This patch (as1022b) adds stub methods for suspend and resume to the
usbfs driver. There isn't much they can do since there's no way to
inform a user task about the events. But it's important to have the
stubs, because an upcoming change to usbcore will automatically unbind
drivers that don't have those methods when a suspend occurs.
