[sane-devel] scanbd and Canon LiDE 60: buttons not recognized ?

Sat, 15 Apr 2017 03:15:25 -0700 

Hi,
my LiDE60 is working well, either directly using scanimage with scanbd not running, as "genesys:libusb:001:016" or with running scanbd using xinetd as "net:localhost:genesys:libusb:001:016". 
However, none of the four buttons seem to be recognized:

        # Examples:

        # scriptdir = /some/path

# It can be necessary to load firmware into the device when it is first # inserted. For example, scanbuttond backend does not know how to load # scanner firmware, and it can be rectified by making a custom script. 
        # A simple command like "scanimage -L" in an example insert.script
        # invokes saned and it loads the appropriate firmware if necessary.
# These scripts receive environmental variables named in the "environment" subsection: # SCANBD_DEVICE - device name (fixed string "dbus device" for dbus notification) 
        # SCANBD_ACTION - "insert" or "remove", so one script can be used.

include(scanner.d/hp.conf)
include(scanner.d/pixma.conf)
include(scanner.d/snapscan.conf)
include(scanner.d/canon.conf)
#include(scanner.d/plustek.conf)
I also commented out the include statements for the devices, tested different sections for the options such as "preview", tried the default Ubuntu-Package for 16.04 as well as the newest version 1.5.0 of scanbd.
Syslog contains essentially the same output as scanbd -f -d7, no events registered at all on button press. Scanimage -A also gave no evidence for the presence of scanner buttons.
For me it seems that the problem might be the scanner button options not being recognized, strangely there are options "with no name" ?! 

Thanks very much for any hint !

  Florian
