USB

A USB system has an asymmetric design, consisting of a host, a multitude of downstream USB ports, and
multiple peripheral devices connected in a tiered-star topology. Additional USB hubs may be included in
the tiers, allowing branching into a tree structure, subject to a limit of 5 levels of tiers. USB host may have
multiple host controllers and each host controller may provide one or more USB ports. Up to 127 devices,
including the hub devices may be connected to a single host controller.
USB supports four data rates:
A Low Speed (1.1, 2.0) rate of 1.5Mbit/s (187.5kB/s) that is mostly used for Human Interface Devices
(HID) such as keyboards, mice, and joysticks.
A Full Speed (1.1, 2.0) rate of 12Mbit/s (1.5MB/s). Full Speed was the fastest rate before the USB 2.0
specification and many devices fall back to Full Speed. Full Speed devices divide the USB bandwidth
between them in a first-come first-served basis and it is not uncommon to run out of bandwidth with
several isochronous devices. All USB Hubs support Full Speed.
A Hi-Speed (2.0) rate of 480Mbit/s (60MB/s).
A SuperSpeed (3.0) rate of 5Gbit/s (625MB/s)
