I had a similar sounding situation with my Nexus 4. For me it was an issue with the drivers Windows was installing automatically. I followed the instructions in <a href="http://forum.xda-developers.com/showpost.php?p=34658752&amp;postcount=8" rel="nofollow">[Q]Computer won't recognize phone? - Post #8</a>. I had some slight differences on Windows&nbsp;7.

For me I,

<ol>
<li>Uninstalled the driver from Device Manager</li>
<li>Let it automatically install the generic 'MTP device driver'</li>
<li>Right clicked on the new device and selected 'Update Driver'</li>
<li>Selected 'Have Disk' and pointed it to [android-sdk-dir]\extras\google</li>
<li>Watched an 'ADB' driver install.</li>
<li>Opened Eclipse to successfully run on my Nexus 4.</li>
</ol>

Good luck!

I had to resort to a clean install of Windows&nbsp;7 x64 to fix this issue.

I tried all steps/variants in the other answers. No luck. Device Manager would show my 'Android Device / Android Composite ADB Interface' working properly with the 7.0.0.1 driver from Google, but nothing could get 'adb devices' to show my Nexus 4.

I used <a href="http://www.nirsoft.net/utils/usb_devices_view.html" rel="nofollow">USBDeview</a> to uninstall every USB device that had connected to my computer except my keyboard and mouse. No luck.

I enabled 'Show hidden devices' in Device Manager and uninstalled anything related to USB. No luck.

I added Google's vendor ID to adb_usb.ini. No luck. I deleted adb_usb.ini and ran 'android update adb'. No luck.

I brought my Nexus 4 to my brother's apartment to confirm it wasn't faulty. Worked on his machine without a hiccup.

I'm glad the clean install worked, because further troubleshooting was going to require swapping motherboards or buying a MacBook.

Boy, that escalated quickly.

How to do it on Windows 8 (I think, it will work for Windows 7 too)

<ol>
<li>Open Android SDK Manager and delete Google Usb Driver</li>
<li>Open Control Panel -> Devices Manager -> Find your Nexus -> right click -> delete device</li>
<li>Unplug your device</li>
<li>Open Android SDK Manager and install Google Usb Driver</li>
<li>Connect your device</li>
<li>Open Control Panel -> Devices Manager -> Find your Nexus -> right click -> update drivers -> Manual update -> open android-sdk folder (enable checkbox for subfolders) -> install driver from Google Inc</li>
<li>adb kill-server; adb start-server; adb devices should show your nexus</li>
</ol>

Do not forget, that Android 4.2 now want you to submit RSA key from your computer, look at your device screen.

To enable developers options on Android 4.2: Open Settings -> About phone -> Tap on Build Number 7 times.

Just to add to the above posts for anybody struggling to get their Nexus 4 recognized by Eclipse - ADT. In the past the device was recognized by Eclipse ADT without any issues!

I ran into the same problems as the original question. Every approach I tried wouldn't work...

<ul>
<li>Toggling "USB debug" selection</li>
<li>Toggling "Allow 3rd party" apps selection</li>
<li>Allowing Mock locations</li>
<li>Reinstalling driver</li>
<li>Restarting adb.exe</li>
</ul>

Simple solution in the end

<ul>
<li>Go to Settings -> Storage -> USB Computer Condition (Menu option from Storage Screen)</li>
<li>Change from Media Device (MTP) to Camera (PTP)</li>
</ul>

In case none of the answers work perhaps the following clarifications will help.

Once enabling PTP mode the ADB devices command would find my Nexus 4, but I could not push to it. I had to use <a href="http://en.wikipedia.org/wiki/Eclipse_%28software%29" rel="nofollow">Eclipse</a> and in order for the dialog to display to accept the RSA key described below.

You need to install USB drivers only if you use Windows (If you're using MAC/Linux, most likely it will work fine without any driver installations)

in the following link they describe how to do it: 

<a href="http://developer.android.com/tools/extras/oem-usb.html" rel="nofollow">http://developer.android.com/tools/extras/oem-usb.html</a>

In short: 

<ol>
<li>Connect your Android-powered device to your computer's USB port.</li>
<li>Right-click on Computer from your desktop or Windows Explorer, and select Manage.</li>
<li>Select Devices in the left pane.</li>
<li>Locate and expand Other device in the right pane.</li>
<li>Right-click the device name (such as Nexus S) and select Update Driver Software. This will launch 6. the Hardware Update Wizard.</li>
<li>Select Browse my computer for driver software and click Next.
Click Browse and locate the USB driver folder. (The Google USB Driver is located in \extras\google\usb_driver.)</li>
<li>Click Next to install the driver.</li>
</ol>

I have 2 Nexus 4 devices. One was connecting to ADB without any problems, the second one never showed up when I used the <code>adb devices</code> command. An additional symptom was, that the second phone did not show up as a portable device in Windows Explorer when the phone was set to Media mode.

