This interface can be said is the most common interfaces, which interface to plug the wrong kind of superior performance against the volume is relatively small, so more and more companies are favored to win, this interface is now widespread in the reader, MP3, digital cameras and mobile hard disk. The next picture shows: Sony F828 Mini B-type 5Pin on the interface device is currently using this interface, there are SONY cameras, camcorders and MP3, Olympus camera and voice recorder, Canon and HP digital cameras, etc., a considerable amount of variety. Common Mini B 4Pin Interface Type: In addition to the front we see the most common interface to Mini B type 5Pin outside, Mini B-type There are many other interfaces, some of which are more common. Mini B type 4Pin right picture: Mini B type under the interface 4Pin Pictured: Mini B type 4Pin interface adapter cable that interfaces commonly found in the following brands of digital products: Olympus C-series and E series, most of Kodak's digital camera, Samsung's MP3 products (such as Yepp) , SONY's DSC series, Compaq IPAQ series of products ... ... Fuji Mini B type 4Pin Flat Interface: Mini B 4Pin There is also a form of type, that is, Mini B type 4Pin Flat. As the name implies, this interface type than the Mini B 4Pin to flatter, the application of the device is also more extensive. Fuji Mini B type 4Pin Flat right picture: Mini B 4Pin Flat interface, this interface type and speak in front of INI B-type 4pin very similar, but the connection is more flat, occupied by the smaller. This interface is common in the following equipment: Fuji's FinePix series, the Casio QV series cameras, Konica products. We see that Fujitsu machines are more in this interface is almost old Some models are all such interfaces. But it is worth noting that, Fuji S5000 and S7000 in the latest has been abandoned this interface, switched to Mini B 5Pin camp. Nikon's exclusive, Mini B type 8Pin Interface: Mini B-type addition to the previous 4Pin and 5Pin, there is a 8Pin's, and this joint in the other devices the chance to appear on very few, usually in digital cameras. Mini B-type interface also has 3, a species is the common type, one is the Round (round) type, there is a 2 × 4 layout of the flat interfaces. MINI B type 8Pin right picture: Mini B type 8Pin this interface for the interface device, according to I understand that currently only a Nikon Coolpix 775 models of products using this interface. Mini B type 8Pin Round Left: Mini B type 8Pin Round interfaces that interface and compared to the previous ordinary type, that is, the original D- connector into the round connector, and in order to prevent accidental insertion of a bulge in the side of the design. This connector can be seen in some Nikon digital camera, CoolPix series more common. While Nikon has always insisted on using this interface, but in some Newer models, such as D100, and CP2000 are also using the highest popularity Mini B type 5Pin interface. almost to spread, 8Pin 2 × 4 interface: we've seen in addition to Mini B type 5Pin the interfaces, I Here we must also think this interface is very familiar with this interface has also been quite popular. Mini B type 8Pin 2 × 4 Pictured: Mini B type 8Pin 2 × 4 interface, this interface is a relatively common interface to the For example, we are familiar with the famous iRiver MP3 series, which is known as Since the 3XX series comprehensively into Mini B type 5Pin the interface, this specification was not Mini B type 5Pin eye-catching. corresponds to part of the picture

Jane The evolution of the above USB until recently, however, it was widely applied. from the November 11, 1994 version released later USB V0.7, USB version has gone through years of development, has now been developed for the 3.0 version, a current computer The standard extension interfaces. the current board is mainly used in USB1.1 and USB2.0, USB version of the compatibility between the well. USB with a 4-pin (USB3.0 standard 9-pin) connector plug as standard, using you can daisy chain connecting all the peripherals, up to 127 external devices can be connected, and will not damage the bandwidth. USB requires a host of hardware, operating systems and peripherals to support three areas to work. The current board is generally used support the USB function control chipsets, motherboards are also equipped with USB interface socket, and the back of the socket in addition, the board also set aside a USB pins on the front chassis received through the connection interface to a front USB easy to use (note that in connection to carefully read the motherboard manual and press the graph connected, do not take the wrong leaving equipment damage). and the USB interface