I wonder why its not the default already.  Seems Novell didn't push
that change upstream in the last year either.  I'd suggest bringing
this up on the linux-usb-devel at lists.sf.net list.  Perhaps someone
responsible for the hid code will be able to give you an answer
as to why this change hasn't happened.
