Devices Enable or Disable USB Selective Suspend in Windows 11

This tutorial will show you how to turn on or off USB selective suspend for a power plan in Windows 10 and Windows 11.

USB selective suspend is the ability to power down and later resume an idle USB device while the computer to which it is attached remains in the working state (S0). For energy-efficient operation—especially on mobile PCs—all USB devices and drivers should support selective suspend. Powering down a device when it is idle, but while the system remains in the S0 state, has the following significant advantages:

• Selective suspend saves power.
• Selective suspend can help reduce environmental factors such as thermal load and noise.

The USB selective suspend feature allows the hub driver to suspend an individual port without affecting the operation of the other ports on the hub. Selective suspension of USB devices is especially useful in portable computers since it helps conserve battery power. Many devices, such as fingerprint readers and other kinds of biometric scanners, only require power intermittently. Suspending such devices, when the device is not in use, reduces overall power consumption. More importantly, any device that is not selectively suspended may prevent the USB host controller from disabling its transfer schedule, which resides in system memory. Direct memory access (DMA) transfers by the host controller to the scheduler can prevent the system's processors from entering deeper sleep states.

1 Open the Control Panel (icons view), and click/tap on the Power Options icon.

2 Click/tap on the Change plan settings link to the right of the power plan (ex: "Balanced") you want to enable or disable USB selective suspend for. (see screenshot below)

This will usually be for your active power plan.

3 Click/tap on the Change advanced power settings link. (see screenshot below)


4 In Power Options, expand open USB settings and USB selective suspend setting. (see screenshot below step 5)

5 Select Enabled (default) or Disabled for what you want in the On battery and Plugged in drop menus, and click/tap on OK. (see screenshot below)

You will only see separate On battery and Plugged in settings if your device has a battery or connected to a UPS.

This option will apply to your current active power plan.

1 Open Windows Terminal, and select either Windows PowerShell or Command Prompt.

2 Copy and paste the command(s) below you want to use into Windows Terminal, and press Enter.
