1. The most direct method is to turn off the computer host power socket.
2. Or enter the BIOS-PowerManagementSetup-EuPSupport is set to [Enabled]. In this case, select the motherboard's power management mode to consume less than 1 watt when the system is shut down (S5 standby mode). When this function is enabled, the following four functions will have no effect: power management event wake-up function, mouse power-on function, keyboard power-on function and network wake-up function.
3. Or set the "USB wakeup" jumper of all USB interfaces to "OFF". This jumper is designed to provide +5VSB for USB devices to provide USB boot and wake-up functions. To turn off this function, just set "USBWP1_EN", "USBWP2_EN", and "USB01_PWR" to "1-2". USB wake-up function can be blocked.

Interface detection and protection technology:
With the emergence of malicious USB attack tools headed by Teensy, researchers have begun to pay attention to USB interfaces Research on detection and protection technology. In 2012, Wang and others, researchers at George Mason University in the United States, proposed an improved version of the USB protocol-USBSec.
The core idea of ??this protocol is that only when identity authentication is completed between the host and the peripheral device, the enumeration process of the USB device can be carried out. The signature algorithm in this protocol uses Diffie-Hellman encryption. The host provides identity authentication information to the peripheral, and the peripheral verifies the authentication information based on its own authorized host key list. If both parties pass the verification.
The USB device enumeration process will be carried out, otherwise the connection will be terminated. This technology strengthens the communication security between the host and peripherals through two-way authentication, and is highly protective. However, it modifies the universal USB protocol, which is not applicable to USB devices currently on the market and has great limitations.
