Try this Device Manager > Human interface devices > USB Input device. In this I disabled the option 'Allow the computer to turn off this device to save power' in the power management tab. Also disabled 'Selective USB suspend' in power settings.
If still same try this Turn off computer Unplug cord Remove the battery and hold down power button for 30 seconds and then put it back and try computer.
