Previous testing, as in, before I finally set up the machine.  After setting it
up, I tried attaching a variety of other USB disks that may have all supported
a later protocol level.

However, in one of my previous attempts
(http://fuz.su/~fuz/files/volterra-dmesg-7.log), you can clearly see that the
boot disk is attached via the integrated USB 3.2 hub (however, it was a USB A

The 1969 date is because FreeBSD does not detect an RTC clock.  I'm not sure if
the machine has one; there's no battery inside, so how would it keep the date? 
See dmesg log:

Warning: no time-of-day clock registered, system time will not be set
