Please refrain from calling this a duplicate, I am completely new to idea of accessing USB devices via Python.

The other questions and answers were often too high level for me to comprehend.

I have a qr code scanner that is USB plug and play. 

I can't find it on the command line for whatever reason and it has me stumped.

When the scanner scans a QR code I want its data to be sent to my python script so I can set it to a variable for comparison against a database. 

I don't understand how to access a USB device and retrieve the information with Python. 

I have read quite a bit about it and still nothing.

Is there a some-what simple way of doing this?
