Yes, I go through these steps too and am also aware of the caveat(s). And it
sucks (see Subject), that one has to keep all of this in mind in order to

If we want people to give FreeBSD a try in good faith, it is both profoundly
stupid and dishonest on our part to claim, we have a working USB-system... It
does not matter, how great our buffer-sharing VM is, if a home user can't
process their photos with a FreeBSD-powered computer.
