Here Are The Amazing Facts About The USB OTG

One of the features that I would love to bring Android factory is precisely the OTG. But of course, What is OTG? How do I use it ? Can you give me my little droid this functionality? In the following article, I hope to thresh all these questions as far as possible. And, of course, with the fewest possible technical terms, so that everyone can understand and enjoy as well such a productive feature.

1. What is OTG?

OTG or USB OTG (On-The-Go), is an extension of USB 2.0 that allows devices with USB ports more flexibility in managing that connection. Or what is the same (and talking fast and wrong), you can connect any USB device using our smartphone or tablet. Whether a digital camera, a flash drive, a USB modem, a keyboard, a mouse, etc. This is based on our terminal goes from being a mere slave, to behest. Which enables us to access other devices as master. The most graphic example would be to connect a flash drive. We can access the information it contains simply connecting it to your smartphone.Mola, right?

Imagine the possibilities open to us. Being able to connect your smartphone to a hard drive and have all the movies and music you want instantly. The connection to our DSLR and use our terminal as Interval meter or storage device and instant editing. There is a very wide range of options we can explore by ourselves.

2. How do I use it?

Of course, not everything is rosy light. Our androids carry a micro USB connector and implemented most computers that access will require a USB. That is why we need a cable like the image below. AB OTG USB cable that allows us to connect the port a (micro USB male) with B (female USB) port. These cables are not expensive. In fact, if you dig a little network, we can find a huge variety in prices and lengths.

The USB On the Go is facile to use, since it is simply plug and play. But, as I said before, not all light and color. And it is that almost all devices need power to operate. And of course, if your terminal does not bring factory OTG support (like my GalaxyS), it is normal to connect, and even with the kernel flasheado not work us. This happens because the micro USB port terminal emits no electricity, since it is a slave. Almost all electronic devices operate by receiving 5V (volts), which is what usually give a common USB port. If you do not have USB OTG factory, our port will not give us the necessary voltage to operate the flash drive or hard drive. And OTG Card Reader for All Devices are available.

But we do not give up. For everything there is solution. And it is that connecting an external power supply, and thanks to a HUB USB (or USB cable Y), we can use the OTG "a pleasure". In the picture above we can see a diagram that explains all this quite well.

3. Can you give me my little droid this functionality?

Perhaps this is the bitterest part of the article, because not all androids support this extension. And unfortunately there is no "official list" we can give so that everyone can see if your device is on it. There are more Android colors, so it is very difficult to establish that list. The best way to know if your terminal supports USB OTG, is entering the specialized forums (XDA, Android Central, HTC Mania, etc.) and look in the section if a developer has a kernel that can flash to enable or this functionality, if the phone supports factory, see how to enable it to take advantage. Sometimes it serves, sometimes it takes root, sometimes you need to flash a kernel ... is a lottery.
