--- Comment #20 from Johannes Meixner ---
It is a known issue at SANE upstream that some/many/most? scanners
do not work at USB 3 ports on some/many/most? computers.
I am not at all a USB expert which means I can neither debug
lower-level USB issues nor fix them.
As far as I noticed on some USB3 related mail threads on
the "sane-devel@lists.alioth.debian.org" mailing list,
something seems to have changed how the kernel works
in case of USB3 compated to how it worked with USB2.
FYI, see also "USB Speed" at
https://en.opensuse.org/SDB:Configuring_Scanners
From my non-expert point of view the issue is not caused by openSUSE,
neither by openSUSE-specific changes of our kernel or libusb
nor by openSUSE-specific changes of the sane-backends software.
Therefore the issue belongs to "upstream", either the kernel
or libusb or SANE or perpaps even all of them.
You can still add comments to this issue report regardless that
it is closed as "upstream" - i.e. there is no need to reopen it
only to provide more information.
