Hello Olaf,

The epkowa backend uses its own *copy* of the sanei_usb code.
There was a minor fix for USB 3.0 connected scanners in 2.30.1
(dated 2014-12-03).
That same fix was applied to sane-backends on 2014-12-10.
Please note that iscan does *not* actively track changes to the
sane-backends version of the sanei_usb code. Also, iscan-2.30.1
is the most recent version.
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.
That is rather unlikely but not impossible as it may depend on what
other backends do during their sane_init() and sane_get_devices().
If all other backends are disabled, changing the version of the
installed sane-backends should not make a difference. That is
because the dll backend doesn't do anything USB related itself.
Hope this helps,
Many thanks for your explanation.
It helps a lot!
Kind Regards
Johannes Meixner
