<p>The USB driver for Windows is a downloadable component for the
Android SDK. If you are developing on Windows and would like to
connect an Android-powered device to test your applications, then you will need
to install the USB driver.</p>

<p>This document provides information about the latest version of the
USB driver and a guide to installing the driver on your development
computer.</p>

<p class="note"><strong>Note:</strong>
If you're developing on Mac OS X or Linux, then you do not need to install a
USB driver. Refer to <a
href="{@docRoot}guide/developing/device.html#setting-up">Setting up a
Device</a> to start development with a device.</p>

<p>Before you perform the installation below, you must have the USB
driver saved to your development computer. To get the USB driver, use
the AVD and SDK Manager included with the SDK Tools to download the USB driver
as an SDK component. For more information, read <a
href="adding-components.html">Adding SDK Components</a>.</p>

<p>Once you have the USB driver saved to your computer, select the
appropriate procedure below, based on your operating system and whether you're
installing for the first time or upgrading.</p>

<p>If you are connecting an Android-powered
device to your computer for the first time, follow the below procedure to
"Perform a fresh installation." If you have installed one of the older
USB drivers and would like to upgrade to the latest version, follow the
procedure to "Upgrade an existing driver."</p>

<p>Once you've completed the USB driver installation,
please see <a
href="{@docRoot}guide/developing/device.html">Developing on a Device</a> for
other important information about using an Android-powered device for
development.</p>
