How a System Perspective Slashes the Size of a USB 2.0 Device Core
USB 2.0 is a dramatic improvement over USB 1.1. Among other things, it’s 40 times faster and has new flow-control features that use bus bandwidth more efficiently. Yet it’s fully backward-compatible with existing USB 1.1 products. This combination of higher performance and broad compatibility almost guarantees that USB 2.0 will succeed in the marketplace -- a market that has already embraced USB 1.1 in personal computers, peripherals, digital cameras, industrial equipment, and many other applications.
