I've been having a issue trying to get the adb devices command to pick up my LG TRANSPYRE™ (VS810PP) phone. Keep in mind the command does in fact work. So it's not an issue with adb, more with the drivers.

After taking a look from this post I found online, I did the steps properly (three times, just to be sure).

So I basically did this:

  1. Created a file: /etc/udev/rules.d/70-android.rules.
  2. Wrote SUBSYSTEM=="usb", ATTR{idVendor}=="1004", MODE="0666" to the file.
  3. Assigned proper permissions via sudo chmod a+rx /etc/udev/rules.d/70-android.rules
  4. Rebooted my computer.
  5. Restarted udev.

And the results:

$ adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached

(But nothing came after that)

But I didn't give up just yet. I read from another post here on Ask Ubuntu, I tried again.

Again, the process:

  1. Created a file: /etc/udev/rules.d/51-android.rules
  2. Wrote SUBSYSTEMS=="usb", ATTR{idProduct}=="1004", MODE="0666" to the file
  3. Gave proper permissions sudo chmod a+rx /etc/udev/rules.d/51-android.rules
  4. Rebooted the 'pooter.
  5. Restarted udev.

The output is the same as above, still not fixed...

I've very new to android, but my best guess is that I'm using some sort of out-dated method, because those posts are at either 2 or more years old. So there is probably a new method now.

Edit:

$ lsusb

  • Do you have USB debugging enabled on your phone? – s3lph Jun 05 '15 at 13:56
  • @the_Seppi Yes. –  Jun 05 '15 at 13:57
  • Mint isn't supported here. This is on topic on [unix.se] – Tim Jun 05 '15 at 14:03
  • Are any devices detected by the kernel when plugging the phone? Check the output of dmesg. Please note that Mint is off-topic here. You may want to ask on http://unix.stackexchange.com or rephrase your question so it fits for Ubuntu (but please check first whether this appears in an official Ubuntu system, an Ubuntu live system on USB should fit that.) – s3lph Jun 05 '15 at 14:03
  • @the_Seppi, when doing lsusb, I get Bus 005 Device 005: ID 1004:628a LG Electronics, Inc. as one of the entries. –  Jun 05 '15 at 14:09
  • Please use the [edit] function to add information to your question. What about dmesg? – s3lph Jun 05 '15 at 14:09
  • When doing dmesg, there is too much output for me to be able to identify anything (it output's so much in fact, it gets truncated by cutting off at the top.) –  Jun 05 '15 at 14:12
  • I tried greping the output. See the edit to the post. –  Jun 05 '15 at 14:14

Set mode from MTP to PTP. I had the same problem.

MTP means Media Transfer Protocol. PTP means Picture Transfer Protocol, which means that the phone appears to the computer as a digital camera.

To set the mode: Settings > Developer Options > scroll down to Select USB Configuration, tap this and select PTP or just click at notification in status bar and select PTP.

  • Perhaps this is a problem in themselves LG phones – OlegWock Jun 05 '15 at 14:44
  • Thanks! I've been struggling for quite some time until I found this answer – Warrior Jun 29 '16 at 18:11

    additionally do this : Go to Settings -> About phone -> Tap on "Build number" seven times. Voila !!! this enables Developer mode ... You will see new option called 'Developer Options' in the setting. From there I also had to enable USB debugging. Developer Options > USB Debugging ... adb kill-server ...
    adb start-server     – Scott Stensland Aug 12 '16 at 13:45

    What does this mean "set mode from MTP to PTP"? – Yanick Rochon Nov 18 '16 at 20:48
  • I had to allow adb and USB debugging explicitly on CM13. See comment from Scott Stensland how to enable – syss Nov 19 '16 at 13:30

    Selecting PTP did not change anything for me. Still no devices detected. Same for selecting Charge only, MIDI, Audio and all the other modes. – Sander Heinsalu Aug 14 '19 at 01:56

This happens to me sometimes with certain devices. Here's what I find works:

  1. Find the Vendor ID: You can do this by typing lsusb. My output is something like this:

    Bus 002 Device 097: ID abc1:1234 Fictional Company, Ltd.

    In this case, abc1 is the Vendor ID.

  2. Create an adb_usb.ini file: Run the following

    echo "0x<your device's Vendor ID>" > ~/.android/adb_usb.ini

  3. Restart adb

    adb kill-server
adb start-server

Since doing that, my devices have all shown up in adb devices.
