Happy 20th Birthday USB! from Nov.15 1995 to Nov.15 2015

The father of the USB, Ajay Bhatt told us the story of usb’s birth.

Ajay Bhatt

Ajay Bhatt, from wikipedia, Ajay V. Bhatt is an Indian-American computer architect who helped define and develop several widely used technologies, including USB, AGP, PCI Express, Platform Power management architecture and various chipset improvements. And he is an Intel fellow.

Ajay Bhatt told the media about all of the story of the invertion of USB.“Anytime (my family) wanted to do something simple like print a letter for my daughter’s school, I would get a phone call from my wife that she just can’t print it,” Bhatt said. “She does something, but nothing happens to the printer.” It is a humble story.

And during the interview Ajay Bhatt told us why why it didn’t have a reversible connector.”We wanted to solve the problem with four pins and very few gates on our silicon and also four wires,” Bhatt said. “To make things flippable you need twice as many wires, that means twice the cost, and you need a lot more circuits. We could have done it but the cost of this would not have been acceptable to people.”

What is USB Type-C and Why We are Excited About It
Thursday, August 20th, 2015 | Author: Elaine

USB Type-C is an USB interface(connector) defined by USB Implementers Forum, Inc., creators of USB technology. Welcome to USB Type-C! Apple’s new MacBook has implemented the USB Type-C port, which will be the future modern product of USB Port.

USB Type-C Features

USB Type-C Features

From the shape, USB type C is greatly different from the common USB Type A. Although the USB technology has developed from the USB 2.0 to USB 3.0, and USB 3.1, the appearance of the port we mostly use is USB Type A, which has a right and wrong side when you plug it in.

With the newly designed USB type C, you needn’t worry about reversing the usb cable when plugging it in.

Let’s first get an overview of USB type C, except this easy plug feature.

  1. USB Type-C is a specification for a reversible-plug connector for USB devices and USB cabling.
  2. Rather slimmer and thinner than USB type-A.
  3. typeA and type C

    USB Type-A (Left) and USB Type-C(Right)

    As the following picture shows, the right side USB type-c is much smaller and thinner than the left USB Type-A. A Type-C port measure is just 8.4mm by 2.6mm. This means it’s small enough to work for even the future smallest peripheral devices.

  4. USB type C is USB 3.1 standard. High Speed as 10M bps and as a power port. 2X  Transferring speed of the USB 3.0.
  5. The USB-C connector supports DisplayPort, HDMI, power, USB, and VGA. Notably absent is Thunderbolt.
  6. USB Type-C is backward compatible but requires adapters. It’s fully compatible electrically with USB 3.0, though obviously it won’t plug in physically without an adapter. It is fresh that USB needs an adapter.
  7. Power Supports:

Indications are that the USB-C standard supports at least 100 watts of power delivery, so it’s possible that USB-C could replace most power adapters as a standard in the future. Using USB to power a laptop isn’t new, though. Look at the Lenovo Yoga 3 Pro $1,299.00 at Lenovo, which has a full-size USB 3.0 power connector.

Look at the connector interface of USB type-C.

Are there any latest USB Type-C applications in consumer products?

Yes. There are booming. Besides the Apple MacBook port, there are more and more USB Type c products emerge.

Watch this Video about USB type-c by expert of PCmag:

https://www.youtube.com/watch?v=G7d_17o0KsQ

I have collect some USB Type C products in the latest days:

  • Lattice Semiconductor Expands USB Type-C Product Family
  • Asus Releases ZenPad Flagship With USB Type-C
  • Google Nexus 5 2015 Release Update: Fingerprint Sensor, USB Type C

For Adapters:

The majority of USB type-c adapters are the USB Type-C to USB Type-A adapters.

USB type-c to USB 2.0 adapters for power

USB type-C to USB 2.0 female cable

USB Type-C to Mini USB data power adapter

Apple USB Type-C to USB Adapters.

Thought we need adapters to transferring data between USB Type C and common USB products. It is not long before we do not need adapters when the USB Type-C becomes more popular.

USB Implementers Forum, which is the creator of USB Type-C, says that Type-C USB is designed to be future-proof. In the future, there will be more and more USB Type-C devices for the fastest USB connectors. When USB Type-C becomes as popular as the current USB Type-A, it will be easier when we working with devices. We will hold tiny USB devices for both data and power connections. Just welcome the smart digital connection and cables of USB Type-c of USB 3.1

The history of USB and other portable storage

USB Flash Drive Alive Models
Thursday, January 10th, 2013 | Author: Elaine

There is little doubt that USB Flash Drives became a big a part of everyday people’s life. we have a tendency to use them everyplace just in case there’s a desire to manage any reasonably data. So, it’s quite perceivable proven fact that folks pay additional and additional attention to the planning of such devices. Considering the actual fact that everyone has them, we have a tendency to perceive that the sole thanks to vary is to own one thing really extraordinary.

This uncommonness will show itself in several ways that, such as: colours, forms, sturdiness etc. As regards given device the sole feature that distinguishes it from alternative counterparts is its ability to vary physical look. Thus, if you purchase this device it’ll seem like terribly straightforward one. However, once you penetrate and start operating with the device, repetition plenty of files thereto, you’ll conclude that your flash drive becomes larger and greater. just in case you delete files from you device, you’ll observe simply reverse impact. As way as alternative characteristics area unit involved it ought to be mentioned that {they area unit|they’re} quite usual ones: average speed and capability (there are simply 3 sorts – 512MB, 1GB and 2GB).So, i feel its “abilities” will not pass unnoticed obviously. Yet, some folks might imagine that only one distinction isn’t enough for a factor to be thought of as a special one.

Official Tool Enables USB Install for Windows 7
Friday, October 30th, 2009 | Author: Grace

official_windows_7_usb_key_tool_news

Microsoft has finally owned up to the exciting new tool it’s releasing with Windows 7, a bootable USB Installer creator. Aimed squarely at netbook owners, which have eschewed the venerable optical drive for weight and battery life. Microsoft’s tool will let you take your downloaded install files and turn a sufficiently sized USB drive into a bootable installer. Be prepared, if you’ve never tried to put a few gigabytes of files onto an average flash drive in one sitting, you’re probably in for a bit of a wait. A USB hard drive is probably a better bet but not as cool. The program may also be called Windows 7 USB/DVD Download Tool.
Microsoft’s site describes the process as downloading the installer directly to the USB drive. We’ll have to wait for a few people to report back to find out exactly how it works. Having the option will definitely help netbook owners as well as system administrators. Being able to do away with CDs and DVDs for installs would definitely make support installs and server installs go a lot faster. It’s available now at Microsoft’s online store for download and purchase.
