I still don't agree with this. The bus name should be passed
explicitly by the user of the API.

NAK.

Please explain why you think the bus name should be explicit.
If the bus is ambiguous, it can be explicited by the user.

I see some good benefits in being tolerant with the bus/device
representation. It provides a smooth transition to the bus model.
