I am writing a KMDF filter driver on windows 8 which should disable/enable a USB device based on laptop lid close/open respectively, and this should be done when the ‘Lid Close Action’ settings in ‘Power Options’ is selected to ‘Do Nothing’.
1.i am clear on how to get the notification of lid open/close.
2. but i am not able to get any information about the notification that my driver can receive when the ‘Lid Close Action’ settings are changed… is there any way that i can register a callback for this settings change, so that my driver can be notified when the settings gets changed ??
This is not a scenario we want to encourage. Rather, your device should go idle when it is not used by the user. Please email me off the list and we can flesh out your scenario more fully
