: No, then you have to restore the libusb-0.1 library.

Yes.  We need a migration guide to usb2 that documents these sorts of
things for people, or we're going to get hammered with lots of
questions from people using ports that suddenly don't work...  The fix
may be easy, but people have to know about it.  Ideally, the ports
folks would be involved with a solution too...

Devices are what are failing.

: device does still not work?

I haven't.  But usually it is things like burning a DVD from a usb
disk doesn't work to a USB DVD player (using storage_ata).  Burning it
from a firewire disk does seem to work.  There's no I/O errors when
this happens.  The uscanner thing that maybe this will fix.  I've had
trouble unloading usb2 modules since sometimes they hang.  It can be
quite time consuming to file bug reports on all these things, since I
don't want to file one that wastes your time for being too vague or
unreproducible.  I've only recently started using usb2 heavily for
day-to-day tasks rather than just-test-it-out tasks I'd been doing
before.
