>From  HoneyComb that was delivered in 2021-June (same report as I made on
SolidRuns's discord area, then some extra notes):

I've never had problems with USB3 devices that I've tried ending up without
SUPER (5.0Gbps) status. (But it is only a few types of devices.) The Realtek
USB
10/100/1000 LAN is plugged into the port nearest to the board.

I've been running various FreeBSD versions over the time. I use bectl to bo=
ot
any of releng/13.0.0 , stable/13, and main [so: 14], mostly 13.0R and main.
For example (root-is-ZFS):

# uname -apKU
FreeBSD CA72_16Gp_ZFS 14.0-CURRENT FreeBSD 14.0-CURRENT #12
main-n249019-0637070b5bca-dirty: Tue Aug 31 02:24:20 PDT 2021=20=20=20=20
root@CA72_16Gp_ZFS:/usr/obj/BUILDs/main-CA72-nodbg-clang/usr/main-src/arm64=
.aarch64/sys/GENERIC-NODBG-CA72
 arm64 aarch64 1400032 1400032

I usually boot an Optane in the PCIe slot but also boot an external USB3 SSD
that
has a slightly modified copy of the Optane (recopied & adjusted as I progre=
ss).
The system is built with -mcpu=3Dcortex-a72 (mentioned because it is unusua=
l).
The USB3 ssd can boot RPi4B's with 8 GiBytes of RAM. (I avoid ZFS when ther=
e is
less than 8 GiBytes.) None of those systems have had problems identifying U=
SB3
SUPER as appropriate. I've used the Realtek USB3 LAN type of dongle on all =
of
them.
