Hello Sascha,

I'm delighted that you have a MX710 series, which we can now debug!

Could you read "man sane-pixma" and use the debug variable to get more
output? You'll need to run from the command line:

export SANE_DEBUG_PIXMA 3
xsane (or scanimage)

If there is a bug in the initialization, then maybe we will need
Windows USB sniff results also, but as a first step, we should be able
to see if something is clearly wrong or not.
