Internally, there's more than one device involved, and the actual
FireWire controller is only the last one. What particular device did
Windows complain about?

There is partial degree of reliability. Either the port has been
constructed to be a FireWire port with a USB jack (where the adapter
just maps the pins back), or it doesn't work at all.
