I have implemented a simple Android application that I now would like to test on a real device. I have a Nexus One.

In the Android Eclipse plugin, I have downloaded and installed the USB driver (revision 3) package. But when I connect my Nexus One to my PC (running Windows 7) using the USB cable, a message box pops up and shows that "No driver found" for "Nexus One".

Driver Software Installation

I have activated USB Debugging on my device. And when I run adb devices on my PC, it just prints List of devices attached and no devices are listed. And if I use Device Manages in Windows, and tries to update the driver for "Nexus One", I can not select a driver in the "driver directory" of Android SDK.

How can I install a driver for Nexus One on Windows 7 so I can use it for USB debugging my Android applications on a real device? Android SDK and AVD Manager Device Manager

  • If you have already installed the adb drivers for another android phone you can go through the advanced driver settings and make it use the existing installation – Nathan Schwermann Nov 05 '10 at 00:33

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.

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

USB Driver for Windows, Revision 3 (January 2010)
Adds support for the Nexus One.

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 to your development environment over USB.

To install the driver or upgrade your existing driver to the latest revision, you must first download the driver to your development computer.

To download the driver, use the Android SDK and AVD Manager tool that is included with the Android SDK. If you haven't yet installed the Android SDK, as described in Installing the Android SDK, please do so before continuing with the driver installation.

When you are ready to download the driver, follow the instructions given in Adding SDK Components to launch the Android SDK and AVD Manager. From the Available Packages panel, select "Usb Driver Package" and download it to your computer. The driver files are downloaded into the <sdk>\usb_driver directory.

After the download, follow the instructions below to install or upgrade the driver, based on your needs and Windows operating system version. 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."

Once you've completed the USB driver installation, please see Developing on a Device for other important information about using an Android-powered device for development.

  • My installation did not automatically find the device drivers. I had to go into device driver and manually tell it to search for a device driver in this folder: c:/program files/Android/android-sdk/extras/google/usb-driver/ – Orbiting Eden Aug 02 '12 at 23:21

    Note that this answer is [no longer correct](http://stackoverflow.com/a/6498538/1269037). The USB drivers are no longer in the `extras` directory of the SDK. – Dan Dascalescu Mar 26 '13 at 05:00
  • They're currently in `C:\Users\\AppData\Local\Android\sdk\extras\google\usb_driver`. – ban-geoengineering Apr 12 '17 at 10:48

As of March 2013, you don't need to install any Nexus One driver - Windows 7 is able to install the driver online automatically if you allow it. The driver will be named Android Composite ADB Interface:

Android Composite ADB Interface

Just make sure to let Windows install drivers from Windows Update: type "Change device installation settings" in the Start search field and check "Install driver software from Windows Update if it is not found on my computer.":

enter image description here

Why do this? Because you don't have to install the entire Android SDK, or the ~400MB ADT Bundle, which (by the way) no longer has the driver files in the \extras\google\usb_driver\ directory, despite Google's claim.

Go to Settings -> Applications -> Development and check that USB Debugging enabled.

better use a sync product like Dropbox or Fiabee, you'll be able to transfer anything back and forth with no effort, works with all USB cables :) In the second, you can even synchronize your photos without having to worry about copying them.
