- Support all resource descriptors. - Optimize card identification. - Detect cards that is no longer present on the bus. - Deactivate cards after the identification phase; they will be activated by start device IRP. - Provide a device description and compatible IDs to the device manager. - Prevent duplicate IDs across multiple logical devices. - Suppress warning about the usage of literals in port addresses.
