> I doubt there's actually millions of hardware vendors.

Almost certainly correct because there are only 2^16 USB manufacturer IDs, of which (warning, Google AI quick result...) only 3400 are used. Tiny vendors of e.g. USB drives often seem to use the vendor and device ID of the interface chip manufacturer, but that's probably a good filter for really unimportant ones. Of course not every device has USB, but most major hardware vendors implement USB somewhere and have an official USB vendor ID.
