Others have already commented on the fact the USB3 support and the xhci
kernel driver may be causing your trouble.

I have had XSane refuse to start on me when I switched devices in the
past. XSane keeps a cache with information on devices and settings in
the ~/.sane/xsane/ directory. Removing that directory may help.
However, when troubleshooting device detection issues, it is better to
use the scanimage command-line utility first. See the manual page for
usage details but
will give the list of detected, usable devices. You can select between
these with the -d option.
Hope this helps,
