ADB not recognising Nexus 4 under Windows 7

Question

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, Eclipse is still not reco

Answer 1

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 here.

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

1. Computer->right click
2. Manage
3. Device Manager

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 & extracting this and then following these steps:

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

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 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 [Q]Computer won't recognize phone? - Post #8. I had some slight differences on Windows 7.

For me I,

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

Good luck!

For what it's worth, in my case I was able to fix the problem simply by changing my USB connection mode from Media device (MTP) to Camera (PTP).

Answer 4

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:

1. Switch Windows into safe mode
2. Uninstall Android Composite ADB Interface
3. Install old SAMSUNG Android ADB Interface
4. Switch Windows into normal mode
5. Plug-in Android device (Nexus 4 in my case)
6. Windows recognized the device as Nexus 4
7. Install driver from android-sdk/extras/google folder
8. Everything works again! :)

Answer 5

I had the same problem, but I didn't want to change to PTP mode. This is how I fixed it with MTP still enabled.

1. Uninstalled Google USB Driver from Eclipse in the Android SDK Manager.
2. Uninstalled the driver from Device Manager - click box for "delete driver from my computer"
3. Unplugged and re-plugged my phone into the computer.
4. Windows "improperly" installed drivers for the Nexus 4.
5. The Nexus 4 was now showing up in My Computer like a drive.
6. Reinstall Google USB Driver in SDK Manager.
7. Update Nexus 4 driver in Device Manager.
8. Everything works.

Answer 6

On Windows 7, with Samsung Nexus S, it showed nothing in Device Manager, the adb devices command showed no devices, but when plugged in device said USB debugging was on and connected.

I used Andrea's Feb 2 answer to install the Google USB driver, which created the /gooogle/usb_driver directory and used RobertNovelo's Mar 7 answer to go to the link and follow the instructions. The device showed up in Device Manager under 'other'. I right clicked on it and selected update driver, and now it shows up in Device Manager under 'Android device', and now command line adb devices lists it.
