However, it may cost much money when the system updates into a higher level. In fact, mobile phone itself is equipped with a function that will save its insufficient memory, namely the USB On-The-Go function.
Your smartphone can achieve data transmission while connecting to many devices, which greatly facilitates our daily life. So let us know more about the USB On-The-Go function.
What is USB On-The-Go?
USB OTG or OTG is the abbreviation of USB On-The-Go. Products with this feature allow devices, which act as the host, connect to other peripheral devices to achieve data transmission. Previously, the cell phone without no OTG function was used as a USB peripheral to transfer data with the computer. It also can not be connected to the printer, because it is the same with the cell phones as A USB accessory. But now OTG function directly address this issue.
Standard USB adopts a master/slave architecture. Host-peripheral role swapping can be achieved between devices, which means that the roles of the same device can be different. Whether it is a USB host or USB device totally depends on which end of the OTG cable it connects to. For example, a USB printer usually acts as a slave device. But if you plug a flash drive including images into the printer’s USB port without a computer, that will allow the printer to act as a host to read the data from the flash drive and print images from it with the help of OTG function.
Of course, USB OTG can also be realized while the USB hub is used. But host-peripheral role swapping is only available when two OTG devices are directly connected (one-to-one connection).
Let us take the cell phone as an example, OTG function permits cell phones and tablets to connect to flash drive, card reader, digital camera, keyboard, printer and even the mouse, which is totally plug-and-play.
