USB vendor/product IDs are for unique hardware designs/firmware so that they are easily recognized by their respective drivers, not each unique piece of hardware. For example, Logitech's vendor ID (they probably have a few) allows them 64,000 different keyboard, mouse, etc. products of which they can manufacture millions of units. I don't know of any vendor ID that has exhausted their product ID space which includes companies like Microchip which give away PIDs on their VID when you use their USB chips (with under 10k units in production)
