See "Trouble-Shooting (Debugging)" at
https://en.opensuse.org/SDB:Configuring_Scanners

FYI:
Nowadays "xhci_hcd" kernel driver/module issues (a.k.a. "USB 3")
are the most often cause of "Error during device I/O", cf.
http://lists.alioth.debian.org/pipermail/sane-devel/2016-November/034901.html
and follow the links therein.
