mac os x 10.6.6 and "adb devices” fails to list android devices

" ADB devices" was working fine last year, but after upgrades and new software installs, adb devices is no longer recognizes any usb attached android devices. I wonder whether you can suggest how to fix this problem. Thanks,

Here is what I did:

adb kill-server
adb devices

adb usb
error: Device not found

  1. If you have installed EasyTether on OS X, the EasyTetherUSBEthernet.kext can prevent adb from communicating with your mobile device.

    If you use Easy Tether, BEFORE you plug in your phone run:

    sudo kextunload /System/Library/Extensions/EasyTetherUSBEthernet.kext

    (or unplug/plug your phone in after)

    If you are done debugging and want to use EasyTether again, either restart or:

    sudo kextload /System/Library/Extensions/EasyTetherUSBEthernet.kext

    If you want to remove the EasyTether kext so it never hassels you again:

    sudo kextunload /System/Library/Extensions/EasyTetherUSBEthernet.kext
    sudo rm -rf /System/Library/Extensions/EasyTetherUSBEthernet.kext

  2. After connecting the device and enabling the USB debugging please go to the path of adb, which is now inside the android-sdk-->platform-tools and type the following command ./adb devices. I think this will list the devices connected.

  3. I have seen another report of this bug. I have not been able to reproduce it myself yet.

    The bug is:
    MacOS X 10.6.6 [on some hardware] breaks adb [for some phones].

    If anyone is able to reproduce the bug, feel free to add details of the exact hardware, build numbers and so on. I've asked the person who can reproduce the bug, to report it to google using the form at http://code.google.com/p/android/issues/entry

    When he does that, I will add the bug report URL here, and people can add their hw/sw details to the bug report.

    In the meantime, to be safe, I would recommend Apple users should NOT accept the snow leopard upgrade to 10.6.6, which was pushed on Jan 6 2011 (so it may already be too late for most).


  4. The bug report to Google is

    If you have encountered this bug (upgrade to MacOS 10.6.6 and adb no longer sees some phones on USB) please add a comment with any useful relevant info (like your exact hardware type).

  5. I was having the same issue and tried connecting as charge only, but that didn't solve the problem, then unchecked the "Unknown sources" option to allow installation of non-market applications, tried it again and it recognized the device. I'm running android 2.2.3.

  6. 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

  7. I too am having this problem. However, it isn't just a problem with ADB, it's a problem with android devices in general on Mac OSX 10.6.6 Snow Leopard. Devices that used to work in 10.6.4 will no longer even mount the device as a USB drive. Googling to see if I can find the answers.

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

  9. I just ran into this problem using my HTC Inspire (Android 2.3.3) and Mac OS 10.6.8.  The phone did not enter USB debugging mode when I connected it to my USB hub, but it did start USB debugging mode when I connected it directly to my MacBook Pro.

    ... and then, of course, it showed up in the list of devices attached.

  10. The EasyTether fix worked for me, although first I had to load the kext file, then unload it. My Droidx popped up right away!

    By the way, I'm running Snow Leopard 10.6.8 on my MacBookPro, so those who are having trouble with adb and connecting devices should check any USB applications, like EasyTether, for conflicts. Also be sure to follow all the above rules for
    1. Application debugging (Settings->Applications->Development)
    USB debugging: ON
    2. USB connection (on notification bar).
    Choose USB Mass Storage (altho Charge Only also works with my droidx and MacBookPro)
    3. Unknown Sources (Settings->Applications->Unknown Sources = ON)

  11. 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!

  12. I had this problem today with my HTC mytouch phone and OS 10.6.8. At the same time, the phone reported a damaged SD card. The solution was to remove the Micro SD card and erase/format it using disk utility as FAT 32. The name I gave the SD card volume appeared in the Finder when I tried connecting again (charge only). For some reason, Android reported the card as damaged but could not format it. I used a Micro SD USB adapter. My Macbook didn't see the card until I carefully slid it out and back into the adapter slot. This is a known problem with HTC android phones.
