USB authorization

[Daniel Kopeček]

Hello,
 I'm trying to find out whether FreeBSD has an equivalent to the USB
(de)authorization interface that is implemented the Linux kernel [1],
i.e. if there's a flag for each USB device and interface that controls
whether that particular device/interface is allowed to communicate
with the system.

So far I haven't found anything promising so I guess there's no such
interface. If that's true, do you think it would hard be to implement?
Would it require refactoring of the USB subsystem or just a few lines
at the right places and something to export this interface to the user
space?

Thanks!
