[sane-devel] Scanmaker 4800...xsane sees it but freezes

[Richard C. Rath]

Hi, 

I am trying to get an ols microtek scanmaker 4800 running on debian
using xsane.  Xsane loads fine, seems to see the scanner correctly, but
when I hit preview or scan, it freezes and I have to force a quit.  

I tried commenting out all the other scanners in the conf file, but that
had no effect.

I ran gdb, as suggested in the help file, but have not a clue what the
output means.  I have pasted it in below.  Any ideas how I might get the
scanner running?  It used to run fine on windows xp, so I know the
hardware works.  I got a new computer at work which downgraded to vista,
so the scanner no longer works on the pc, so I am trying to get it going
on my old debian laptop.

Here is the gdb output:
