It looks like bootpc_init() is getting called before USB has found the
ethernet adapter.  It might be fixable with a simple patch such as the
following, but I really don't know whether this will work, and even if
it does, whether it's a good idea (hopefully someone more knowledgable
will offer an opinion).  But if nothing else it's an interesting
experiment to try.
