Hi-Speed USB 2.0

USB (Universal Serial Bus) is an interface technology for the
serial transmission of digital data. The original standard
(USB 1.x) had an interface transfer rate of up to 12 Mbps.
USB 2.0 has a maximum interface transfer rate of 480 Mbps
(60 Megabytes/s) –– that's up to 40 times faster than USB 1.
Interface transfer rates up to 480 Mbps
480 Mbps is equivalent to 60 Megabytes per second. 480
Mbps is the maximum speed; data transfer rates will vary
depending on a number of factors, including available CPU
resources.
Supports up to 127 devices
Connecting more than one or two USB devices to a computer
usually requires the use of one or more USB-equipped hubs;
a hub can typically accommodate several USB devices.
Master-slave architecture
The computer (the master) dictates data flow to, from, and
between attached USB devices (the slaves).
Cable length up to 5 m
On-bus power up to 2.5 W
USB can supply up to 2.5 W of electrical power, making it
possible to use many low-power-consumption devices with-
out a dedicated electrical connection.
