Bus 001 Device 008: ID 058f:6366 Alcor Micro Corp. Android Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Find the corresponding line for your android phone.
The Vendor & Product ID will be in XXXX:XXXX format. In our example the ID's is 058f:6366 .
058f = VendorID.
6366 = ProductID.
Create Rules.

sudo gedit /etc/udev/rules.d/51-android.rules
you can use vi, nano, pico or any text editor in place of gedit.

append the code to the file.
SUBSYSTEM=="usb", ATTR{idVendor}=="058f", ATTR{idProduct}=="6366", MODE="0666", GROUP="plugdev"
Create adb file in home ( ~ ) folder.

mkdir ~/.android
( if not already created. )

touch ~/.android/adb_usb.ini

echo '0x6366' >> ~/.android/adb_usb.ini
Restart udev.

sudo service udev restart

adb kill-server

adb start-server
Reconnect the Phone.
You may need to disconnect and reconnect the phone again. and wait for a couple of minute to get it detected.
adb devices

List of devices attached 19761202 device 45024745 device

# The short way.

Copy this code into the terminal (replaces id's) and run it.


echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="6366", ATTR{idProduct}=="058f", MODE="0666", GROUP="plugdev"' | sudo tee -a /etc/udev/rules.d/51-android.rules && mkdir ~/.android/ && touch ~/.android/adb_usb.ini && echo '0x6366' >> ~/.android/adb_usb.ini && sudo service udev restart && adb kill-server && adb start-server && adb devices

Replace the VendorID & ProductID with the one you got....
