Pyusb - Get USB device address through python

To get the USB device address using the pyusb library in Python, you can use the bNumEndpoints field from the device descriptor. Here's an example:

import usb.core # Find USB device dev = usb.core.find(find_all=True) # Iterate through all USB devices for device in dev: # Get device address address = device.address # Get device descriptor descriptor = device.get_device_descriptor() # Print device information print(f"Device Address: {address}") print(f"bNumEndpoints: {descriptor.bNumEndpoints}") print("----------------------")

In this example:

  • usb.core.find(find_all=True) is used to find all connected USB devices.
  • The script then iterates through each device, retrieves the device address (device.address), and gets the device descriptor using device.get_device_descriptor().
  • The bNumEndpoints field from the device descriptor indicates the number of endpoints on the USB device.

This is a simple example, and you may need to customize it based on your specific requirements or the type of information you want to retrieve about the USB devices.

Make sure to install the pyusb library before running the code:

pip install pyusb

Additionally, note that on some platforms, you may need special permissions or administrative privileges to access USB devices.
