Well, in any case it is clear that drivers running in kernel space are not 
restricted to a certain API, say a USB manager API. So the *BSD drivers can 
potentially use all kinds of *BSD kernel calls, which makes the "let's 
write a compatiblity layer for USB *BSD drivers" quite difficult to be of 
any success in the real world.
