Actually, I'm arguing that you (FreeBSD, not necessarily the USB layer) need
to better support the *main-stream* devices better (I care much less about
the outliers, because by definition, the quality of their support affects
far fewer people). These Toshiba drives are vanilla stuff, used by many for
backups

I do understand, but in some ways I don't. FreeBSD is a great system,
superior to Linux in many ways that have been discussed ad nauseum, but USB
devices, particularly disks and flash-based devices, are ubiquitous these
days, and FreeBSD's support for these devices is weak, weaker than Linux and
even OpenBSD (in my experience). This seems like a very odd place for a
gaping hole in the system, particularly after all the work you did to
re-implement the USB layer.