can also be connected through a special USB cable to achieve double machine interconnection, and can be Hub expand more interfaces. USB has a transmission speed (USB1.1 is 12Mbps, USB2.0 is 480Mbps, USB3.0 is 5 Gbps), easy to use, support hot plug, connecting flexible, independent power supply, etc., can connect a mouse, keyboard, printer, scanner, camera, flash drive, MP3, mobile phones, digital cameras, mobile hard drive, external optical floppy, USB card, ADSL Modem, Cable Modem, etc., almost all of the external devices. USB interface can be used to connect up to 127 peripherals, such as mouse, modems, and keyboards. USB since the launch in 1996, had successfully replaced the serial port and parallel port and is now a large number of personal computers and intelligent devices will be equipped with one interface. difference between the version of USB version of the title of the maximum transmission rate of the maximum output current agreement rate of release time USB1.01.5Mbps (192KB / s) low speed (Low-Speed) 500mA1996 on January USB1.112Mbps (1.5MB / s) full-speed (Full-Speed) 500mA1998 on September USB2.0480Mbps (60MB / s) high speed (High-Speed) 500mA2000 on April USB3.05Gbps (640MB / s) speed (Super-Speed) 900mA2008 application on November USB computer hardware with the rapid development of increasing number of peripherals, keyboard, mouse, modems, printers, scanners, has long been known, digital cameras, MP3 players followed, so much equipment, how to access the personal computer? USB is generated based on this purpose. USB is a computer peripheral device is connected to standardization and simplification of the interface, its specifications by the Intel (Intel), NEC, Compaq, DEC, IBM (Business Machines Corporation), Microsoft (Microsoft), Northern Telecom contact developed. USB1. a standard interface transfer rate of 12Mbps, but a USB device can be a maximum bandwidth of 6Mbps. So to the external drive, can take up to six-speed CD-ROM drive, can not be higher. And to real-time playback of MPEG-1 VCD movies at least 1.5Mbps bandwidth of USB to do this are, but four times to complete the large amount of data in the DVD MPEG-2 video playback, USB may be very difficult, and when coupled with AC-3 audio data, USB device to be difficult to achieve real-time broadcast. a USB interface, can support 127 devices theoretically, but not currently be achieved. In fact, for a computer, the connection of peripherals, there is little more than 10, and Therefore, this number is enough for us to use. USB there is a significant advantage is hot-swappable, meaning that the case in the boot, you can safely connect or disconnect USB devices, to achieve true plug and play. However, not all Windows systems support USB. Currently, Windows system, there are many different versions, in these versions, only the version of the system above Windows98 USB support is better, while others can not completely support the Windows version and USB . For example, the retail version of Windows95 does not support USB, and only later bundled with the PC version only supports Windows95 USB. Although the current USB devices are widely used, more generally, USB2.0 interface, 480Mbps transmission speed of each seconds. user demand is the driving force to promote technological development, manufacturers are also aware of this bottleneck. At this time, COMPAQ, Hewlett Packard, Intel, Lucent, Microsoft, NEC, and PHILIPS these seven companies jointly developed a USB 2.0 interface standard. USB 2.0 data transfer between the devices increased speed of 480Mbps, faster than the USB 1.1 standard is about 40 times the speed increase is the greatest benefit for the users means that users can use to more efficient external devices, but also has a variety of speed peripherals can be connected to the USB 2.0 line, but also do not need to worry about data transfer bottleneck effect occurs. So, if you use USB 2.0 scanner to a totally different scan a picture just 0.1 seconds 4M so, blink of an eye later, efficiency is greatly improved. And, USB2.0 definition can use the same specifications as the original USB cable, connector specifications are exactly the same as the premise of high-speed USB 1.1 to maintain the outstanding characteristics and, USB 2.0 devices and USB 1.X device will not be shared when any conflict. USB2.0 compatible with USB1.1, USB1.1 devices that USB2.0 devices can be generic, but 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 operating speed, speed is 480Mbit / s, full speed is 12Mbit / s, low speed is 1.5Mbit / s. full-speed and low speed which is compatible with USB1.1 and USB1.0 and design, so choose USB products promotional business can not just listen 