ADB is not detecting my android device on Ubuntu

问题

Need help, "adb" not detect my phone, I do not know what to do; and this was what I did, if I have a mistake or something tell me please.

1. I log in as root and create this file.

   /etc/udev/rules.d/51-android.rules
   

2. These are my rules, for my phone LG L80+Bello D331.

   SUBSYSTEM=="usb", ATTRS{idVendor}=="1004", MODE="0666"
   

3. I run this command and reboot.

   chmod a+r /etc/udev/rules.d/51-android.rules
   

4. Finally, I test my changes, but don't display my devices.

   $ adb devices
   List of devices attached

$ adb devices

Update 2

Here is the solution

回答1:

from lsusb output I see that your device connected to Bus 004 as a device 005

Here it is Bus 004 Device 005: ID 1004:6300 LG Electronics, Inc.

I see that you did not create any group.You need to create a group (if permission denied prepend "sudo" following commands):

1) add plugdev group:

 groupadd plugdev

2) add your username to plugdev group (useradd -G {group-name} username):

 useradd -G plugdev orvi

3) restart udev (you may need to log off and log back in to update user group):

 sudo service udev restart

4) Now reload the rules with the following commands:

 sudo udevadm control --reload-rules
 sudo service udev restart
 sudo udevadm trigger

5) Verify device is now allowing plugdev user group access

ls -l /dev/bus/usb/<bus number from step 4>

It should give something like that:

  crw-rw-rw- 1 root plugdev 189, 329 Jul  3 18:23 074

6) Run adb devices to confirm permissions are correct and enjoy!

回答2:

I know your issue was solved, but for everyone in the future make sure you don't have two versions of adb running. Android Studio comes with adb and I installed adb through yum. The instances were interfering with each other and caused lots of issues including not being able to see my device.

回答3:

My phone thought it was connected to the computer, but the computer wouldn't recognize it. On my phone I tapped the notification for 'USB Debugging Enabled', scrolled to 'USB Debugging', and toggled the setting off and on again. adb then saw my phone.

回答4:

On Ubuntu 16.04, I had to install the latest android sdk, rather than the one that comes with apt-get, and finally I could see the devices from adb.

回答5:

Use apt-get install to install the android-tools-adb package.

This gives you a community-maintained default set of udev rules for all Android devices.

Make sure that you are in the plugdev group. If you see the following error message, adb did not find you in the plugdev group:

error: insufficient permissions for device: udev requires plugdev group membership

Use id to see what groups you are in.

Use sudo usermod -aG plugdev $LOGNAME to add yourself to the plugdev group.

The following example shows how to install the Android adb tools package. apt-get install android-tools-adb
