<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}tools/extras/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. To start
developing with your device, also read <a href="{@docRoot}guide/developing/device.html">Using
Hardware Devices</a>.</p>

included with the <a href="{@docRoot}sdk/index.html">Android SDK</a>:</p>
<ol>
  <li>Launch the Android SDK Manager by double-clicking <code>SDK Manager.exe</code>,
  at the root of your SDK directory.</li>
  <li>Expand <em>Extras</em>.</li>
  <li>Check <strong>Google USB Driver package</strong> and click <strong>Install</strong>.</li>
