USB is the English acronym for Universal Serial BUS, Chinese meaning is "Universal Serial Bus."It is not a new bus standard, but in the PC field of application interface technology. USB is the end of 1994 by Intel, Compaq, IBM, Microsoft and other companies jointly proposed.But until recently, it has been widely used before. From November 11, 1994 version of USB V0.7 released later, USB version has gone through years of development, up to now has been developed for the 2.0 version of the current expansion of the standard computer interface. At present, the main motherboard is USB1.1 and USB2.0, the USB version of the USB plug with a 4-pin plug as standard, the form can be used to daisy chain all of the peripherals connect up to 127 can be connected to external equipment, and no loss of bandwidth. USB needs of the host hardware, operating systems and peripherals support the three will work.The current motherboard is generally used to support the USB function control chipsets, motherboards are also equipped with USB interface socket, the socket and back in addition to, the motherboard also has USB pins is reserved, can be received through the connection box USB interface as a front in front of the convenience of the users (note that in connection to the motherboard manual to read and plans to connect must not be wrong then the damage of equipment).And USB interface can also be connected through a special USB drive to achieve two-plane interconnection line and can be extended through the Hub's interface more.USB has a faster transmission speed (USB1.1 is 12Mbps, USB2.0 is 480Mbps, USB3.0 is 5 Gbps), easy to use, support hot-swappable, connect flexible, independent power supply, etc., you can connect a mouse, keyboard, printer , scanners, camera, flash disk, MP3 machines, mobile phones, digital cameras, mobile hard drive, external floppy drive light, USB card, ADSL Modem, Cable Modem, etc., almost all of the external equipment.
USB is an external bus standard for the specification of computer and external device connectivity and communications. USB interface support equipment features plug-and-play and hot-swappable.
USB interface can be used to connect as many as 127 kinds of peripherals, such as mouse, modem and keyboard. USB since the introduction in 1996, has been successfully alternative serial and parallel port, and today a large number of personal computers and intelligent devices will be assigned one of the interface.
USB version
The first generation: USB 1.0/1.1 transfer rate for the maximum 12Mbps. Launched in 1996.
The second generation: USB 2.0 transfer rate up to the maximum 480Mbps. USB 1.0/1.1 and USB 2.0 interfaces are mutually compatible.
Third Generation: USB 3.0 maximum transfer rate of 5Gbps, downward compatible with USB 1.0/1.1/2.0
USB applications:
With the rapid development of computer hardware, peripherals, more and more keyboards, mice, modems, printers, scanners already known to all, digital cameras, MP3 players one after another, so much equipment, how to access a personal computer? USB is generated based on this objective.USB is a computer peripheral device is connected so that the standardization of a single interface, the specifications are from Intel, NEC, Compaq, DEC, IBM, Microsoft, Northern Telecom established contact.
Standard USB1.1 interface transfer rate of 12Mbps, but a USB device can only get a maximum bandwidth of 6Mbps. Thus if an external drive, can take up to six-speed CD-ROM, can not be high.Standard USB1.1 interface transfer rate of 12Mbps, but a USB device can only get a maximum bandwidth of 6Mbps. Thus if an external drive, can take up to six-speed CD-ROM, can not be high.
A USB interface can theoretically support 127 devices, but is still unable to achieve this figure. In fact, for a computer, the peripherals around the next few of the more than 10, so this figure is enough for us to use.
 USB also has a significant advantage is that support hot-swappable, meaning that in the case of the boot, you can safely connect or disconnect USB devices, true plug-and-play.
However, not all of the Windows system support USB. At present, Windows system, there are many different versions, in these versions, only the above versions of Windows98 system better USB support, while the other version of Windows does not support the integrity of the USB. For example, the retail version of Windows95 does not support USB, and only later bundled with the PC version of Windows95 support USB.
Windows95 versions in order to support USB.
Although USB devices are currently widely used, but it is more common USB1.1 interface, it is only the transmission speed of 12Mbps. For example, when you use USB1.1 scanner scan a picture of the size of 40M, the need for as long as 4 minutes. At such a pace, so that users find it very inconvenient, if there are a few pictures to scan, then you must have very good patience to wait any longer.
User demand is the driving force promoting the development of technology, manufacturers are also aware of the bottleneck. At this time, COMPAQ, Hewlett Packard, Intel, Lucent, Microsoft, NEC and the seven manufacturers PHILIPS this jointly developed the standard USB 2.0 interface.USB 2.0 will transfer data between devices increased the speed of 480Mbps, faster than USB 1.1 standard to about 40 times speed improvement for the users means that the greatest advantage is that users can use to more efficient external equipment, and has a wide range of speed peripherals can be connected to the USB 2.0 line, but without worrying about the data transmission bottleneck effect occurred.
