Any traces what could be the reason?
With 4.7 (i386) and my patches it works now ..kind of..
And modifying /usr/local/etc/sane.d/plustek.conf as follows:
[usb] -> [usb] 0x04B8 0x010F
device /dev/usbscanner -> device /dev/uscanner0
But it should not be neccessary.. USB.. Plug & PRAY! :)
xscanimage works ok.
scanimage works (stepper motor goes beyond physical limit in this case).
xsane crashes after scan, but won't hang anything.
One real nasty thing I discovered is that if one cancels a scan it can happen
that the step motor continues to drive the scanner wagon beyond physical limit
*until* you cancel it by requesting a new scan or disconnect power.
Something that ought to be fixed..

There is also a speed issue:
Windoze FreeBSD
Preview 26 sec 50 sec
300 dpi, 24 bpp, A4 45 sec 66 sec
Windoze system:
Toshiba laptop, CPU-Intel Celeron 650, 64 MB Ram, Windoze Me
FreeBSD system:
Motherboard A7V333, CPU-AMD XP1800, 256 MB Ram, FreeBSD 4.7
One can clearly hear (audiowise) that the freebsd system does the scanning in
chunks while windoze does most tasks in one "sweep".
