USB Cable

Best USB Cables Store
USB（Universal Serial Bus） cables are required to connect most new electronic devices to computers and extending ports with USB hubs and USB switch boxes. Most electronic devices that are intended to be connected to a computer use USB 2.0 speed cables.
 
There are many different types of USB connections on different devices.

Pinouts of Standard, Mini, and Micro USB plugs. The white areas in these drawings represent hollow spaces. As the plugs are shown here, the USB logo (with optional letter A or B) is on the top of the overmold in all cases.
USB type A is the rectangular type found on the back of a computer.
USB A type:

USB type B is the square type found on the back of a printer. In order to connect a computer to a printer, you would need a USB type A male to USB type B male cable.
USB B type:

There are also several smaller USB connections used on portable devices. New Android cell phones and Blackberry cell phones use micro USB. Digital camera cables can be several different USB types including micro USB, mini USB 5 pin or mini USB 4 pin.
Mini B type:

We offer some USB adapters that can convert one USB type to another. In addition to the many cable options, we also carry USB boxes and products that can extend the use of USB. A USB hub can add additional USB ports to a computer that does not have enough. A USB switch box allows you to switch one USB device such as a printer between multiple computers. If you have to extend a USB cable farther than the 15ft maximum, try our CAT5 extender or USB extension repeater cable. USB over CAT5E carries USB 1.0 speeds up to 180 feet. Some older devices have serial connections, and not USB. They would require our USB to serial adapter. USB cables have become a part of our daily lives, and with USB hubs and USB switch boxes, more connections than ever are possible.

“A”male to “A” male/female USB cables are typically used to extend the reach of your existing USB A/B cable.or to use USB device such as memory stick on your desk instead of inserting it to the back of PC.
The Micro-USB connector is rated for 10,000 connect-disconnect cycles which is significantly more than the mini plug design,and now being widely adopted by cellphone and PDA manufactures. These include various types of battery chargers,allowing Micro-USB to be the single external cable link.
USB 2.0 cables provide transfer rates up to 480Mbps,and easily attach to any USB device A to B cables are used to connect from your USB port on Hub,PC or Mac to your USB device such as printer or scanner.

Version history
Pre releases
The USB standard evolved through several versions before its official release in 1996:

• ● USB 0.7: Released in November 1994.
• ● USB 0.8: Released in December 1994.
• ● USB 0.9: Released in April 1995.
• ● USB 0.99: Released in August 1995.
• ● USB 1.0 Release Candidate: Released in November 1995.

USB 1
Released in January 1996, USB 1 specified data rates of 1.5 Mbit/s (Low-Bandwidth) and 12 Mbit/s (Full-Bandwidth). It did not allow for extension cables or pass-through monitors (due to timing and power limitations). Few USB devices made it to market until USB 1.1, released in August 1998, which fixed problems identified in 1.0, mostly relating to hubs. 1.1 was the earliest revision to be widely adopted.
USB 2.0

          The Hi-Speed USB Logo
USB 2.0: Released in April 2000. Added higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 MBit/s) (now called "Hi-Speed"). Further modifications to the USB specification have been done via Engineering Change Notices (ECN). The most important of these ECNs are included into the USB 2.0 specification package available from USB.org:

• ● Mini-A and Mini-B Connector ECN: Released in October 2000. Specifications for Mini-A and B plug and receptacle. Also receptacle that accepts both plugs for On-The-Go. These should not be confused with Micro-B plug and receptacle.
• ● Errata as of December 2000: Released in December 2000.
• ● Pull-up/Pull-down Resistors ECN: Released in May 2002.
• ● Errata as of May 2002: Released in May 2002.
• ● Interface Associations ECN: Released in May 2003. New standard descriptor was added that allows multiple interfaces to be associated with a single device function.
• ● Rounded Chamfer ECN: Released in October 2003. A recommended, compatible change to Mini-B plugs that results in longer lasting connectors.
• ● Unicode ECN: Released in February 2005. This ECN specifies that strings are encoded using UTF-16LE. USB 2.0 did specify that Unicode is to be used but it did not specify the encoding.
• ● Inter-Chip USB Supplement: Released in March 2006.
• ● On-The-Go Supplement 1.3: Released in December 2006.USB On-The-Go makes it possible for two USB devices to communicate with each other without requiring a separate USB host. In practice, one of the USB devices acts as a host for the other device.
• ● Battery Charging Specification 1.1: Released in March 2007 (Updated 15 Apr 2009).Adds support for dedicated chargers (power supplies with USB connectors), host chargers (USB hosts that can act as chargers) and the No Dead Battery provision which allows devices to temporarily draw 100 mA current after they have been attached. If a USB device is connected to dedicated charger, maximum current drawn by the device may be as high as 1.8 A. (Note that this document is not distributed with USB 2.0 specification package only USB 3.0 and USB On-The-Go.)
• ● Micro-USB Cables and Connectors Specification 1.01: Released in April 2007.
• ● Link Power Management Addendum ECN: Released in July 2007. This adds a new power state between enabled and suspended states. Device in this state is not required to reduce its power consumption. However, switching between enabled and sleep states is much faster than switching between enabled and suspended states, which allows devices to sleep while idle.
• ● Battery Charging Specification 1.2:Released in December 2010. Several changes and increasing limits including allowing 1.5A on charging ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5A and allowing a maximum current of 5A.
