Your research is correct so far.

It should not matter when the disk is attached; bsdinstall
will operate on any disk recognized by the system, no matter
if detected at program runtime or system boot.

The disk is not _recognized_. Only a file system can be
mounted (which requires the disk to be recognized). For
a USB disk, from the /dev/ugenX.Y device a /dev/daX device
will be "generated", corresponding to the disk. The process
you've shown above does not even reach that step.
If you go to the shell, you can enter "dmesg" to see the
last messages that will be the same. You can also check
the content of /dev regarding daX devices ("ls /dev/da*")
or use "camcontrol devlist" to check if they are present.

Yes, this looks like a typical "cannot connect" error.
Normally, a USB 3 disk would "switch down" to USB 2.
But USB 3 has a different current requirement, so it
could be possible that the power drain from the USB port
is insufficient for the disk to work properly. Can you
try to attach a separate power supply to the disk?
For USB 3, _all_ involved parts (disk, cable, ports,
controller, OS) need to be in "USB 3 mode", else it
probably won't work.
