Thanks Richard , it works for me with 11.10 64bit (brscan2)

I am closing the simple-scan task, because looking at the workaround/fix it is clear that this is not a problem with simple-scan but with libsane/sane-backends/the scanner driver and simple-scan cannot do anything (reasonable) about this.
