How do I install the USB driver for Nexus One on Windows 7 for debugging purposes?

Question

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".

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?

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.

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.