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 PC,, USB devices can not initiate communication with the PC machine. In order to solve communication problems each USB device, the company has developed a USB OTG standard, allowing the embedded system through the USB interface to communicate with each other to get rid of the PC. New USB USB2.0 specification renamed the original USB 1.1 standard will be turned into a USB 2.0 Full Speed (full version), while the original USB 2.0 into a USB 2.0High-Speed (speed version) , and also announced a new logo. self-evident, high-speed version of USB 2.0 full-speed version of the speed course over USB 2.0. PC USB port to provide maximum current 500mA. USB vs IEEE1394 one, USB and IEEE1394 same main point What? both of which are a common external device interface. both are fast transfer of large amounts of data. Both can connect many different devices. both support hot-plugging. both are without an external power supply. II , USB and IEEE1394 What are the differences? transmission rate between the two. USB transfer rate and the rate of IEEE1394 is really trivial compared to the. USB transfer rate is now only 480Mbps, can only connect keyboard, mouse, microphone, etc. low-speed devices, and IEEE1394 can use 3.2Gbps, can be used to connect digital cameras, scanners, and information appliances that require high-speed equipment. two different structures. USB connection must be at least one computer, and must be required to HUB interconnected, the entire network can connect up to 127 devices. IEEE1394 do not need a computer to control all devices, do not need to HUB, IEEE1394 bridge can connect multiple IEEE1394 network, that is achieved in 63 with IEEE1394 IEEE1394 device can also be used after the bridge will connect the other IEEE1394 network, to unlimited connections. two different intelligence. IEEE1394 network can increase or decrease in their devices automatically reset when the network. USB HUB to determine the connection is Changes in the equipment. Both the application of different levels. Now USB has been widely applied to various aspects of almost every PC motherboard USB interfaces are set, USB2.0 will further increase the range of USB applications. IEEE1394 now only be applied to audio, video and other multimedia. USB application and development trend of the expansion of the front USB interface, Front USB interface is located on the front panel USB expansion port. Currently, the use of various external devices USB interface, more and more , such as mobile hard drives, flash drives, digital cameras, etc., but in the use of these devices (especially the frequent use of mobile storage devices) every time they drill into the back of the chassis to use motherboard onboard USB interface, is obviously inconvenient. Front USB interface to give users in this area provides a good ease of use. At present, the front USB interface, has become almost standard chassis, no chassis, front USB interface has been very rare. Front USB interfaces to attached to the chassis using the USB cable connected to the motherboard front USB on the corresponding pin (usually 8-pin, 9-pin or 10 pin, two USB pairs, each of which use 4-pin USB transfers signal and power supply ) can be used on. In front USB interface connection must first read the motherboard manual and chassis manual and its related content, it can not be a wrong connection, or USB device or cause damage to the motherboard. In addition, because USB2 .0 interface output voltage 5V, output current is 500mA. to use the front USB interface, USB interface, front pay attention to the problem of insufficient power supply, large power consumption in the use of USB devices, to use an external power supply or directly using the chassis the rear of the motherboard onboard USB port, to avoid USB device is not used or damaged. USB hard disk box is currently the mainstream population, the biggest advantage is ease of use, support hot swap and plug and play. USB has two standards : one is the USB1.1 interface, the transmission speed is only 12Mbps, one is the USB2.0 interface, transfer rate up to 480Mbps. The current USB on the motherboard support USB1.1, but only the newer USB 2.0 motherboard can support, purchase select products based on individual circumstances, although the downward compatible with USB2.0 USB1.1, USB2.0 interface, it supports mobile hard disk box's more expensive than USB1.1. Wireless USB USB Developer Forum, Intel President and Chief the company's technical strategy officer, said Jeff Ravencraft, Wireless USB technology will help users connect to the printer in the use of personal computers, digital cameras, music players and external disk drives and other equipment, the cable