thx, but no change ... So now it's just the build system that is messing with me.
It was compiled with $ ./configure BACKENDS="pixma" --without-snmp --disable-ipv6 <cut> -> Network parameters: Build saned: yes IPv6 support: no Avahi support: no SNMP support: no CUPS support: no -> The following backends will be built: pixma $ make && sudo make install i added a few more exports on UMAX and LEXMARK and is now getting this trace: $ scanimage -h -v -v -v | ts <cut> [umax] sanei_config_attach_matching_devices(scsi Nikon AX-110) <cut> [pixma] pixma is compiled with pthread support. <cut> [bjnp] sanei_bjnp_find_devices: <cut> [lexmark] SANE Lexmark backend version 1.0.32-devel <cut> So LEXMARK and UMAX is still active !?!?!? The only active lines in /etc/sane.d/dll.conf is: net pixma $ sudo ldconfig -v | grep libsane libsane.so.1 -> libsane.so.1.0.25 libsane.so.1 -> libsane.so.1.0.23 What is cheating me, here? I AM able to insert debug printf lines in the frontend (scanimage) and pixma backend, and see them printed out, so I AM running my own compiled code. /Troels 2014-08-21 20:47 GMT+02:00 m. allan noah <kitno...@gmail.com>: > Troels- comment out all the backends you don't use in /etc/sane.d/dll.conf > > allan > > On Thu, Aug 21, 2014 at 2:40 PM, Troels Thomsen > <troels.pil.thom...@gmail.com> wrote: > > > > > > Hi , > > > > Adding > > 192.168.1.50 mf8230 > > to > > /etc/hosts > > was really effective! > > > > > > I still have a delay, now around 10 seconds. > > As seen below, its not the pixma enumeration that takes all this time > (only > > one second), so I'm suspecting it's because all the backends are given a > > chance to find a device.
