The instance ID can describe either a bus-relative location (for example, the game patch pes 2012 for pc USB port) or a globally unique descriptor (for example, a serial number).
Instead, they wait for the PnP manager to send a start-device command for the device to their Plug and Play dispatch routine.

Figure 8-37 shows an example of a simplified device tree.
For example, when the PnP manager is guiding device enumeration during the system boot (described in detail later in this chapter it asks bus drivers for a description of the devices that they find on their respective buses.
When a bus driver performs device enumeration, it reports device identifiers for the devices it detects back to the PnP manager.
Plug and Play support requires cooperation at the hardware, device driver, and operating system levels.38 Unknown device 102 Add legacy hardware 103 Uninstall 104 Sc an for hardware changes 107 P roperties 111 Enable 112 Disable 113 U pdate Driver Software.If a suitable driver isnt installed, the kernel-mode PnP manager communicates with the user-mode PnP manager to install the device, possibly requesting the users assistance in locating a suitable set of drivers.Thank you Shakil Hello, Using setupapi can I get hard disk serial info or smbios info?SetupDiDeleteDevRegKey Deletes the specified user-accessible registry key(s) associated with a device information element.Device Enumeration The PnP manager begins device enumeration with a virtual bus driver called Root, which represents the entire computer system and acts as the bus driver for nonPlug and Play drivers and for the HAL.
