<p><font size="-1">Hello,<br>
I am having an issue when trying to use a Avision AV210D2+ scanner.<br>
I am running CentOS 7.2 using sane-backends 1.0.24. <br>
</font></p>
<p><font size="-1">fujitsu fi-6130z and 7160 both work fine on the same platform.<br>
<br>
USB 3 is turned off in the bios and lsusb -t shows the scanner is using the ehci-pc usb module.
<br>
<br>
The scanner is seen properly by sane-find-scanner and scanimage -L. <br>
device `avision:libusb:002:032' is a Avision AV210D2+ sheetfed scanner<br>
<br>
When attempting to scan a documents, scanimage -d avision >test.jpg the console error message<br>
is segmentation fault. dmesg shows segfault at 7fa93c82a9d0 ip 00007fa94a2a1de0 sp 00007fff384ef888 error 4 in libpthread-2.17.so[7fa94a299000+17000]<br>
<br>
Some things I have tried:<br>
- passing various supported geometry and resolution options to scanimage .<br>
- removing all backends from dll.conf except for avision<br>
- rotated amongst all usb ports<br>
- bios update to workstation</font></p></blockquote></body></html>
