https://hackaday.com/2021/06/24/breaking-down-the-usb-keyboard-interface-with-old-fashioned-pen-and-paper/

What is better for gaming, old PS/2 style keyboards, or modern USB devices? [Ben Eater] sets out to answer this question, but along the way he ends up breaking down the entire USB keyboard interface.

It turns out that PS/2 and USB are very, very different. A PS/2 keyboard sends your keystroke every time you press a key, as long as it has power. A USB keyboard is more polite, it won’t send your keystrokes to the PC until it asks for them.

https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/capture-and-view-ing-usb-traces-with-microsoft-message-analyzer-

Summary

Microsoft Message Analyzer installation and setup
Capture and view live USB traces
You can use Microsoft Message Analyzer (MMA) to capture and view live USB traces, or view an existing trace.

Instead of capturing traces by using the command line tool, logman, and then parsing them in Netmon 3.4, you can perform all those tasks from a single GUI.

First of all let me thank you for sharing you knowlage.
Would it be worth trying USB data Capture such as this – http://www.eltima.com/products/usb-capture/
