Hence USB has its own directory system which is not part of devfs, it was natural to also have a separate utility to set the permissions and ownership, which might become more complicated than simply a user and group. At EuroBSDcon this year I got some ideas about defining functional permission groups, like permissions for all USB keyboards for example, instead of permissions for individual devices. This pradigm will then break with chmod and chown. --HPS
