Hello, I've just read about this usage method, which I've totally missed the other times:

Intrigued by the possibility of generating the dump in a single operation, avoiding to map every single usb port manually, I did a search on Google to get this tool.
Unfortunately the search didn't return anything.
So I've tried on github, and found this repo: https://github.com/Goldfish64/UsbDumpEfiPkg
I'll give it a try now. Anyway, wouldn't be a good idea to add a link in the readme file?
🥂
