Bug in plustek_pp backend

Hi together,

upgrading from my former 32bit-system to a 64bit one I
noticed a strange 
behaviour of my Plustek OpticPro 600P: It is recognized
without any problem 
by scanimage -L. But when I try to scan it waits its 30
seconds until the 
lamp is heated up, then I can hear the motor bringing the
lamp in starting 
position and directly afterwards the lamp is switched off.
Then a short 
break, again the motor doing something, short break again
and then the 
(switched off) lamp begins its travel over the scanning
area. When it hits 
the end of the scanner it doesn't stop but still likes to
continue what I 
always stopped by pulling the plug or hitting CTRL+C. With
the same 
backend-version but in a 32bit chroot-environment the
scanner works smoothly. 
When the lamp returns to its starting point it travels
relatively silent in 
32bit. In 64bit it's a noisy sound.

Some information about the system I'm using:
Kubuntu on AMD64 3500+, all parport options (EPP, SPP etc.)
tested in the 
meantime with no difference. 
libsane version 1.0.17-1ubuntu4
I also tested the newer backends including the daily
CVS-snapshots with always 
the same result.
I always used the direct access to the scanner, no kernel
module.

Best greetings and keep up the good work that enables me to
still use my 10 
years old scanner! 
Martin

Hi,

please upgrade to a more recent version, at least in the CVS
snapshots
this has been fixed.