So, if you use USB 2.0 scanner, on a totally different picture 40M So just a half a minute or so, on the blink of an eye later, the efficiency greatly enhanced. Moreover, USB2.0 can use the original definition of the same specifications USB cable, connector specifications are also identical to the premise that in the high-speed USB 1.1 as to maintain the outstanding characteristics, and,
USB 2.0 devices will not USB 1.X equipment in common use when the event of any conflict.
USB2.0 compatible with USB1.1, that is to say USB1.1 and USB2.0 devices can be general-purpose equipment, but at this time USB2.0 full-speed device can only work in the state (12Mbit / s).
USB2.0 high-speed, full-speed and low-speed three speed, high-speed is 480Mbit / s, full speed is 12Mbit / s, low speed is 1.5Mbit / s. Which is a full-speed and low-speed USB1.1 and USB1.0 compatible and designed to buy USB products therefore can not just listen to propaganda merchants USB2.0, but also to figure out is the high-speed, full-speed or low-speed devices.USB bus is a one-way bus, the main controller in the PC machine, USB devices can not initiate communication with the PC. USB device interoperability to solve communication problems, the manufacturers developed the USB OTG standard, allowing embedded system communicate with each other through the USB interface in order to get rid of the PC.
Rename the new USB2.0 specification of the original USB standard USB 1.1 into a USB 2.0 Full Speed (full version), at the same time, the original USB 2.0 into a USB 2.0High-Speed (speed version) and at the same time announced a new logo. It goes without saying that high-speed version of the course more than the speed of USB 2.0 full-speed version of USB 2.0.
USB vs IEEE1394
one, USB and IEEE1394 mainly the same as what? Both are a common external device interface. Both of which can quickly transfer large amounts of data. Can connect two different devices. Both support hot-swapping. Both do not have external power supply.
Second, USB and IEEE1394 What are the differences?
Transfer rate between the two different. USB and IEEE1394 transfer rate up faster than a really pale into insignificance. USB transfer rate is only 480Mbps, can only connect keyboard, mouse, and microphone, such as low-speed devices, and IEEE1394 can use 3.2Gbps, can be used to connect digital cameras, scanners and information appliances that require high-speed devices
Between the two different structures. USB connection to be in at least one computer, and must come to the realization of the need for HUB interconnection, the entire network can connect up to 127 devices.IEEE1394 do not need a computer to control all the equipment, do not need to HUB, IEEE1394 bridge can be used to connect multiple IEEE1394 network, that is to say in the use of IEEE1394 achieved after 63 IEEE1394 devices can be used to bridge other IEEE1394 network connection up to unlimited connections.
Intelligent different between the two. IEEE1394 network equipment can increase or decrease in its re-establishment of the network automatically. HUB is USB connected device to determine the increase or decrease. Application of two different levels. Now USB has been widely used in all aspects of almost every PC motherboard USB interfaces are set up, USB2.0 will further increase the range of USB applications. IEEE1394 is now only applies to audio, video and other multimedia.
USB On-The-Go supplement standard
USB On-The-Go Supplement 1.0:2001 released in December. USB On-The-Go Supplement 1.0a: 2003 was released 6 years, that is, the current version.
USB OTG is the USB On-The-Go acronym, is a recent development of technology, December 18, 2001 published by the USB Implementers Forum, mainly used in a variety of equipment or the connection between mobile devices for data exchange.In particular, PDA, mobile phones, consumer devices. Changes such as digital cameras, video cameras, printers and other equipment between a number of different standard connectors, as many as seven kinds of memory card format for data exchange between the inconvenience.
USB technology allows PC and peripherals through a simple way, the manufacturing costs will be modest data transmission rate of a variety of devices to connect together, we talk about the application of the above, to pass through the USB bus, as a PC peripheral, in the under the control of PC data exchange. However, this convenient way to exchange, once left the PC, the devices can not use USB port to operate, because there is no equipment to act as a PC from the same Host.
On-The-Go, is to realize that the OTG technology Host in the absence of circumstances, from the data transfer between devices.Such as digital cameras to connect directly to the printer through OTG technology, to connect two devices see the USB port, will produce an immediate print out the photos; also can be the data in digital cameras, through OTG is sent to the USB interface of the mobile hard disk , field operation there is no need to carry expensive memory card, or to carry a portable computer.
In OTG products, added some new features:
* new standard for compact design of the connectors and cables;
* in the traditional peripheral devices, an increase of Host ability to meet the point-to-point connection; * This the ability of the two devices can dynamically switch;
* Low power consumption to ensure that battery-powered USB can work under
After the use of OTG, does not affect the original equipment and PC connections, but the market has made more than one billion devices USB interface, but also through the Internet OTG.
