USB OTG

What is USB OTG

USB OTG is a hardware and software standard that allows you to connect a device to your smartphone or tablet through the USB Type-C or micro USB port. Almost anything that uses a USB connector can be plugged into your Android device with USB OTG, You would be able to control the second device using your smartphone, or  control your Android device using peripheral device.

 

Some good example uses for USB OTG include plugging a flash drive into your phone for extra storage, connecting your phone to a camera to serve as a viewfinder or shutter button, or simply plugging a mouse or keyboard into your tablet to get a desktop-like experience.

 

To accomplish this, you’ll need a special type of adapter called a USB OTG Cable(Adapter). They basically have one smaller end that plugs into your phone, with a larger end that you plug the second device into.

However, not all Android devices are compatible with USB OTG. So before you runing a USB OTG adapter, Please make sure your phone or tablet supports the standard.

 

 

 

What does OTG Feature Mean in Mobile Phones

USB On-the-Go devices, usually abbreviated as USB OTG, or referred to as OTG. It allow USB devices, such as mobile phone, as a host, allowing other USB devices, such as a mouse or keyboard, attached to them. Using USB OTG allows these devices to switch back and forth between hosts and clients.

Android’s open nature makes it easy to connect just about anything to it. If you want to use your tablet as a laptop, a keyboard and mouse is integral to the experience. You’ll be happy to know that Android works well with most wireless and wired keyboards and mice.

 

 

 

 

How to use OTG

To use USB OTG, the smart device must be other enabled (check manufacturer’s specifications to check whether your device is other compatible). USB OTG comes in many standards such as USB 2.0, USB 3.0 (superspeed USB OTG), USB type C etc. Type c is the fastest also the least used as phones with us type c are just beginning to be mainstream. Also for attaching mice or keyboard, the smart device and it’s OS both must support OTG.

 

 

 

 

 

 

 

 

 

What is The Difference Between USB On-The-Go (OTG) and USB Host Mode

USB Host Mode

USB has two different kinds of endpoint (connected device), like a client-server interface. One device is the computer-the host, and it’s in charge: it’s the server. All the other devices-the peripherals) are the clients, and can only communicate with the server.It wouldn’t make sense for a keyboard to be the host. That’s the way the protocol works, and the connectors are designed to make that easier for users: hosts have the rectangular A connector, and peripherals have either the square B connector or a mini- or micro- version.

Host mode is a name for when a device is acting as a host. Every USB connection has exactly one device in host mode. PCs always run in host mode.

 

 

 

 

 

 

USB OTG Mode

A phone is a bit different, though. Sometimes you want it to act as a peripheral: for example, so you can plug it into a PC, so the PC can access the phone’s storage. Sometimes you want it to act as a host: for example, to connect a physical keyboard or mouse to it. This is why many Android devices now support USB host mode as well as USB peripheral mode. But how can you make this work, when a host’s USB socket is different from a peripheral’s?

This is where OTG comes in. It adds an extra pin to the micro-USB socket. If you plug a normal A-to-B USB cable, the device acts in peripheral mode. If you connect a special USB-OTG cable, it has the pin connected at one end, and the device at that end acts in host mode.

This can be a little confusing if one cable has seemingly identical plugs at either end, which do different things. But cables with USB-OTG at both ends are uncommon: it’s more common to use an adaptor, which has a host-mode USB-OTG plug at one end, and a rectangular USB-A socket on the other. You can plug a normal USB cable into this adaptor, and it will work normally.

 

How to Connect USB Storage Devices to Your Android Phone

Many Android phones use micro USB ports for charging and transferring files back and forth with your PC, but what if the files you need to email your boss are sitting on a Flash drive or a full-size SD card?

Fortunately, with an inexpensive adapter cable, you can attach a USB key or card reader directly to your handset. Here’s how to connect your Android phone to a USB storage device. If you have a newer Android phone that uses USB Type-C, it’s even easier.

 

 

 

 

 

 

 

 

 

 

What About USB Type-C for Using OTG

Many newer Android devices uses USB Type-C for charging and data. If that’s the case with your device, you have it easy. You’ll need just one of the following items:

  • USB Type-C male to USB Type-A female adapter
  • USB Type-C flash drive

A USB Type-C OTG adapter will let you use your current flash drives. A USB Type-C flash drive, like this one, will fit directly into the phone without any dongles required. Then you just open your file manager and you’re good to go.
