OS X 10.6.6 and “adb devices” fails to list androi

Question

adb devices was working fine last year, but after upgrades and new software installs, adb devices no longer recognizes USB attached Android devices.

Here is what I have tried:

adb kill-server
adb devices

adb usb
  error: Device not found

Answer 1

Following the google bug submission... I set usb mode to Charge Only, and it detected the phone immediately. Pretty silly.

Answer 2

The last time I updated my tablet, it turned off "allow USB debugging", and I spent a half hour or so spinning my wheels. Double check that that is turned on in settings.

Answer 3

I have the same problem, I solved using an alternate install method.

First I put an sd card in my device. Then I use a File Manager to transfer the .apk to the device, and I install it from the device

You can see a tutorial in http://www.youtube.com/watch?v=7UOAw124y1s

Answer 4

For some devices running Android 4.4.2, you must enable tethering. You can do this in "Tethering and Mobile hotspot" and then check "USB tethering".

Answer 5

This thread is old but perhaps my answer will help somebody. Using a Motorola MB865 with OSX, ADB would recognize my phone only after I performed a factory reset.

I got the idea from this thread.

This was after I tried all the other tricks listed in other threads:

1. adb kill-server followed by adb start-server

2. Make sure USB Debugging is enabled

3. Make sure vendor USB ID listed in adb_usb.ini

4. Switching USB cables. For what it's worth, I did have to switch cables in order for the Mac to see the device. But this had no effect on ADB.

In the end, the factory reset did the trick.

Answer 6

Having just connected a brand new Motorola Atrix 2 to my Mac running 10.6.8, I had to pull down the menu from the top of the screen, tap on "USB Connection", and change it from "Motorola Phone Portal" to "Charge Only" before it would show up in my list of devices from adb. Hope this helps!
