My understanding is that USB will need to be done first since
the NIC is on the other side of USB.

https://wiki.freebsd.org/FreeBSD/arm/Raspberry%20Pi

makes it look like both USB and the NIC could come up easy.
And there is the potential to leverage more code.

+1 I just don't know what that is either. :)

Yes. The first step of this one could be to get the Graphics Toolkit into
the RSB.

Then leave USB UI devices as bonus work.

Based on history, I expect that putting it as bonus work and after
those tasks means it will be unlikely to be worked on anyway.
