To use an attached USB device you need to have:. A USB OTG (USB On-The-Go) cable. USB Host Mode drivers loaded on your device. A version of the Android operating system loaded on that device that supports USB Host Mode. An Android device (eg phone or tablet) that has built-in hardware support for USB Host Mode.
And finally there need to be drivers on your device, for whatever USb device you're plugging in. Operating System USB Host Mode support was introduced in, so if you have Android 3.1, or newer installed on your device then you should have the necessary support for it in your OS, Android 4 also adds additional USB and OTG support. Also, many third-party ROMs add support for USB Host Mode to phones that have the hardware support, but don't have the necessary OS or driver support in the official operating system release. Host Mode Drivers Most devices that have both hardware support and a new enough OS will have the necessary drivers loaded to enable USB Host Mode, but some don't. You can find driver apps on the Play Store for some models that don't have built in drivers. Some models with 3rd party instructions and drivers available are:.
Cable You can't just use a normal USB cable. As these devices can act as both a USB 'slave' device (for instance so that you can plug them into a PC and copy music onto your phone, or copy pictures off the phone) and a USB 'host' (for example so that you can plug a USB memory stick into your tablet and copy files on or off it) they need some way to tell which they should act as at a given time. A USB OTG cable is what is used to tell your device to act as a host, this is like a normal USB cable but it has one of the internal pins connected to Ground at one end to let that device know that it should act as the host (technically pins 4 & 5 are shorted to ground in an OTG cable). Additionally, as most phones have micro-USB sockets, but most USB dongles have 'full-size' USB plugs, as below many OTG cables have a male micro-B USB plug at one end, and a female USB-A plug at the other to convert between the different sized connectors.

You may also find that your device's manufacturer sells an official, branded one, often called something like a 'Camera Connection Kit' or 'USB Memory Stick Connection Cable'. If you're brave you can also find various tutorials on the web on how to make your own OTG cable from a standard USB cable. USB device drivers When you plug your USB device into your Android phone or tablet it needs to know what that USB device is and what to do with it. For common devices, like USB memory sticks, or cameras that support PPTP or USB Mass Storage, these will often already be built into the OS. For other USB devices, like Wifi, 3G or Bluetooth dongles there may not be drivers pre-built into the OS, or only drivers for certain specific devices.
