What’s Moto G USB OTG?
Normally USB uses a master/slave architecture. A host acts as a master device for the connection, the other USB device acts as a slave.
Devices are designed to assume one role only. For example, when you connect an external disk to the PC, the PC is always the host, and the external disk is always the slave. When you connect two external drives through USB, nothing happens.
For Moto G, like many other phones, when it is connected to PC, it will be acted as a slave and be mounted as a storage device. You can access the file on the Moto G from your PC.
But what happens if you connect a USB thumb drive to Moto G?
Moto G can mount it as external storage, and you can use it just like you use an external drive on a PC!
Because Moto G supports USB OTG.
Of course, there are some other requirements to make it work.
We will discuss them later.
How Moto G USB OTG can help Moto G owners?
So, basically, Moto G USB OTG makes it possible for you to use external USB devices on Moto G.
Storage is just an example. The miserable storage in Moto G usually is the motivation for some owners to find ways to expand the storage.
You can also hook many other USB accessories, e.g., even a USB keyboard or mouse.
In this guide, we will focus on storage because it is the most wanted Moto G USB OTG usage.
Also, this guide applies to Moto X and many other Android devices, although Moto G is used.
What do you need to use Moto G USB OTG to expand your storage?
To use Moto G USB OTG to expand your storage, you need one of them:
- a USB OTG adapter (less than $10). One end of the USB OTG adapter connects to USB storage, which can be a normal thumb drive or even a portable hard disk. The other end connects to Moto G directly.
- or, an USB OTG flash drive (price depending on the capacity. It is slightly more expensive than normal USB thumb drives with similar capacity.). Such drives usually have two USB interfaces. One large female interface allows it to be used as a normal USB thumb drive on PCs and laptops. The male micro USB interface (OTG micro plug) allows you to insert the drive into Moto G directly.
So, if you want to use your existing thumb drives or portable disk, you can invest a few dollars to get an OTG adapter. The adapter can also be used for other USB devices.
If you are considering getting a new thumb drive, it is time to consider a USB OTG flash drive. It will be slightly more expensive than a normal thumb drive with a similar capacity. But you can use it on both phones and PCs without any adapters.
