That's $2k PERIODICALLY so that they maintain your

checked, anyway. Not a one-time fee. It's a big hurdle towards
developing your own hardware on a pretty common bus (similar problems
exist for PCI). And with only 16 bits of address space, there's no
reliable way to generate your own universally unique ID (one of the
few times you'll see me advocating for the use of UUIDs).
Well, to be fair, Microchip and FTDI both have sub-license programs that
are available for little more than asking.
Or you can copy the Chinese scheme--pull the VID and PID out of thin air
or just piggyback your PID on to some defunct (or non-defunct) company's
VID.
You can witness how common this practice is by browsing the IDs at
