When was usb 2 introduced

AB : We had organized ourselves to go attack all different aspects of a technology and what it takes to make it successful in the market because we wanted to cover all the bases. We not only wanted to do the spec, but we also wanted to help the developers develop products around this technology. Even though we were an alliance, we were like a startup who were paying attention to every aspect of not only the specs but the product development and ultimately, introduction in the market. JP: Ajay was the technical spec lead, Bala was the engineering lead, and I was running the overall program.

We were forming an engineering group. I asked Bala to join me running the program. He was looking into Intel and driving the engineering efforts, I was looking after driving the industry efforts. BC : Jim drove the external communication, the external alignment of industries, putting the promoter group together, the industry forum together. Often, he would defer to me to give keynote talks, but we tag teamed on that.

Routinely, Jim and I would touch base at the end of every day. It was an 11 p. That went on for years. That must be Jim. AB: I think we succeeded because everything that we did was well implemented. I knew that this would be the case because we had multidisciplinary teams where we had people who were experts in software and operating systems.

We had people who knew how to build systems, like IBM and Compaq. We had people who knew how to build chips, like Intel and NEC. We had Nortel that knew how to build the telephony and other things that eventually became very important. By assembling a team of experts, we were able to reduce the risk and see to it that these were very broadly applicable specs to a variety of applications. BC: Ajay was central to developing the spec itself.

He was also passionate in terms of understanding the requirements to make sure that the spec met the requirements. He felt strongly that this was something he wanted to work on.

He wrote a good chunk, I would say more than half, of the first spec along with all the white papers that went with it to develop the technology. AB: The spec got done somewhere in Thereafter, we started working on the products and stuff.

It was a long journey, but ultimately the industry realized that this was something that really addressed all the painpoints of a personal computer. Computer companies were eager to make plugging in easier, but one application on the horizon that seemed to demand a faster interface in particular was video. Digital multimedia was still in its infancy, but getting video on and off computers would become a major focus for comp uter and peripheral makers.

As Intel engineers worked on the interface that would become USB, they were also examining possibly faster alternatives. They would also have lower returns and fewer frustrated service calls. The Size of a 16 GB flash drive compared to a floppy disk.

We explored about 12 different technologies. When I first started attending those committee meetings to see whether that technology would work, was a megabyte interface. It felt like it was a technology looking for a problem to solve. It was also a little more complicated and expensive than what the PC cost point was. On the other hand, it had elements that would be potentially usable.

We looked at that generation of Ethernet-like technologies. We looked at audio interfaces. Apple had an interface called GeoPort back then. We actually talked to Apple to see if they might be interested in evolving that. Access Bus was another industry standard. AB: I personally went to so many different forums. I remember hosting a meeting with the key telephony vendors in Dallas, because there are a whole bunch of outside allies. We were trying to convince people that you could do computer telephony using something like USB, and a lot of people thought that we could not support certain things like that.

There was a view that HP had that your printers would talk to your computer using this link called infrared data [IRDA]. By then, there was a groundswell on USB. Back then, it was called the Serial Bus. So the question of naming goes three ways. It was too techy. That was a spec number. We tried coming up with consumer-ish names. Then we felt they were too far out from where USB was.

You turn to our organization, a lot of team names or organization names, project names, technology names, a lot of them are acronyms. That seemed to be a place for us to start with and the universality of the solution. We played around with that. How would we expand on that? Aside from media players, many other external devices use these data ports, including digital cameras, mobile phones, and newer cable boxes.

Native components also make use of this interface, such as mice, keyboards, and external hard drives, as well as printers and networking hardware. One of the most popular and convenient USB 2. In , USB 3. The 3. This USB standard has not been as widely adopted even though the standard was released in September Wireless USB uses frequencies in the band 3.

USB lead: Type A to Micro B connectors With the ever increasing requirements for faster and larger levels of data transfer as well as increased levels of convenience and capability, the concept for USB has evolved. The levels of functionality that are available today are enormous when compared to the first standard release in the late s.

Since then a number of new versions of the USB standard have been introduced, each providing a greater level of performance. The data transfer rates of USB 1. The data encoding method for this version of USB is Unicode.

Supplier Directory For everything from distribution to test equipment, components and more, our directory covers it. USB Universal Serial Bus is a universal connection used to connect electronic devices like digital cameras, external hard drives, printers, etc to a computer.

The idea was to replace all of the different connection types needed for different devices with one easy to use connector. We take for granted how much easier things are now that we have USB. For one thing, it was designed to work over all of the major operating systems. Back in the day you would have to restart your computer in order for it to recognize your device. There have been three different versions of USB released over the years, each one becoming increasingly faster.

Later USB 2. This was a huge step forward and allowed external hard drives and other mass storage devices to be used with USB. Every year people seem to have greater demands for transferring larger files at faster speeds. With the price of hard drives becoming more and more affordable, many at home now have external hard drives that are 1 terrabyte or larger. Not only that, but more people are now able to afford cameras that allow for high quality video and photos, making the files much larger.

You need faster transfer rates. SuperSpeed USB 3. Not only that, its bidirectional, letting you read and write data at the same time. What does that mean for you? It means you can download photos, music, videos, and data faster. But not just faster, ten times faster.

All of that added speed also means that USB Ethernet adaptors like the Gigaglider can now achieve internet speeds of up to 1 Gbps, making them even faster than wireless internet connections.

One more great thing about USB 3. These new capabilities allow for any unused devices you may have connected to your computer to enter into sleep mode, lowering your carbon footprint and your utility bills. If you have some USB 2. Just remember, if you want to achieve USB 3.

Some of the supported devices include external storage devices, USB 2. Brief History USB was originally designed to replace the motley assortment of cables coming out of the backs of personal computers with their big inconvenient connectors which were USB's predecessors: parallel and serial connections.

Future USB 3.
