- Partially implement IoAssignResources so that it creates a non-conflicting resource list from the requirements but it doesn't claim the resources for the device in the registry
- Partially implement IoReportResourceUsage so that it checks the resource list for conflicts but doesn't claim the resources in the registry
- Please test this revision with a variety of hardware and drivers because it activates several code paths in the PnP manager
- If this causes problems, look for "Denying an attempt to claim resources currently in use by another device!" in the debug log and report the bug to me
