This could be a potential device driver issue.
Please check the status of Universal Serial Bus Controllers in device manager within the OS.
Attempt to update the driver software for the individual devices under Universal Serial Bus Controllers.

You may also check behavior under safe mode.

In addition check if Windows updates are installed.

你好，

进入安全模式后USB接口依然无法使用。除了重新安装操作系统是否还有其他办法？

Prior to reinstalling OS,lets first confirm the hardware is fine.

Suggest booting to different media, such as HPE SPP or OS install disk and check for USB functionlity with mouse/keyboard.

If functional then we can rule out hardware problem.

Also have you checked if missing any windows updates?
