PnP and Power Management Scenarios in UMDF

Warning

UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2.

The archived UMDF 1 samples can be found in the Windows 11, version 22H2 - May 2022 Driver Samples Update.

For more info, see Getting Started with UMDF.

The following PnP and power management scenarios show the sequences in which the framework calls a UMDF driver's event callback functions:

• A User Plugs in a Device
• A User Unplugs a Device
• A Device Enters a Low-Power State
• A Device Returns to Its Working State
• The PnP Manager Redistributes System Resources
