What is USB Selective Suspend and How To Enable or Disable it

First, let us try to understand what is Selective Suspend Feature in USBs. We all know that , when a system is inactive or idle for some time, it automatically goes on a low-power state(Sleep , Hibernation, etc.) to conserve the power. Interestingly, it has this feature, where it can send some of it’s components to low power state(when they are idle) even when the system is up and running. This will save the power significantly.

A system might be connected to a lot of USB devices such as Printers, finger print scanners, web cameras, Storage devices like external hard disks, card readers etc. These devices wont be running all the time and can be sent to a low-power state(when they are idle). Let’s say , the printer is active while all other USB devices are in idle state. With the Selective Suspension feature enabled, the system would suspend(i.e put them on low-power state) all the idle USB devices connected to the system. However , the Printer will be not be suspended as it is actively running.

From a system’s perspective, USB is a component in itself. Within this component there would be lot of USB devices connected. The system does not suspend whole of the USB component instead it selects a portion of the component that is to be suspended based on its state(idle or active). This is why it is called USB Selective Suspend Feature.

By default, this feature is Enabled on our System. But with certain setups,

  • The USB devices are not recognized throwing “USB device not recognized” error
  • The Connected USBs are disconnected automatically. At times , they do not turn back ON when needed.

In such cases, Disabling the USB Selective Suspend feature might help.
