I have the same scanner and much of the same problems as Nicolai, only
more...
I started out with a 2 1/2 years old PIII/500MHz system with an USB
controller that identified itself as Intel something, rev. 1.
Yesterday I upgraded the box to an ASUS motherboard with AMD 1800XP
and the nVidia nForce 220-D chipset, which has an USB controller that
allegedly is standard OHCI. I've also tried kernels 2.4.18,
2.4.19-pre8 and 2.5.16 (all uhci modules with the old motherboard).
Nothing has made any difference as far as I can see.
What is strange is that scanimage from SANE (the command-line tool)
works reasonably well, it crashes if I use some of its parameters and
I cannot seem to get the colors right, but otherwise it seems to scan
without any problems. However, Vuescan manages previews, but crashes
within a second when I hit the scan button, and xscanimage (SANE)
crashes after drawing a couple of lines of preview. I don't know
enough about kernel hacking to speculate much as to the reasons for
this.
I'll be happy to test patches. I might also try to look into this
myself, but it's a few years since I last looked hard at C code, so I
won't promise that that leads to anything.
