Hi Olaf - Thank you for your email. Answers for your questions as follows:
$ sudo SANE_DEBUG_DLL=1 SANE_DEBUG_EPKOWA=hex scanimage -L 2>&1 | tee log [sanei_debug] Setting debug level of dll to 1. [dll] sane_init: SANE dll backend version 1.0.13 from sane-backends 1.0.27 [dll] load: couldn't find backend `v4l' (No such file or directory) [dll] load: couldn't find backend `pint' (No such file or directory) [dll] load: couldn't find backend `epkowa' (No such file or directory) No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages). I have the epkowa.conf file installed. But no epkowa backend listed in dll.conf. As I stated in dll.conf epson and epson2 are uncommented. $ locate epkowa /etc/sane.d/epkowa.conf /usr/lib/sane/libsane-epkowa.la /usr/lib/sane/libsane-epkowa.so.1 /usr/lib/sane/libsane-epkowa.so.1.0.15 /usr/share/iscan-data/epkowa.desc /usr/share/man/man5/sane-epkowa.5.gz --------------------------------------------------- I have copied some of the contents of the epkowa.conf in case some aspects need to be uncommented? # Detect all devices supported by the backend. # If you don't have a SCSI device, you can comment out the "scsi" # keyword. Similarly for the other keywords. # usb scsi # For any USB scanner not known to the backend (yet), you may, at your # own peril(!!), force the backend to recognise and use it via libusb. # You can do so by the following configuration command: # # usb <USB vendor ID> <USB product ID> # # SEIKO EPSON's USB vendor ID is '0x04b8' (without quotes). In order # to find the USB product ID, use lsusb(1). # A sample configuration for the Epson Perfection 1650 (Epson GT-8200), # which has a product ID of 0x0110, would look as follows: # #usb 0x04b8 0x0110 # For SCSI devices not detected, you can add an entry like: # # scsi EPSON GT-20000 # # where the GT-20000 bit corresponds to the SCSI model information as # shown in the output of dmesg(1) or in the /var/log/kern.log file. ----------------------------------------------------------------------------------------------- Hope this is all the info you needed. Please let me know what I should try next. Thank you.
