USB 3.1 First and Second Generation

USB 3.1 First and Second Generation

Hi, fellows of Cyberspace, today I want to talk about USB 3.1 and several of its improvements, let us start.

In January 2013, the USB group revealed plans to upgrade USB 3.0 to 10 Gbit / s (yes you read it right). This led to the creation of a new terminal called, USB 3.1, or USB SuperSpeed was released on July 31, 2013.

But this was not so in the beginning since the first generation USB 3.1 ports have the same characteristics in speed that the USB 3.0 what changes are the introduction of the USB C-Type.

Now in the second generation, USB 3.1 SuperSpeed + these already have a vivacity of 10 Gbit / s

There is perfect compatibility between the first and second generation.

Update 07/08/2017

I was finally able to purchase a PCIe host adapter for the second generation USB 3.1 BIOS Type A.

Therefore, I have to work to test its speed.

I have tried it on two different computers, with very similar results

• Computer A: is an Intel I5 third generation, with a 3.1 GHz CPU and a 64-bit system with a 4GB RAM

• Computer B: is an Intel Core I7 CPU 2.30GHz 64 bit system with an 8GBy RAM

I will not deny that I have been disappointed a bit since I never reached the 10 Gbit / s I was between 7 and 8 Gbit / s.

USB 3.0

USB 3.0

Hi, fellows of Cyberspace, today I want to talk about USB 3.0 and several of its improvements, let us start.

In view of the fact that between 2004 and 2006 came the first external hard drives, allowing storage on Gigabyte and Terabyte, it was clear that USB 2.0 technology, which gave us a speed of 480 Mbit / s would soon be very slow, to This amount of data.

Therefore, in November of 2008 appears in the market the USB 3.0, with the main feature that is the multiplication by 10 of the transfer speed, which happens to be of 4.8 Gbit / s, to this new technology is called; USB 3.0 Super Speed. This is because now the cables allow working with five lines to send and two to receive, allowing bidirectional traffic.

It has also changed the current, which is now 900 milliamps, reducing the charging time of mobile devices.

These new ports have the intelligence rule, that if devices that are connected for a while and are inactive, they immediately go to a low power state.

At the end of 2009, manufacturers such as Asus or Gigabyte presented the basis of the forms with this new revision of the bus. The 3.0 version of this universal connector is 10 times faster than the previous one.

Now 3.0 ports have a light blue color to differentiate them from 2.0 ports

Where you can see a big change is in USB 3.0 Micro-B - The sidecar:

The only solution for USB 3.0 had a smaller connector. It was to take the existing Micro-B connector and stick another connector next to it. This appeared mostly on external hard drives, as they needed more current. The popular theory is that this format will be replaced very quickly by Type-C.

This connector is compatible with USB 1.x and 2.x always losing the advantages of USB 3.0

USB 2.x

USB 2.x

Hi fellows of Cyberspace, today I want to talk about USB 2.x and several of its improvements, let's start off

Well it has only been 6 years since the introduction of USB 1.x and we get USB 2.0 it was released in April 2000, which is already another level. It has a speed of 480 Mbit / s which is called High Speed or High Bandwidth.

The qualities and utilities of USB 2.0 will always be improved and will find new options for it  for the next 10 years, we will not stop having surprises, detail some of the most important for me.

In October of 2000, it seems the mini ports A and B, this also introduced the terminal for On-The-Go. That accepted both terminals.

In May of 2002, appear what for me is a good advance for this type of connection Pull-up / Pull-down ECN.

In May of 2003 we have ECN Interfaces that greatly improve communication between terminals, as it added a new standardized descriptor that allowed multiple interfaces to single device function.

In October 2003, we have Rounded Chamfer ECN, which was nothing more than making retroactive changes to the Mini-B connectors which results in much longer lasting connectors.

In March 2006, sees the Inter-Chip USB Supplement something that was very useful for mobile technology.

In December of 2006, we said goodbye to the host for USB, thanks to the supplement On-The-Go 1.3

Nevertheless, it was in April 2007 that introduced battery charging technology 1.1 that allowed a USB host that can act as chargers

In addition, this April brought us the cables and connectors Micro USB 1.01

In July of the same year, we saw as the dream came to USB ports. Devices in this state did not reduce power consumption. However, switching between enabled and idle states is much faster than switching between enabled and suspended states, allowing devices to sleep while idle.

USB 1.x

USB 1.0 and 1.1

Hello fellow of Cyberspace, today I want to talk about USB 1.x let is start

Well for this we going to make a trip in time, to the last millennium and century to be precise the decade of 90. It is invented a new term USB, abbreviation of Universal Serial Bus, is one of the many initiatives of the time to standardize the ports that interact between computers and a whole range of peripherals and electronic devices. For example keyboards, digital cameras, printers, and a large etc. USB has supplanted a wide range of previous interfaces, such as serial ports and parallel ports, as well as separate power chargers for portable devices.

After this introduction we will see the specifications

Previous versions have been on the market sins 1990, but the change was not introduce until 1996 and was a USB 1.0 had a data rate of 1.5 Mbit / s and had two types of terminal that was A that is the famous rectangle and the B some kind of square. Due to its low speed it did not allow extensions or other modifications very few

However, in 1998 came the USB 1.1 that introduced the speed of 12 Mbit / s now this one was very well received, we can see the change in the printers or also the appearance of Legacy-free PC of Microsoft

Even though this may seem strange to us, but not many attempts were made to make smaller connectors there were a couple of attempts with type B but it was not specific and gave connection problems.
