Yes, the market is limited. But the USB devices exist, albeit not inside
the connector. From the myriads of GPIB equipped instruments I have seen
or used in labs less than 1% was connected. If they dropped the prices
they would sell a lot more adapters since many folks have simply
abandoned the GPIB capability of their instruments for cost reasons. The
advent of digital cameras for screen shots probably did the rest.

It doesn't require much power.
