Cannot connect Nexus One Phone to Android adb

Asked 13/11, 2010 at 22:8 Answered 18/6, 2012 at 9:12

I am running Android SDK 2.2 and am trying to get the adb to connect to the Google Nexus One phone. Its a new phone, shipped straight from Google - haven't installed any apps on it yet. (I have Windows XP) Here is what I have done so far:

Followed the instructions on setting up the device for development as given on the Android Developer's site: http://developer.android.com/guide/developing/device.html
added android:debuggable="true" to my application manifest
USB debuggable is checked on the phone
downloaded the Device Drivers For Windows Revision 3 (this supports Nexus One phones)
Went through the Hardware Installation wizard to install the device - the device shows up as "Android Composite ADB Interface".

When I run adb devices on the shell, the device appears for a moment, then disappears. On the Eclipse console, I get the following message: [2010-11-13 11:54:42 - DeviceMonitor]Failed to start monitoring

I have rebooted the pc several times, uninstalled and reinstalled the drivers several times, but I get the same error each time. As I was researching this problem, someone had recommended rebooting the phone. I am a bit confused by that - is that a soft or hard reboot? Do I just power the phone off/on and is there something more complex involved? Do I have to hard reboot it to reset to factory version - even though its brand new?

Has anyone run into a similar problem? Any help on this would be great. I can't test my application on the device if the adb cannot view the device. Thanks so much in advance.

"Do I just power the phone off/on and is there something more complex involved?" -- if somebody tells you to reboot your phone, a simple power-off/power-on (note: not just putting the phone to sleep) will suffice. – Muscovado 13/11, 2010 at 22:10

I had very similar problem with Nexus one (although happened with other devices too). For some reason it didn't work when I used a keyboard USB hub to connect to the device but started to work correctly when I started to connect the USB cable to directly yo my laptop. It could also be a faulty USB cable. I have one (cheap) cable that works for recharging but does not work for debugging. Worth checking the cable. – Strychnine 14/11, 2010 at 15:5

I had this same problem. To get it working, do the following:

Close Eclipse
Open Task Manager and kill the adb.exe program.
Re-open Eclipse (Eclipse will automatically restart the adb.exe service)

Run adb devices from a command prompt and you should see something like the following:

C:\> adb devices
List of devices attached
0123456789ABCDEF        device

Of course, I'm assuming you have your phone plugged into your computer.

I also restarted my tablet, and it solved this problem for me. Thanks – Eolanda 13/6, 2012 at 13:30

Unless adb really isn't responding, you can also just execute adb kill-server. – Lowland 10/3, 2013 at 14:58

It sounds like something is killing the service as soon as it starts. Try disabling any anti-virus and running adb devices again. You can also check your system logs for errors - run compmgmt.msc and check the Event Viewer's logs.

When I run adb devices on the shell, the device appears for a moment, then disappears

Do you mean Windows' command shell cmd.exe? The output of 'adb devices' doesn't update itself, it should just print out what's currently connected then terminate.

I tried the above suggestions - ran compmgmt.msc - nothing shows up in the Event Viewer Logs. Also tried rebooting the phone (powered it off and on). Still the same error message in the Eclipse console - adb still doesn't see the device. – Guanajuato 14/11, 2010 at 8:54

Nothing here worked for me. And you know what? I plugged it to my USB 3.0 port.

Just plug it to regular USB 2.0 and it'll work.

Changing which USB port it was plugged into worked for me. However I don't think it was because it was plugged into a USB 3.0 port. – Fertilizer 12/5, 2012 at 18:40

I'm not the only person who reported it. I don't know what is the exact reason, but searching for the solution I found several developers having problem with usb 3. Some people have problems with their cables also, so the reasons may be mixed – Anyaanyah 12/5, 2012 at 20:29

I had a similar problem, running Linux Mint Debian Edition. Using one particular USB port, I cannot connect to the phone, adb gives the serial number as ???????????? and says no permissions. With other ports it works. All my ports are USB 2. – Libove 9/7, 2013 at 18:34

Hi you jst need upgrade your usb driver, follow this ref link, after upgrading you need to uncheck USB debugging, disconnect cable from device and then check USB debugging and connect cable to device again. this'll solve your problem.. link text

I had this same problem. Do the following:

Plug your phone into your computer and:

Run the command prompt.

Go to the tools location of the android sdk.

run 'adb kill-server'

then run 'adb start-server'.

Turn off COMODO Firewall and Defense+ module

I got my Nexus One on Windows 7 64 bit going by following these instructions:

http://developer.android.com/sdk/win-usb.html

Note that the directory has changed to /extras/google/usb_driver.

You know that you need to do this if you go to control panel->devices and printers and show properties on the device, and there's no driver shown.

Open the task manager by Ctrl+Shift+Esc
In the Processes select adb.exe and Click the End process Button.
Now close the eclipse and restart it again.

This worked for me. Hope this would work for you as well.
