Definitions
The layered communication protocol defined by the Universal Serial Bus specification, governing how hosts enumerate, configure, and exchange data with connected devices through a tiered star topology using control, bulk, interrupt, and isochronous transfer types.
In plain English: The set of rules that allows your computer to detect, configure, and talk to devices plugged in via USB cables.
