Thanks for the files. That policy.out file doesn't look like it should,
at all. It's supposed to contain a pile of additional rules that look
like whatever the distribution's libsane package uses for USB devices.
It appears that the Debian package maintainer split off the USB devices
into a 20-sane.hwdb and only left the SCSI devices in 60-libsane.rules.
This was done to address Debian bug 869244 (see ).
Unfortunately, that seems to have broken the logic in make-policy-file.
That script has been working fine for more than a decade on multiple
distributions but it looks like it needs some fixing up now. The Debian
change will problably also affect *all* of Debian's downstreams :-/

Considering the above, I do not think xhci is involved. Even more so
seeing you're using a USB 2.0 port.
Hope this helps,
