2. Introduction Characteristics of USB System Model What needs to be done Platform Issues Conceptual Issues Timeline Characteristics of USB (1.1 specification) Up to 127 devices on one Bus Hierarchical structure with hubs Up to 12Mbps bandwidth (greater in 2.0) All connections are hot-plug able All communication is between host and device. No device-device communication. Devices can belong to generic type classes, with generic device drivers.
