RE: Any Rules for Behavior of bus numbers changing?

Thanks for  all the responses, both public and private.

Looks like there is currently no way to enforce this 
behavior.  Hopefully future IO specifications will
address this issue.

Regards to all,

Subject:	Any Rules for Behavior of bus numbers changing?

We are seeing some cards Windows drivers not work because
their bus number has changed between boot cycles, for instance
when a card with a bridge on it is installed and enumerated before
the card in question. 

Is there anything in the spec about how a driver should be able
to respond when it's card gets located on a different bus than the
one it was on during it's installation?

thanks,
