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.
If a USB device isn’t working correctly, you can try to disable selective suspend on Windows 10. That may cause your computer to draw more power, but it may help to identify and fix the problem as well.
Open Control Panel. Click on Hardware and Sound. Click on Power Options.
Under “Preferred plan,” click the Change plan settings link for the plan you’re currently using. (If you change the settings on the power plan that isn’t active, this won’t work.)
Click the Change advanced power settings link.
Expand USB settings. Expand USB selective suspend setting.
Here, you have two situations to work with. Choose the Enabled option for both On battery and Plugged in situations. Click the Ok button to save your new settings to Enable USB Selective Suspend in Windows 10.
If u wanna disable Select Disabled from the drop-down menu.
