Turns out the boot media being on the Thunderbolt Hub
is not important: being on a Del P. 5490 USB4 port
and the 2 Titan Ridge media already being on the
Thunderbolt Hub for booting, still leads to all 3
media showing up.

Apparently being present during the UEFI/ACPI early
activity leads to sufficient configuration for the
Titan Ridge media to be later found by FreeBSD.

Having only the boot media plugged in to the Hub at boot
and later plugging in the 2 Titan Ridge based media to the
Thunderbolt Hub resulted in the 2 xhci* showing up but the
media not showing up:

This is unlike the early hub-based Titan Ridge context that
I reported as far as the xhci* go, where the Hub was plugged
in after booting.

As might be guessed from all the above, if one of the Titan
Ridge based media is plugged into a Dell P. 5490 USB4 port
before booting (with the boot media on the hub), the Titan
Ridge media shows up after booting, just like when it was
on the hub.

The early UEFI/ACPI activity's USB4 configuration for its
own activities looks to be left in place and put to use by
FreeBSD's boot processing. Plugging in to ports only after
booting show what FreeBSD actually handles on its own. For
example, not finding the Hub's xhci*'s when the Hub is
plugged in after booting.

So, pre-connecting media before booting and leaving the media
connected can be appropriate as-is.


Note: I only have access to the 1 USB4 media that does not
involve Thunderbolt 3 --and I use it as the amd64 FreeBSD OS
boot media. (The other 2 media's contents are not even for
amd64 FreeBSD booting.)