connection from the complex to liberate. Wireless USB standard data transfer rate with the current wired USB 2.0 standard is the same, are second 480M, The difference is the wireless USB requires a PC or peripheral equipment, wireless transmitters and receivers to replace the cable connection. at the Intel Developer Forum held on the eve, Ravencraft said, the first use of this standard will be the external disk drives, digital cameras and printers. and more and more products will be in the third quarter of the market. To make the wireless USB standard to be practical, the need to improve some shortcomings of this technology. USB standards group announced a wireless Alliance specifications to ensure that only certified to allow the computer and peripherals connected via wireless USB. Ravencraft added, has been widely used USB standard a digital camera, scanner, cell phone, PDA, DVD recorders and other devices connected to personal computers. And Wireless Consortium specification details the requirements of the personal computer and peripherals to be connected via wireless USB, a computer can connect up to 127 peripherals. Wireless Consortium specification provides for two methods to establish a connection. The first method is a computer and peripherals before connecting cable, and then establish a wireless connection for later use. The second is peripheral to provide a series of numbers, when the user input to establish a connection to a computer inside. Wireless USB uses ultra-wideband technology for communication. 802.11g wireless local area network protocol currently used in the 2.4GHz frequency band near the short communications, and ultra-wideband technology is used from 3.1GHz to 10.6GHz frequency band for communication. UWB signal levels are low enough, so for the other wireless communication technologies, the impact of UWB signals similar to noise. Wireless network technology is now widely used IEEE 802.11 standard that is driven by Intel's Wi-Fi. this technology widely used in notebook computers, and even some Nikon and Canon digital cameras using this technology. The wireless USB technology is a completely different technology, as This technology is relatively simple while consuming only half of 802.11, so many companies are more willing to adopt Wireless USB technology. Ravencraft said that in the high-end mobile phones and digital cameras using 802.11 technology, the key is to solve the problem of battery life. The manufacturers have found that ultra-wideband technology is the solution to this problem the best way. at a distance of 10 feet within the computer, wireless USB devices per second transfer rate will remain 480M. If within 30 feet, the transmission rate drops to per 110M. However, with the technology, the wireless USB transfer rate will be more than 1G per second or faster. current UWB technology not only can be used for the wireless USB connection, you can also Bluetooth and IEEE 1394 or FireWire connection WiNet short-range connections to use. USB interface and data lines of different kinds of digital devices with a large number of popular, especially the popularity of MP3 and digital cameras, USB devices around us, more and more together. However, although these devices are based on a USB interface, but these devices are not exactly the same data line. These data cable to connect one end are the same PC, but when the end of the connecting device, usually because of volume and considering the various different interfaces. Most of digital products in addition to the cable connector connected to the PC are the same on the other end are also follow the standard specification. USB is a uniform transmission standard, but there are many kinds of interfaces, the most common is the computer we on the use of that flat, which is called A-type port, which has four connections, according to who is who were divided into male and female connectors interface with the public and the general online population, with the mother on the machine port. USB A public-mouth the right picture above is the most common type of public port USB A Mini B-type 5Pin common interface: The next step is the most common products in the digital interface, and the limited volume of digital products, it usually is the Mini B-type interface, but the Mini B-type interface, there are many types. Mini B type 5Pin the right of the picture shows the Mini B type 5Pin Interface Schematic
USB, is English Universal Serial BUS (Universal Serial Bus) stands, while the Chinese referred to as the the field of interface technology. USB interface supports Plug & Play and hot swap function devices. USB is the end of 1994 by Intel, Compaq, IBM, Microsoft and other companies jointly proposed.

