Disabling selective suspend for USB devices
My USB mouse (Microsoft WheelMouse Optical 1.1A) enters a low power idle state after a few seconds despite me having disabled USB selective suspend from the power plan settings and setting EnableSelectiveSuspend to 0 in the registry of the root hub device parameters.
I have already gone through input.inf, msmouse.inf and usbport.inf in the DriverStore's FileRepository to look for potential driver-sided suspend or idle settings, but only found AddReg values concerning the EnableSelectiveSuspend key and changing those to disabled didn't help. I could not locate HcDisableSelectiveSuspend, DeviceIdleEnabled, DefaultIdleState, UserSetDeviceIdleEnabled in the infs.
I suspect the mouse internally is set to enter idle and request the bus to power down accordingly.
Is there any way to forcefully disable suspending of the mouse? Is taking USB power policy ownership necessary to overrule the device's specifications?
Thanks!
