What Is USB OTG on the Go?

USB communication is established between a host(PC for example) and a slave (USB Keyboard or Flash memory).

OTG is a technology that enables you to use USB devices without a PC as a host. That's because OTG devices can work both as a master or a slave USB device.

You can find this feature on devices like Smartphones, Cameras, etc.

Xiaomi 5a Smartphone supports OTG technology and hence can be used a slave USB device connected to the PC. And it can also act a host when connected to other USB slave devices( USB Flash Memory, Cameras, Keyboard, Mouse)

Here is what I used

USB OTG (On The Go) Cable banggood , Amazon US , Amazon UK , Amazon CA , Amazon DE , Amazon FR , eBay , souq

USB Flash Memory (Used independently as a side experiment) banggood , Amazon US , Amazon UK , Amazon CA , Amazon DE , Amazon FR , eBay , souq

Connect the USB OTG cable to the phone and then connect the USB Flash Memory.

You can see that The USB Flash Memory is powered from the phone.

Open the file explorer built-in application.

You can see the USB Tab on the application indicating the USB Flash memory with its contents.

Then switch to another tab on the files explorer. Remove the USB Flash Memory.

Connect the USB Keyboard to the OTG Cable.

Note that popup indicating a physical USB keyboard connected to the phone.

Open word editor. I used Microsoft Word installed on the phone.
