I want to know the answer to the following question:
How many companies developed USB's?
All the background I'm provided with is that "The goal was to make it fundamentally easier to connect external devices to PCs by replacing the multitude of connectors at the back of PCs, addressing the usability issues of existing interfaces, and simplifying software configuration of all devices connected to USB, as well as permitting greater data rates for external devices.". Is that enough to answer the question?
Answer: no