About USB 3.0
Intel Corporation (Intel) and industry-leading companies together to form a group to promote USB 3.0 to develop 10 times faster than today's ultra-high-performance USB interconnect technology. This technology is by Intel, and Hewlett-Packard (HP), NEC, NXP Semiconductors and Texas Instruments Incorporated (Texas Instruments) and other co-developed applications, including personal computer, consumer and mobile products fast synchronous real-time transmission.With the increasing popularity of digital media and the increasing transmission of documents - even more than 25GB, fast synchronous real-time transmission has become the necessary performance requirements.
USB 3.0 backward compatibility with standards and technology, both traditional USB plug-and-play ease of use and functionality. The goal is to introduce technology to connect than the current level of more than 10 times faster products, using the USB cable the same framework.In addition to USB 3.0 specification is optimized to achieve lower power consumption and higher efficiency of the agreements, USB 3.0 port and cable to achieve backwards compatibility, as well as support for future optical transmission.
Intel set up a group to promote USB 3.0 on the hope that at the beginning of USB Design Institute (USB-IF) specifications for USB 3.0 can be used as trade associations. Integrity of the USB 3.0 specification is expected to launch in 2008 in the first half, USB 3.0 will be used initially in the form of discrete silicon.
Promotion Section, USB 3.0, including Hewlett-Packard, Intel, NEC, NXP Semiconductors and Texas Instruments, has been committed to protecting the USB device driver infrastructure and investment, USB, as well as the appearance of easy-to-use features, while continuing to carry forward the USB functionality of this remarkable technology .
"Since the first time since the installation of USB cable, NEC has always been supporters of USB technology", NEC Electronics SoC Systems Division, said Katsuhiko Itagaki, general manager, "It is time to further develop the already successful interface to meet the needs of the Internet market for large data transmission speed higher demand, so as to shorten the waiting time for users. "
"With the high-speed USB in the personal computing, consumer electronics and mobile market segments such as the universal, we expect will soon replace the USB 3.0 port USB2.0 high-bandwidth applications become the de facto standard",Texas Instruments vice president of Worldwide ASIC said Greg Hantak, "TI is excited about the excellent performance of the USB 3.0 will further expand the applications and USB for a better user experience."
USB 3.0 standard completed and published
By Intel, Microsoft, Hewlett-Packard, Texas Instruments, NEC, ST-NXP industry giants such as the composition of the USB 3.0 Promoter Group today announced that the organization responsible for developing a new generation of USB 3.0 standard has been officially completed and published. New specification provides ten times the transmission speed of USB 2.0 and higher energy efficiency, can be widely used in PC peripherals and consumer electronic products.
Completed the development of USB 3.0 standard has been transferred to the norms of management organizations USB Implementers Forum (referred to as USB-IF). The organization will work with hardware vendors to develop standards to support the new USB 3.0 hardware, but have to wait for the actual market for some time.
USB 1.0 is the first edition in 1996, appears, the speed is only 1.5Mb / s; two years after the upgrade to USB 1.1, also greatly speeds up to 12Mb / s, so far in some of the old equipment can also see that the standard interface; in April 2000, is currently widely used in the introduction of USB 2.0 speed reached a 480Mb / s, four USB 1.1 is ten times; Now eight over the first six months, USB 2.0 speed have been unable to meet the application needs, USB 3.0 will come into being, the largest transmission bandwidth up to 5.0Gb / s, which is 625MB / s, at the same time in the use of A-type interface When backwards compatibility.
IEEE has recently approved the new norms of IEEE1394-2008, but the new version of the transmission speed of FireWire is only 3.2Gb / s, the USB 3.0 is equivalent to little more than 60 percent. It is no wonder that Apple and other industry manufacturers generally lost interest in the technology.
USB 2.0 bus-based system for half-duplex line, can only provide a one-way data streaming, and USB 3.0 using the dual simplex four-wire differential signal lines, the club would support the concurrent two-way data stream transmission, which is the speed of the new rules that increase the key reason.
In addition, USB 3.0 also introduced a new mechanism for power management, support standby, such as a state of hibernation and suspension. Measuring instrument maker Tektronix (Tektronix) last month announced the first USB 3.0 for the test tools that can help developers to verify the new hardware design specification and the compatibility between.
USB 3.0 devices in the actual application will be referred to as "USB SuperSpeed", follow the previous USB 1.1 FullSpeed and USB 2.0 HighSpeed. Is expected to support the new controller will regulate the business in 2009 in the second half of the launch of consumer products are expected to be listed in 2010.
