Comment # 5 on bug 976813 from Johannes Meixner

Yes - lower level stuff always changes.

It is one problem of proprietary third-party drivers
that they are not adapted to changes in lower level stuff
and then third-party software may suddenly fail.

I wonder how you come to the conclusion that it is
we (i.e. openSUSE) who made some bugs somewhere
because usually we do not make the software but
we primarily distribute free software as is.

What is the full output of
  lsusb
and
  lsusb -t
on your computer where the scanner is connected?
