USB Device Detection Script

This is a simple C script that identifies and displays USB devices connected to a Linux-based system. It reads from the /sys/bus/usb/devices/ directory to list the names of connected USB devices.

How It Works

The script:

1. Opens the /sys/bus/usb/devices/ directory, where USB device information is stored.
2. Searches for entries containing : in their names, as these typically correspond to USB devices.
3. Reads each device's product file to retrieve the device name.
4. Prints each USB device’s name to the console.

Prerequisites

• Operating System: Linux-based (the script relies on the /sys file system, which is standard in Linux for hardware information).
• C Compiler: gcc or any other C compiler.

Usage

1. Clone or Download the repository.

2. Compile the Script:

   gcc usb_devices.c -o usb_devices

3. Run the Script:

   ./usb_devices

4. Output:

   The script will display a list of USB devices currently connected to your system.

   Connected USB devices:
   Device: USB Keyboard
   Device: USB Mouse
   Device: External USB Drive
   

Code Explanation

list_usb_devices()

The list_usb_devices() function opens the /sys/bus/usb/devices/ directory and iterates through each entry:

• It identifies entries with : in the name, which generally represent USB devices.
• For each entry, it attempts to read the product file to retrieve the device's name.

main()

The main() function simply calls list_usb_devices() to execute the USB detection logic.

Notes

• This script is designed for Linux systems; it will not work on Windows or macOS without significant changes.
• The script reads directly from system files; it may require root permissions to access certain USB device information depending on your system’s configuration.
