This functionality is typically enabled through a special adapter cable, allowing a standard USB port to connect to the device’s micro-USB or USB-C port. The primary function of USB OTG is to enable direct communication between your Android device and other USB peripherals.
How to Connect and Use USB OTG Devices
Connecting and using USB OTG devices is usually a straightforward process. First, you’ll need a USB OTG adapter. This is a small cable or adapter that has a USB-A port (the standard USB port you see on most devices) on one end and a micro-USB or USB-C connector on the other, depending on your Android device. Simply plug the OTG adapter into your phone or tablet’s charging port, and then plug the USB device into the adapter.
Your device should recognize the connected device almost immediately. Sometimes, you may need to navigate to your device’s file manager to access the contents of a connected USB drive. It’s that simple!
Comparison of USB OTG with Standard USB Connections
The key difference between USB OTG and standard USB connections lies in the roles of the devices. With a standard USB connection to a computer, the computer acts as the host, and the phone acts as a device. USB OTG flips this around, with the phone or tablet becoming the host and controlling the connected USB device.
In a standard setup, the computer provides power and manages the data flow. USB OTG allows the phone to take on these roles, providing power (though often limited) and managing the data transfer.
