Introduction

With the advent of technology, USB devices are widely used for transferring data from one device to another. Retrieving information about USB devices can be a vital task, especially for forensic purposes. Python is a general-purpose programming language that has gained popularity among developers for its easy-to-learn syntax and powerful data analysis capabilities. In this article, we will explore how Python can help you effortlessly retrieve USB device information.

What is USB device info?

USB device info comprises various attributes that describe the device’s hardware, software, and configuration settings. This information includes the manufacturer, product name, serial number, vendor ID, product ID, device class, and more. Retrieving this information from a USB device can be useful for several purposes, such as determining the device’s compatibility, identifying counterfeit products, diagnosing technical issues, and forensic investigations.

Traditional ways of retrieving USB device info

Traditionally, retrieving USB device information requires complex commands or third-party software, which can be time-consuming and challenging for non-technical users. The Windows Management Instrumentation (WMI) interface provides a way to retrieve information programmatically, but it requires specialized knowledge of the interface’s syntax and structure.

How Python simplifies USB device info retrieval

Python offers various libraries and modules that simplify USB device information retrieval. The PyUSB library, for instance, provides an abstraction layer over the USB protocol, enabling developers to communicate with USB devices easily. The PySerial library allows reading and writing data on serial ports, including USB. Additionally, the HID library supports the creation of Human Interface Devices using USB.

Using Python to retrieve USB device info

Python has inbuilt libraries like os, sys, and platform that can help retrieve USB device info. The subprocess library can also execute system-level commands and shell scripts, including retrieving USB device info. Developers can also use external libraries like the PyUSB library to retrieve USB device info.

Retrieve USB device info using PyUSB

The PyUSB library provides an easy way to interact with USB devices. To retrieve USB device info using PyUSB, we need to install the library using pip and then write the following code:

Prerequisites

Before implementing the below code, ensure that PyUSB library is installed on your computer:

python -m pip install pyusb

Code implementation

import usb.coreimport usb.util     def get_usb_info():    device = usb.core.find(find_all=True)    for cfg in device:        print(----------------------)        print(fVendor ID: {hex(cfg.idVendor)})        print(fProduct ID: {hex(cfg.idProduct)})        print(fDevice Class: {cfg.bDeviceClass})        print(fSerial Number: {cfg.serial_number})        print(----------------------\n)    if __name__ == '__main__':    get_usb_info()

Retrieve USB device info using PySerial

The PySerial library helps in reading and writing data on serial ports, including USB. To retrieve USB device info using PySerial, we need to write the following code:

Prerequisites

Before implementing the below code, ensure that PySerial library is installed on your computer:

pip install pyserial

Code implementation

import serial.tools.list_ports     def get_usb_info():    ports = list(serial.tools.list_ports.comports())    for port in ports:        print(----------------------)        print(fDevice name: {port.device})        print(fProduct ID: {port.pid})        print(fVendor ID: {port.vid})        print(fDescription: {port.description})        print(----------------------\n)    if __name__ == '__main__':    get_usb_info()
