In our final iteration, we will continue to improve the script by adding deduplication of processed entries and improving upon the output. Although the second iteration introduced the logic for filtering out non-USB devices, it does not deduplicate the responsive hits. We will deduplicate on the device name to ensure that there is only a single entry per device. In addition, we will integrate our usb_lookup.py script from Chapter 2, Python Fundamentals, to improve the utility of our script by displaying USB VIDs and PIDs for known devices.
We had to modify the code in the usb_lookup.py script to properly integrate it with the setupapi script. The differences between the two versions are subtle and are focused on reducing the number of function calls and improving the quality of the returned data. Throughout this iteration, we will...
