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!

Hi,
We have some sysctls you can set which allow or disallow USB enumeration:
hw.usb.disable_enumeration: 0
dev.uhub.0.disable_enumeration: 0
We don't support wireless USB.
