Broken USB 3.0 port on Pine Rock64 SBC

Goal: Turn a Rock64 SBC into a NFS server.
* {root} installed on microSD
* NFS share an external USB 3.0 drive.

Works on Linux - Armbian & DietPi

On FreeBSD, I tried:
13-RELEASE
14-CURRENT

In both cases (release/current), the single USB 3.0 port on the Rock64
doesn't appear to recognize any drive. The single 3.0 USB port appears
disabled. If I plug the external hard drive into either one of the two
USB 2 ports - the drive is recognized and shows in dmesg. If I plug
into the single USB 3 port, no messages displayed in dmesg. Kernel
doesn't recognize anything from UHCI / XHCI on the USB 3.0 port.

Hoping this is potentially a quick fix such as a tuneable in
/boot/loader.conf.

Drive works fine in either of the two USB 2.0 slots. When plugged into
the USB 3 slot, nothing happens. dmesg shows no activity as if I never
plugged it in.

dmesg | tail -10

^^^ plug it in, run dmesg again..... no change.

Then I plug it into either one of the two USB 2.0 ports, and it
works... dmesg shows:

ugen1.2: <Seagate Expansion Desk> at usbus1

Hardware is Rock64 single board computer. Device has one USB 3.0 port
and two USB 2.0. :seems: like the single USB 3.0 port is registered as
USB 1.0.
