I have a laptop that for some reason when i close the lid the usb shut off and i believe this is due to the usb power settings in the device manager say that the system can turn them off to save power. So when i close the lid the usb shut off. But if i change that setting and tell it not to turn off to save power they work fine.
I am setting this setting on the USB Root Hubs but when i reboot they revert back to being checked off to save power. Any ideas why this may be reverting back to the original state?
