<p>The Google USB driver is a downloadable component for the Android SDK, available
from the SDK Manager. The driver is for Windows only and provides the necessary drivers for the
following devices:</p>
  <ul>
    <li>ADP1 / T-Mobile G1*</li>
    <li>ADP2 / Google Ion / T-Mobile myTouch 3G*</li>
    <li>Verizon Droid*</li>
    <li>Nexus One</li>
    <li>Nexus S</li>
  </ul>
  <p>* <em>Or similar hardware on other carriers</em></p>
  
  <p>All other devices require Windows drivers provided by the hardware manufacturer, as listed in
the <a href="{@docRoot}sdk/oem-usb.html">OEM USB Drivers</a> document. The Galaxy Nexus
driver is also distributed by <a
href="http://www.samsung.com/us/support/downloads/verizon-wireless/SCH-I515MSAVZW">Samsung</a>
(listed as model SCH-I515).</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>The sections below provide instructions on how to download and install the Google USB Driver
for Windows. </p>

<p>The USB Driver for Windows is available for download as an optional SDK
component. You need the driver only if you are developing on Windows and 
want to connect an Android-powered device (ADP, Nexus One, or Nexus S) to your
development environment over USB. </p>

<p>To download the driver, use the Android SDK and AVD Manager tool that is
included with the <a href="{@docRoot}sdk/index.html">Android SDK</a>:</p>
<ol>
  <li>Launch the SDK and AVD Manager by double-clicking <code>SDK Manager.exe</code>,
  at the root of your SDK directory.</li>
  <li>Expand the <em>Third party Add-ons</em> and <em>Google Inc. add-ons</em>.</li>
  <li>Check <strong>Google Usb Driver package</strong> and click <strong>Install selected</strong>.</li>
  <li>Proceed to install the package. When done, the driver files are
downloaded into the <code>&lt;sdk&gt;\extras\google\usb_driver\</code> directory.</li>
</ol>



<h2 id="InstallingDriver">Installing the USB Driver</h2>

<p>Once you've downloaded your USB driver, follow the instructions below to install or upgrade the
