Seems that the CanoScan LiDe 90 is one of the scanners built by
Canon that are not supported well. That's a reason to avoid them. :-)
I had similar issues with a LiDE 45 (I think it was), and I did
soon replace it with a SCSI scanner that worked out of the box

Mayve the SANE team will get this scanner to work later on. But
at this point in time, the scanner will be outdated. :-)

This indicates that this scanner works differently than those
usually supported by the genesys backend. I "love" Canon for
making things complicated exactly this way.
Maybe this scanner is compatible to another driver, but that's
only a guess. Maybe it's not compatible to anything that exists.
