Re: use of an intermediate device to handle USB interfaces

I recently did an install on a fairly vanilla server system.  I counted
nine PCI busses in the autoconf output - and at least one bridge for
each one.  The machine had only one physical PCI bus (connectors &c) as
far as I could tell.

Given that sort of noise, I think a ucommon shim in a few USB
attachments is totally ignorable.

(I'm not commenting on the rest of it because I don't know enough about
USB to say anything intelligent.  For exmaple, I'm not clear on the
difference between a device and an interface.)
