Google USB Driver

The Google USB driver is a downloadable component for Windows developers, available for download from the AVD and SDK Manager.

The Google USB Driver is only for Android Developer Phones (ADP), Nexus One, and Nexus S. If you're using a different Android-powered device, then you need to get a USB driver from the device OEM. For help finding the appropriate driver, see the list of OEM USB Drivers.

Note: If you're developing on Mac OS X or Linux, then you do not need to install a USB driver. Refer to Setting up a Device to start development with a device.
