Abstract
The invention discloses a USB (Universal Serial Bus) port mapping method and a computer readable storage medium. The method comprises the steps of acquiring a USB port corresponding to a USB device when the USB device is accessed to a mainframe; acquiring a drive program keyword of the USB device; acquiring a device instance route of the USB device according to the drive program keyword; acquiringdevice information of all USB devices accessed to the mainframe, wherein the device information includes a device parameter and the device instance route; matching the device instance route of the USB device with the acquired device information to obtain the device parameter of the USB device; and associating the USB port corresponding to the USB device with the device parameter of the USB deviceto obtain a mapping relation of the USB device. According to the USB port mapping method and the computer readable storage medium, rapid mapping between the USB port and the USB device can be realized to achieve the effect of rapid distinguishing, and the problem of complex parallel operations in the industry of mobile phone forensics is solved and the work efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of evidence collection, in particular to a USB port mapping method and a computer-readable storage medium. Background technique [0002] At present, in the mobile phone forensics industry, with the continuous increase of mobile phone capacity and more and more content used, the speed of forensics has become slower, and multi-channel parallel mobile phone forensics has become the contemporary focus. However, when multiple mobile phones are connected to the main unit, it is impossible to distinguish which mobile phone data the mobile phone data connected to each USB port actually corresponds to on the main unit. Therefore, when mobile phones of similar brands or models are connected to parallel evidence collection at the same time, it is easy to cause operational errors. If the evidence collection is completed, the mobile phone is unplugged by mistake. [0003] At present, the way to realize the mapping relat...
