fix adb devices no permission

Error:

$ adb devices
List of devices attached
52003c2b58b445db	no permissions (user in plugdev group; are your udev rules wrong?); see [http://developer.android.com/tools/device.html]

Fix: 
1> sudo usermod -aG plugdev $LOGNAME (https://developer.android.com/studio/run/device)
2> lsusb
3> sudo vi /etc/udev/rules.d/51-android.rules
4> SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", ATTR{idProduct}=="2e81", MODE="0666", GROUP="plugdev" (idVendor, idProduct found at lsusb command)
5> sudo udevadm control --reload-rules
6> sudo adb kill-server
7> sudo adb start-server

I always have this problem when my Pixel is in "Charging Only"/"No data transfer" mode. Setting it to "File transfer" (others may work as well) is the fix in this case. (Just leaving this info here for the next time I end up here from Google wink )

Much appreciated Sir, found it difficult to understand why the error occurred in the first place but this helped fix it anyway, immensely helpful...
