[sane-devel] Avision AV210D2+ segfaulting

[Wolf Drechsel]

Hello,
just my 2cts:I'm suffering from a "avision" problem as well - we seem
to be quite a bit lost at the moment, as far as I understood, the
avision backend does not have a maintainer at the moment.
An ugly workaround for me is to scan from my laptop which is running
debian 8.6 now - I do not have any problems scanning with that machine.
Maybe you want to give a debian live system a try?
My guess (but I do not know anything about programming) is that in the
last few years USB timing was changed, so older kernels work better
than newer ones. I read that CentOS is using a comparatively old
kernel, but with quite a lot of patches - can those cause the harm?
cheers,Wolf
