[sane-devel] Is the Iscan backend "epkowa" also affected by USB3 issues?

Hello Olaf Meeuwissen,
we (i.e. openSUSE) got an issue report of a user
who uses the "epkowa" backend for an
Epson GT-X770 / Perfection V500
at a USB port with the xhci_hcd kernel driver module
which does not work, cf.
Now I wonder if the "epkowa" backend could be
also affected by the current sane-backends 1.0.25
"Workaround for USB3 problems in Linux kernel"
that seems to no longer work with newest kernels, cf.
In other words, I wonder if the "epkowa" backend uses
the sane-backends USB code or if the "epkowa" backend
implements USB communication on its own.
In the end I like to understand if a version change
of the installed sane-backends software on the user's
computer could make a difference whether or not the
"epkowa" backend works with the xhci_hcd kernel module.
