Abstract: A filter driver (usable with a system having a bus, a host connected to the bus and one or more devices connected to the bus) that supplants first device objects (DOs) with second DOs. Such a filter driver includes: an intercept code portion to intercept a set of data identifying one or more first DOs, respectively; a determination code portion to determine addresses of second DOs corresponding to the first DOs identified by the data set, respectively; and a change code portion to change the data set such that members thereof identify the second DOs rather than the first DOs.
