[sane-devel] Avision AV210D2+ segfaulting

[skerr]

Hi Wolf,

Thanks for your response.

I will be stuck using CentOS7. It uses a 3.10 kernel. But your correct, CentOS/RHEL, backport many patches/bugfixes/updates.

Its the platform we use for a very heavily modified Kickstart server installation we provide to our end users. I have the scanner working on my CentOS 5 and 6 kickstarts,  but we have hundreds out in the field and will have to update to 7 in the not too distant future. It wont be a complete show stopper as long as I can get scanimage to scan over the network to an avision hanging off a windows workstation.

Also , by you comments, I presume the maintainer listed in the avision conf file is no longer active. That was going to be my next recourse if noone on this list had any fruitful suggestions.

Hopefully I can come up with a solution before CentOS7 goes live.

Thanks,

Steve

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

Hello,
I am having an issue when trying to use a Avision AV210D2+ scanner.
I am running CentOS 7.2 using sane-backends 1.0.24.

fujitsu fi-6130z and 7160 both work fine on the same platform.

USB 3 is turned off in the bios and lsusb -t shows the scanner is using the ehci-pc usb module.

The scanner is seen properly by sane-find-scanner  and scanimage -L.
device `avision:libusb:002:032' is a Avision AV210D2+ sheetfed scanner

When attempting to scan a documents, scanimage -d avision >test.jpg the console error message
is segmentation fault. dmesg shows  segfault at 7fa93c82a9d0 ip 00007fa94a2a1de0 sp  00007fff384ef888 error 4 in libpthread-2.17.so[7fa94a299000+17000]

Some things I have tried:
- passing various supported geometry and resolution options to scanimage .
- removing all backends from dll.conf except for avision
- rotated amongst all usb ports
- bios update to workstation
