How to read debug?

Question

Python

My previous question What drivers should I install to make the PyUSB 1.0 library work? . From the link https://github.com/pyusb/pyusb/blob/master/docs/faq.rst ran the code

import os 
os.environ ['PYUSB_DEBUG'] = 'debug' 
import usb.core 
usb.core.find ()

which gave me

2021-04-21 13:05:30,489 DEBUG:usb.backend.libusb1:_LibUSB.__init__()
2021-04-21 13:05:30,497 INFO:usb.core:find(): using backend "usb .backend.libusb1"
2021-04-21 13:05:30,497 DEBUG:usb.backend.libusb1:_LibUSB.enumerate_devices()
2021-04-21 13:05:32,833 DEBUG:usb.backend.libusb1:_LibUSB.get_device_descriptor( )
2021-04-21 13:05:32,833 DEBUG:usb.backend.libusb1:_LibUSB._finalize_object()

but I don't understand how to read it.
