This disclosure relates to the field of recognizing a security attack by a USB device on a computer. This

method involves recognizing when a corrupted device would surreptitiously reconfigure itself and attack

the computer system that is attached to.

The universal serial bus (USB) is a flexible interface for connecting all kinds of computer input and

output device. Computer systems are generally very open and facilitate both physically accessible “walk

up ports” to the exterior of the chassis and pre‐install a very broad number of “lass device”drivers that

read the configuration and identification of the device and automatically enable the plugged‐in device.

USB is also commonly used as an internal connection to the computer, because of its low cost for

implementation such devices such as touchscreens, fingerprint readers, memory card readers, etc. may

function by the connection of USB to the device.
