USB permits hot plug-in. Theres no need to shut down, plug in, reboot\
 and run set-up to 
install peripherals. And no need to go through the reverse process to un\
plug a device. 
In short, USB transforms todays Plug-and-Pray into true Plug-and-Play\
! 
Hub
 
A Universal Serial Bus device that provides additional connections to th\
e Universal Serial Bus. 
Hubs are a key element in the plug-and-play architecture of USB. The Fig\
ure shows a typical hub. 
Hubs serve to simplify USB connectivity from the users perspective prov\
iding low cost and 
complexity.
Hubs are wiring concentrators and enable the multiple attachment charact\
eristics of USB. 
Attachment points are referred to as ports. Each hub converts a single a\
ttachment point into 
multiple attachment points. The architecture supports concatenation of m\
ultiple hubs. 
The upstream port of a hub connects the hub towards the host. Each of th\
e other downstream ports 
of a hub allows connection to another hub or function. Hubs can detect, \
attach and detach at each 
downstream port and enable the distribution of power to downstream devic\
es. Each downstream 
port can be individually enabled and configured at either full or low sp\
eed. The hub isolates low 
speed ports from full speed signaling. 
A hub consists of two portions: the Hub Controller and Hub Repeater. The\
 repeater is a protocol-
controlled switch between the upstream port and downstream ports. It als\
o has hardware support 
for reset and suspend/resume signaling. The controller provides the inte\
rface registers to allow 
communication to/from the host. Hub specific status and control commands\
 permit the host to 
configure a hub and to monitor and control its ports. 
Device 
A logical or physical entity that performs a function. The actual entity\
 described depends on the 
context of the reference. At the lowest level, device may refer to a sin\
gle hardware component, as 
in a memory device. At a higher level, it may refer to a collection of h\
ardware components that 
perform a particular function, such as a Universal Serial Bus interface \
device. At an even higher 
level, device may refer to the function performed by an entity attached \
to the Universal Serial Bus; 
for example, a data/FAX modem device. Devices may be physical, electrica\
l, addressable, and 
logical.

Downstream 
The direction of data flow from the host or away from the host. A downst\
ream port is the port on a 
hub electrically farthest from the host that generates downstream data t\
raffic from the hub. 
Downstream ports receive upstream data traffic. 
Upstream 
The direction of data flow towards the host. An upstream port is the por\
t on a device electrically 
closest to the host that generates upstream data traffic from the hub. U\
pstream ports receive 
downstream data traffic.
