Should I disable the USB Selective Suspend setting?
As described earlier in this article, the Selective Suspend setting allows Windows to suspend the idle USB device for a specific amount of time by reducing the power to the USB port to which that device is connected. It does not affect other USB ports.
Generally, this is not recommended because after disabling this setting, all USB ports start consuming an equal amount of power, leading to rapid battery drain. But sometimes the Selective Suspend setting causes errors. In such a case, you can disable it.
