3. INTRODUCTION
Universal Serial Bus are the standard connection for
a variety of electronic peripherals with the PC.
The latest version of USB is named as USB 3.0 or
SUPERSPEED USB announced by Pat Gelsinger at
the Intel Developer forum.
Nicknamed super speed USB because of the
significant speed improvements over existing USB
specifications.

4. HISTORY
There have been 3 versions released prior to 3.0
1) USB 1.0 in January 1996- data rates of 1.5 Mbps.
2) USB 1.1 in September 1998-first widely used
version of USB provides 12 Mbps.
4
5. 3) HIGH SPEED USB OR USB 2.0
Released with speeds of 480 Mbps.
Released in 2000.

6. NOW
SUPERSPEED USB OR USB 3.0
Predicted speed of 5 Gbps.
Developed on November 17,2008.

7. WHY THE UPGRADE?
Mainly the need for faster
transfer rates in devices such as
hard drives, flash card readers &
DVD, Blue-ray & HD DVD
optical drives.
User applications demanding a
higher performance connection
between the PC & peripherals.

8. USB 3.0 FEATURES
10X performance increases over USB 2.0;
Low power consumption;
Hot swappable-easily plug & play;
Compatibility -full duplex;
Longer maximum cable length.
Backward compatible
-USB 2.0 device will work with USB 3.0 host
-USB 3.0 device will work with USB 2.0 host

10. MAXIMUM USEFUL DISTANCE
USB 1.1 maximum cable length is 3 meters(9.8 ft).
USB 2.0 maximum cable length is 5 meters(16 ft).
USB 3.0 cable length is available with following
transfer rates:-
15 gigabits per second (Gbps) at 1 meter;
10 Gbps at 2 meters;
5 Gbps at 5 meters. 10
11. USB 3.0 CONNECTOR
Std A - Same interface as USB 2.0
Standard-A connector, but with
added pins for USB 3.0 Super-
Speed signals.
Std B - Defined for relatively
large, stationary peripherals such
as hard drives and printers.
-Visually different from USB 2.0
Standard-B connector.

13. THE FUTURE-SMART PHONES AND
TABLETS WILL HAVE USB 3.0 PORTS IN
2012
In the future, smart phones will have a USB 3.0
device port acting as a peripheral to sync with your
laptop.
HP has said it will bring USB 3.0 to a majority of its
high-performance and business laptops later this year.
13
14. The USB Standards Organization announced in Jan
2012 that USB 3.0 SS ports would be making their
way to smart phones and tablet devices this year, and
most on the market by the end of 2012 would support
the 3.0 standard.
Intel integrates USB 3.0 into chipset.
Windows 8 begins USB 3.0 support.
14
15. CONCLUSION
The USB 3.0 is supporting a speed of about 5 Gbps
i.e. ten times faster than 2.0 version;
So hopefully by the help of this Super Speed data
transfer rate the USB 3.0 will be replacing many of
the connectors in the future.
