This brings USB bus more in line with how newbus is supposed to be used. Also, because of the two-pass probing the following message was produced by devd in default configuration when almost any USB device was connected: Unknown USB device: vendor <> product <> bus <> This should be fixed now. Note that many USB device drivers pass some information from probe method to attach method via ivars. For this to continue working we rely on the fact that the subr_bus code calls probe method of a winning driver again before calling its attach method in the case where multiple drivers claim to support a device. This is done because device description is set in successful probe methods and we want to get a correct device description from a winning driver. So now this logic is re-used for setting ivars too.
