Seeing that you are using Perfection V600s I am pretty sure you are
using the epkowa backend.  If so, upgrading sane-backends will not help
at all.  You should upgrade to the latest iscan version, 2.30.1, which
contains USB 3 fixes.  I am not sure they will address your problem,

You can download the lastest collection of packages (iscan, iscan-data
and a non-free interpreter plugin for your model) from
