[sane-devel] Epson V600 Perfection Scanner

[Monosij Dutta-Roy]

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.
