Solved per pkg-readme of course :-)

USB
===
Since USB scanning will be handled by libusb, you need to allow
the user access to the corresponding USB endpoint. To do so, find
where your scanner is attached to using:
$ usbdevs -v
then change the ownerships accordingly.
e.g.
Controller /dev/usb0:
<...>
addr 05: 03f0:4812 HP, Officejet 7500 E910
high speed, self powered, config 1, rev 1.00, iSerialNumber
MY2793100Q05JB
driver: umass0
driver: ugen1
# chown <username> /dev/ugen1.* /dev/usb0
To preserve your changes after a system update, use rc.local(8).
Alternatively, hotplugd(8) attach/detach scripts can automate this.
You can grant multiple users direct access to the scanner by adding them
to the
_saned group and allowing access to its ugen(4) device.
e.g. chgrp _saned /dev/ugen1.* && chmod 660 /dev/ugen1.*
