Inspection of the packet-usb code seems to indicate that under certain
circumstances, information describing a USB SETUP operation can be added to the
'USB URB' tree instead of the 'URB setup' tree. This may be a theoretical and
not a practical issue; the conditions required appear to be either an INTERRUPT
or ISOCHRONOUS URB in which the Device Setup Request is marked as 'relevant'.
It may not be possible for these conditions to occur, in which case the
erroneous code should just be removed.