USB 2.0 USB is the abbreviation for Universal Serial Bus in English, Chinese meaning is new applications in the field of computer interface technology. as early as 1995 to have a personal computer with a USB interface, but due to lack of software and hardware support, the personal computer's USB interfaces are idle unused. After 1998, With the Microsoft Windows 98, USB interface, built-in support for the module, coupled with the increasing number of USB devices, USB interface, it gradually entered the practical stage. In recent years, with a large number of USB-PC penetration, USB gradually become the standard interface for personal computers has been the general trend. On the host side, the latest version of the personal computer is almost 100% support USB; and in the peripheral side, the use of USB interface devices are also growing, such as digital cameras, scanners, joysticks, tapes and floppy drive, image equipment, printer, keyboard, mouse and so on. USB devices will be the reason why large number of applications, mainly has the following advantages: 1, hot-pluggable. This allows users to use an external device, do not repeat off the parallel or serial cable connected to the re-boot For users, the same 20G hard drive, USB hard drive, IDE hard drive to light half of the weight you want to carry large amounts of data, of course, USB hard drives will be the primary choice for the. 3, the standard uniform. all common is IDE interface, hard disk, keyboard, mouse, serial port, parallel port printer, scanner, but with USB, these applications all use the same peripherals and personal computer connection standard, then there will be a USB drive, USB mouse, USB printer, etc. and so on. 4, you can connect multiple devices. USB on the PC tend to have multiple interfaces,[link widoczny dla zalogowanych], several devices can be connected, if connected to a four-port USB HUB, it can be connected; four USB equipment, and so on, he can not even go to your home devices are also connected in a personal computer without any problems (Note: up to 127 devices can be connected). But why has emerged USB2 .0? It with USB1.1 what is the difference? Please do not worry, the following will be addressed. USB2.0 standard use Note: This article says Mbps but Philips jointly developed, published, standardized data transfer speed of the peripheral to 480Mbps, is 40 times faster than USB 1.1 devices! but as planned the new USB 2.0 standard is prepared to the standards set at 240Mbps, later, after efforts to It increased to 480Mbps. because at that time has changed the formulation of the standard, USB specification to have a choice of three speeds: 480Mbps, 12Mbps, 1.5Mbps. and June 2003, when the USB2.0 standard after the start gradually been taking root, USB Association Rename the USB specifications and standards, and perhaps the move was only a USB Association uniform standards in order to better Buzhi Yu confusion, but perhaps did not expect this standard USB Association of flash drives and MP3 market to create a chaotic situation. re-named USB standard will be changed to the original USB 1.1 USB 2.0 Full Speed (full version), while the original USB 2.0 into a USB 2.0 High-Speed (fast version), and also announced a new logo. It goes without saying Yu, high-speed version of USB 2.0 speed over full version of course USB 2.0. Although the current USB devices are widely used, but more generally it is USB1.1 interface, it is the transmission speed is only 12Mbps. For example, when USB1.1 scanner you scan an image size of 40M, you need half a minute ago. At this rate, so that users find it very inconvenient, if there is a good image to scan a few words, you have to have a good patience to wait. user demand is the driving force to promote technological development, manufacturers are also aware of this bottleneck. At this time, COMPAQ, Hewlett Packard, Intel, Lucent, Microsoft, NEC, and PHILIPS these seven companies jointly developed USB 2.0 interface standard. USB 2.0 data transfer between the devices increased rate of 480Mbps, faster than the USB 1.1 standard is about four times the speed increase is the greatest benefit for the users means that users can use to more efficient external devices, but also multi-speed peripherals can be connected to the USB 2.0 line, but also do not need to worry about data transfer bottleneck effect occurs. So, if you use USB 2.0 scanner to a totally different picture scanning only a 40M to be half a second or so, blink of an eye later, efficiency is greatly improved. It goes without saying, and now a lot of flash drives and MP3 market with the USB 2.0, USB1.1 is actually the original, and was named USB Association The USB2.0 Full Speed version. speed is only 12Mbps, 480Mbps high-speed version of the large gap. And, USB2.0 definition can use the same specifications as the original USB cable, connector specifications are also identical in the high-speed Like the premise of maintaining the outstanding features USB 1.1, and, USB 2.0 devices and USB 1.X device will not be shared when any conflict.

