Google USB Driver




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:

• ADP1 / T-Mobile G1*
• ADP2 / Google Ion / T-Mobile myTouch 3G*
• Verizon Droid*

• Nexus S

* Or similar hardware on other carriers
All other devices require Windows drivers provided by the hardware manufacturer, as listed in the OEM USB Drivers document. The Galaxy Nexus driver is also distributed by Samsung (listed as model SCH-I515).
Note: 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 Using Hardware Devices.

To download the driver, use the Android SDK Manager tool that is included with the Android SDK:

1. Launch the Android SDK Manager by double-clicking SDK Manager.exe, at the root of your SDK directory.
2. Expand Extras.
3. Check Google USB Driver package and click Install.

OEM USB Drivers

If you are developing on Windows and would like to connect an Android-powered device to test your applications, then you need to install the appropriate USB driver. This document provides links to the web sites for several original equipment manufacturers (OEMs), where you can download the appropriate USB driver for your device. However, this list is not exhaustive for all available Android-powered devices.
If you're developing on Mac OS X or Linux, then you probably don't need to install a USB driver. To start developing with your device, read Using Hardware Devices.
Note: If your device is one of the Android Developer Phones (ADP), a Nexus One, or a Nexus S, then you need the Google USB Driver, instead of an OEM driver. The Galaxy Nexus driver, however, is distributed by Samsung (listed as model SCH-I515).
