100) on a remote headless machine in the lab coupled to an rsync script to transfer the scanned images to another machine with a GUI for processing.
I am getting permissions problems with libusb, so I have (1) added sane, iscan, epkowa rules to /etc/udev/rules.d, /lib/udev/rules.d (2) changed permissions (to 666, 777, and back to 644) of the device found by sane-find-scanner at /dev/bus/usb/002/003 (3) added the user to the scanner and saned groups (4) turned the scanner off and on, rebooted the computer (5) launching scanimage as root and as a normal user (6) issuing $SANE_DEBUG_SANEI_USB=255 scanimage -v -v -v> test.pnm 2> usb-verbose.log which gives the output ... [sanei_debug] Setting debug level of sanei_usb to 255. [sanei_usb] sanei_usb_init: initializing libusb-1.0 [sanei_usb] sanei_usb_scan_devices: marking existing devices [sanei_usb] libusb_scan_devices: Looking for libusb-1.0 devices [sanei_usb] libusb_scan_devices: found libusb-1.0 device (0x04b8/0x012d) interface 0 at libusb:002:003 [sanei_usb] store_device: add dn 0 with libusb:002:003 ... but none of this works: I am still getting those permissions issues $ scanimage -p > test.pnm scanimage: open of device epkowa:usb:002:003 failed: Access to resource has been denied Am I putting these rules in the right places and/or what permissions should i assign (i thought 777 would do it...!)? The machine is running ascii upgraded from jessie last week on a 4.9.61-gnu linux-libre kernel. There were no reports of the epson software trying to install any headers during installation. However, I am not sure if the iscan software only works through a GUI. Any pointers would be greatly appreciated.