USB On-The-Go USB On-complementary standards The-Go Supplement 1.0:2001 released in December. USB On-The-Go Supplement 1.0a: 2003 年 6 month issued, the current version. USB OTG is the USB On-The-Go the acronym is the technology developed in recent years , December 18, 2001 published by the USB Implementers Forum, mainly used in a variety of devices or connection between mobile devices, for data exchange. In particular, PDA, mobile phones, consumer devices. changes, such as digital cameras, camcorders, printers and other equipment between the different standard connectors, up to 7 kinds of memory card formats for data exchange between the inconvenience. USB technology, making the PC and peripherals through a simple way, the manufacturing costs will moderate a variety of data transmission speed devices connected together, the above applications we mentioned, are available through USB bus, as a PC peripheral, under the control of the PC data exchange. However, this convenient exchange, once removed from the PC, the devices can not use USB port to operate, because there is no one from the same device can act as a PC Host. On-The-Go, the technology is realized in the absence of OTG Host circumstances, from a data transfer between devices. such as digital cameras connected directly to the printer , through OTG technology, connect the two devices see the USB port, will immediately print out photo shoot; also the data in a digital camera through the USB OTG interface sent to the mobile hard disk, there is no need to carry on field operations expensive memory card, or 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 adapt to the connection point to point; * This ability can dynamically switch between two devices; * Low power consumption, to ensure that USB can work under battery power after the use of OTG, does not affect the original equipment and PC's connection, but the market has made more than 1 billion USB interface device, but also through the OTG connectivity. [1] [2] [3] USB 3.0 About Intel Corporation (Intel) and industry-leading companies work together to set up USB 3.0 Promoter Group to develop 10 times faster than today's ultra-efficient USB interconnect technology. The technology was developed by Intel, and Hewlett-Packard (HP), NEC, NXP Semiconductors and Texas Instruments Incorporated (Texas Instruments) and other co-developed applications areas including personal computer, consumer and mobile products fast synchronous real-time transmission. With the growing popularity of digital media and increasing transfer files - even more than 25GB, fast Synchronous Instant transmission has become the necessary performance requirements. USB 3.0 Juyou backward compatibility standards, and techniques both traditional USB plug and play ease of use and functionality. the goal is the introduction of the technology than the current level of 10 times faster connection than the products, using the same architecture with wired USB. In addition to the USB 3.0 specification is optimized to achieve lower power consumption and higher efficiency than the agreements, USB 3.0 port and cable to achieve backward compatibility, and support the future of optical transmission. generation of the most popular means of personal computers wired Internet USB 3.0 can be a good solution to this challenge and continue to provide the user has used and continues to look forward to the USB ease of use experience. form. USB 3.0 Promoter Group, including HP, Intel, NEC, NXP Semiconductors and Texas Instruments, is committed to protecting existing USB device driver infrastructure and investment, USB appearance and ease of use features, while continuing to carry forward this great technology USB functions. Kissinger (Patrick Gelsinger) said, . higher rate of demand, thus shortening the waiting time for users. USB semiconductor solutions, as a leading provider, NXP is committed to promoting the standardization and high-speed USB applications. President Greg Hantak said, and compatibility to assist the development of USB devices, USB-IF has also vigorously promote the advantages of USB products by the quality of its certification. USB 3.0 standard was formally completed and published by the Intel, Microsoft, Hewlett-Packard, Texas Instruments, NEC, ST-NXP composed of industry giants such as 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. The new specification provides ten times the transmission speed of USB 2.0 and higher energy efficiency, can be widely for PC peripherals and consumer electronics products. worked out the USB 3.0 standard has been transferred to the specification of the management organization USB Implementers Forum (referred to as the USB-IF). The organization will work with hardware vendors to develop support for the new USB 3.0 standard hardware, but the actual product launch to wait for some time. USB 1.0 is the first edition appeared in 1996, the speed is only 1.5Mbps; two years after the upgrade to USB 1.1, but also greatly enhance the speed to 12Mbps,[link widoczny dla zalogowanych], so far in some of the old equipment can see this standard interface; April 2000, the widely used USB 2.0 launch speed of the 480Mbps, USB 1.1 is four times; now the first eight months later, USB 2.0 speed already can not meet the application needs, USB 3.0 will come into being, the maximum transmission bandwidth up to 5.0Gbps, which is 625MB / s, while the use of A-type backward compatible interface. IEEE organization has also recently approved a new specification IEEE1394-2008, However, the transmission speed of FireWire version only 3.2Gb / s, USB 3.0 is equivalent to little more than 60%. No wonder Apple and other industry players generally lost interest in this technology. USB 2.0 bus-based half-duplex two-wire system can only provide one-way data streaming, and USB 3.0 dual simplex using four-wire differential signal lines, and therefore support the two-way concurrent data stream transmission, which is the new standard rate of key reasons for the surge. In addition, USB 3.0 also introduces a new power supply management mechanisms to support standby, hibernate and pause status. measuring instrument maker Tektronix (Tektronix) first announced last month for the USB 3.0 test tool that can help developers to verify the new hardware design specification and between compatibility. USB 3.0 device application in practice will be referred to as expected to be launched in 2010. USB 3.0 marking graph
