An inexpensive USB On-The-Go adapter is all you need to connect keyboards, USB hard drives and gaming controllers to your Android tablet. It is essentially a female USB port plugging into tablet Micro-USB ports for connection to standard USB 2.0 or 3.0 devices. It allows the Android tablet to become a USB host for the powering and communicating with the connected device.
The USB On-The-Go adapter is compatible the Samsung Galaxy S II (S2) and S III (S3), Galaxy Nexus, Nexus 7, Droid RAZR, Samsung Galaxy Tab, Acer Iconia Tab A200 and A500, Archos G9, Notion Ink Adam, Motorola Xoom, Toshiba Excite 10 and Sony Tablet S.
A quick notification appears when the USB OTG adapter is connected to an Android tablet that lets it known that the tablet is recognizable to the adapter and that it is ready to become a USB host. A number of USB devices can then be plugged in, such a USB thumb drive, a Desktop keyboard, a mouse, a USB hub, a powered hard drive, a PS3 controller, a card reader, a DSLR camera and a USB-to-Ethernet adapter.
The Android tablet will quickly display the contents of the plugged in USB thumb drive. The interface plays movies and music as well as views photos and documents. It allows the movement and copy of files from the thumb drive to the tablet’s SD card, proven to be the most practical use of the USB OTG adapter that is an excellent way to transfer files quickly or to expand the storage of your tablet. The ES File Explorer app can be resorted to should your tablet be unable to recognize the USB thumb drive despite the use of the USB OTG adapter.
The connection of a wired or wireless standard computer keyboard to your Android tablet via the USB OTG adapter will enable long-form writing, where shortcuts like Ctrl-A and Ctrl-X work.
