I neither not have this one nor a similar model
so that I cannot help with model-specific issues.

In general regarding "Trouble-Shooting (Debugging)" see

> OpenSuse 13.1

openSUSE 13.1 provides sane-backends-1.0.23 where
this model in not listed as supported.

Strange - according to
the "CanoScan 9000F Mark II" is listed as supported
by the pixma backend versions 0.17.23 and 0.17.24
but 0.17.25 is not (yet?) listed there.

In my current sane-backends-1.0.25 "man sane-pixma"
shows that the "CanoScan 9000F Mark II" works with
this backend.

I assume you have sane-backends-1.0.25 installed.

And what does it show when you configure it?

What are the URLs of those "2 cases in Forums"
so that we could understand what you are talking about?

Only a guess:

Is your scanner connected to a USB 3 port at the computer?

If yes, this does not work, see

You need a newer kernel for USB 3 where the xhci USB driver is
somewhat fixed. But you need additionally sane-backends-1.0.25
that has some additional workarounds for the broken xhci driver.

If possible connect the scanner to a true USB 2 port
this is a USB port where "lsusb -t" does not list
that the kernel-"Driver=xhci" is used for it, cf.
For the fun of it:
My machine has 4 USB ports, two labeled with
the "super speed" USB logo (a.k.a. USB 3) and
two labeled with the normal USB logo (a.k.a. USB 2)
but for all 4 ports xhci is used and it fails on all 4 ports.
