In the last installment in this series I examined the role of USB 2.0 as the primary means of connecting a webcam to a host computer, and the inherent limitations involved. But USB 2.0 is just so 20th-century…what about the newer, SuperSpeed USB 3.0? Doesn’t this lightning-fast (5 Gbps!) bus promise to allow real 1080p or even 4K webcams? Cheap-as-chips!
The answer to that question is a definite maybe (many thanks to Ray Davies.) However, as a practical matter, USB 3.0 webcams basically don’t exist. Even so, it’s worth having a look a the relatively brief existence of USB 3.0.
