Список устройств adb в Ubuntu 16.04 пуст

У меня такая же проблема, как что (я пытаюсь объяснить это, чтобы помочь ему, но у меня это не работает) с Nokia 6.1 (на android 8.1), при запуске устройств adb список устройств пуст, я делаю это:

sudo apt install android-tools-adb android-tools-fastboot

adb version ==> Android Debug Bridge version 1.0.32

cd /etc/udev/rules.d/

sudo nano 51-android.rules 

sudo chmod a+r 51-android.rules 

sudo groupadd adbusers

sudo usermod -a -G adbusers $(whoami)

sudo udevadm control --reload-rules

sudo service udev restart

adb kill-server

adb devices

Мой 51-android.rules:

# These rules refer: https://developer.android.com/studio/run/device.html
# and include many suggestions from Arch Linux, GitHub and other Communities.
# Latest version can be found at: https://github.com/M0Rf30/android-udev-rules

# Skip this section below if this device is not connected by USB
SUBSYSTEM! = "usb", GOTO = "android_usb_rules_end"

LABEL = "android_usb_rules_begin"
# Devices listed here in android_usb_rules_{begin...end} are connected by USB

# Nokia 6
ATTR{idVendor}= = "2e04", ENV{adb_user} = "yes"

# Symlink shortcuts to reduce code in tests above
ENV{adb_adbfast}= = "yes", ENV{adb_adb} = "yes", ENV{adb_fast} = "yes"
ENV{adb_adb}= = "yes", ENV{adb_user} = "yes", SYMLINK+ = "android_adb"
ENV{adb_fast}= = "yes", ENV{adb_user} = "yes", SYMLINK+ = "android_fastboot"

Anyone have an idea, what is the problem ? (because I looking for on different forum and I don't know why my list of device is empty)
