Are you sure that this is the name of your scanner? According to
google, such a scanner does not exist.

Checking if a scanner is supported before buying it is usually a good
idea. It doesn't help to know that 98% of HP scanners are supported if
your scanner is one of the 2%. In fact, if your scanner is actually a
"PSC 2355" it should work with the hpaio backend. At least it says "PSC
2300 series" on its web site.

Use sane-backends 1.0.17 or newer. hpaio must also be built with this
or a newer version to enable a work-around for this problem.
Another work-around is to do "rmmod usblp".

As the scanner is not supported by the hp backend this won't help.

So it's there.

Ah, really a PSC.

"hp.conf". This scanner is NOT supported by the hp backend but by
hpaio. So fiddling with the hp backend won't help.

The SANE website doesn't say this. In fact it points to the hpoj/hplip
pages for reference. These are external backends so it's usually better
to contact their authors directly.
