Hi, Daniel.  I've occasionally seen this problem, where the process hangs
and can't be killed, and ieee12844pp can't be unloaded, but I haven't been
able to reproduce it reliably to try to track it down.  What sequence of
steps do you take to cause the problem (i.e. resolution and geometry
settings, preview versus non-preview scans, number and frequency of scans,
etc.)?

I've found trial and error to be the most reliable way to determine which
OIDs are supported by which models.  According to my testing very few are
supported by the 1150, 117x, R series, and PSC500.  That's why I put an "X"
for xojpanel and these models on http://hpoj.sourceforge.net/suplist.shtml.

Try looking around in the SANE mailing list archives
(http://www.mostang.com/sane).  I think there has been some discussion about
this problem there in the past, but I don't remember the solution.  Was gimp
installed when you configured and built SANE?  Was SANE's configure script
able to find GIMP?

Alternatively, you could try xsane, which is linked from there.  xscanimage
isn't really being maintained anymore.
