​How to connect flash drives, hard drives, keyboards and mice to the Samsung Galaxy S III using USB host

Here's a lesser-known feature of the new Galaxy S III -- the ability to connect all manner of USB peripherals to Samsung's latest flagship phone, from mass storage to input devices. You'll need a USB OTG (on-the-go) cable to be able to connect all this stuff into the Galaxy S III or any other USB host-supporting phone.

Like the Galaxy S II and Galaxy Note before it, the S III supports full USB host capabilities, meaning if you've got the right connector you can go completely nuts and plug all sorts of stuff into the phone. In our video, we tried USB memory sticks, full-sized SD card readers, USB hubs, hard drives, keyboards and mice. All of them worked. At one point we even had a hub plugged into the S III, allowing keyboard and mouse support simultaneously.

While we don't imagine many people will be using this feature every day, it's certainly impressive to see a smartphone able to handle such a wide range of USB gadgets, including full-sized desktop peripherals. Check out our video demo of USB host on the Samsung Galaxy S III above, and be sure to share your own experiences down in the comments if you've tinkered with this sort of thing yourself.