At some point I found that a temporary solution for the second Nexus was to switch it to PTP mode. Then it was found by the <code>adb devices</code> command. The weired thing was that the first phone worked in both modes all the time!

Finally I found this solution that now allows me to connect both phones in both modes:

<ul>
<li>set USB mode of the phone to MTP (Media) 
Using PC device manager uninstall the device ->Android Device ->Android ADB Interface 
Make sure to check the box "Delete the driver software"!</li>
<li>then set the USB mode of the phone to PTP (Camera) 
Using PC device manager uninstall the device ->Portable Devies ->Nexus 4</li>
<li>Then unplug the USB and plug it back in (ensuring that its set to MTP (Media) and I found that the device was correctly registered in Device manager as a ->Portable Devies ->Nexus 4</li>
</ul>

Solution found at: <a href="http://forum.xda-developers.com/showthread.php?p=34910298#post34910298" rel="nofollow">http://forum.xda-developers.com/showthread.php?p=34910298#post34910298</a>

If you have a similar problem to connect your Nexus to ADB then I recommend to first switch it to PTP mode. If your problem vanishes with that step, I recommend to go through the additional steps listed above as MTP will probably be the mode you will want to set your phone to most of the time.

I had a similar problem, and none of the previous solutions worked for me, and I've just solved it by myself (after a few hours of frustration), so I'm going to share my solution.

My computer suddenly stopped recognizing any Android device I've plugged in after it installed Android Composite ADB Interface for my Nexus 4. I was not able to uninstall the driver, because any attempt to do so by Device Manager was unsuccessful (Device Manager stopped responding every time).

So I've solved it this way:

<ol>
<li>Switch Windows into safe mode</li>
<li>Uninstall Android Composite ADB Interface</li>
<li>Install old SAMSUNG Android ADB Interface</li>
<li>Switch Windows into normal mode</li>
<li>Plug-in Android device (Nexus 4 in my case)</li>
<li>Windows recognized the device as Nexus 4</li>
<li>Install driver from android-sdk/extras/google folder</li>
<li>Everything works again! :)</li>
</ol>

It was a driver missing problem with me. I had enabled the USB debugging, tried changing the USB cable, tried reinstalling the Google USB drivers, but nothing came to my rescue.

Then ultimately I downloaded the device drivers as suggested <a href="http://www.android.gs/how-to-install-google-nexus-4-usb-drivers-for-adb-sideload-support/" rel="nofollow noreferrer">here</a>.

To make sure whether you have a device driver problem, go to:

<ol>
<li>Computer->right click</li>
<li>Manage</li>
<li>Device Manager</li>
</ol>

And see if you have your Nexus shown as an "Android device" or as a device in "Others".

If it shows in "Others", your problem should be resolved by downloading &amp; extracting <a href="http://www.mediafire.com/download/sc1ljof749qlayq/usb_driver.rar" rel="nofollow noreferrer">this</a> and then following these steps:

<ol>
<li>Right click on your device after finding it in Device Manager as per the above mentioned three steps.</li>
<li>Say Update driver software.</li>
<li>Say Browse My computer for driver software</li>
<li>Pinpoint it to the location where you had downloaded the drivers from the above link.</li>
</ol>

Finally, your device will show up as follows:

As soon as you do this, a popup will show up on your device asking for permission to debug. Once you accept, you are ready!

I'm running on Windows 7, and I've updated all the drivers as it says on the Android developer website regarding using hardware devices. However, <a href="http://en.wikipedia.org/wiki/Eclipse_%28software%29" rel="noreferrer">Eclipse</a> is still not recognising my Nexus 4 when I try to run the application. The Android device chooser pops up, but it doesn't show anything on the hardware section. I've turned debugging, third-party apps, and mock locations all on on my phone as well.

Is this because the phone is still new? Is there a way of making my Nexus work with Eclipse?

Nothing is showing up under <a href="http://en.wikipedia.org/wiki/Android_Debug_Bridge" rel="noreferrer">ADB</a> devices in the command prompt.

我在Windows7上运行，并且我已经更新了Android开发者网站上关于使用硬件设备的所有驱动程序。然而，当我尝试运行应用程序时，仍然无法识别我的Nexus4。Android设备选择器弹出，但在硬件部分没有显示任何内容。我还在手机上打开了调试、第三方应用程序和模拟位置。这是因为手机还是新的吗？有没有办法让我的Nexus与Eclipse协同工作？在命令提示符下，设备下未显示任何内容。
