Hi Ed,

Basically there is nothing wrong with using chmod and chown. 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.
