Detailed Description

This represents a bus on the system. By default, this bus instance will scan for changes every 5 seconds. If this bus only has to be updated after a notification sent by the system, set m_bNeedsPolling to false in the constructor, and implement the OnDeviceAdded(), OnDeviceChanged() and OnDeviceRemoved() methods.

The PerformDeviceScan() method has to be implemented by each specific bus implementation.
