## Determine your device id

1. Unplug your device from the computer and type `lsusb` in the terminal. You should get an output similar to this:
  ```bash
  Bus 002 Device 002: ID 8087:8000 Intel Corp. 
  Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  Bus 001 Device 002: ID 8087:8008 Intel Corp. 
  Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
  Bus 003 Device 005: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
  Bus 003 Device 033: ID 0cf3:3004 Atheros Communications, Inc. AR3012 Bluetooth 4.0
  Bus 003 Device 047: ID 045e:07fd Microsoft Corp. Nano Transceiver 1.1
  Bus 003 Device 002: ID 174f:148d Syntek 
  Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  ```

2. Now plug your phone into the computer and run the command again, the output should be different:
  ```bash
  Bus 002 Device 002: ID 8087:8000 Intel Corp. 
  Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  Bus 001 Device 002: ID 8087:8008 Intel Corp. 
  Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
  Bus 003 Device 005: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
  Bus 003 Device 033: ID 0cf3:3004 Atheros Communications, Inc. AR3012 Bluetooth 4.0
  Bus 003 Device 047: ID 045e:07fd Microsoft Corp. Nano Transceiver 1.1
  Bus 003 Device 002: ID 174f:148d Syntek 
  Bus 003 Device 060: ID 05c6:6765 Qualcomm, Inc. 
  Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  ```

3. Take a note of the new output ID. For me it's `Bus 003 Device 060: ID 05c6:6765 Qualcomm, Inc.`

4. The value we are interested in is the first one before the colon (:); in this case `05c6`. 
  You can check that the value you get is the same as the ones listed [here](https://devicehunt.com/all-usb-vendors)

### Note
_On [Arch Linux](https://www.archlinux.org/), it might be enough to install [android-udev](https://www.archlinux.org/packages/community/any/android-udev/) package, so you can skip the below steps. See [ArchWiki#Adding udev rules](https://wiki.archlinux.org/index.php/Android_Debug_Bridge#Adding_udev_rules)_

## Some code
1. Use your favourite text editor to edit the file: `/etc/udev/rules.d/51-android.rules`

2. In the new file, enter the following:
  ```udev
  # Phone name
  SUBSYSTEM=="usb", ATTR{idVendor}=="id_you_copied", MODE="0666", GROUP="plugdev"
  ```
3. Make sure to replace `id_you_copied` with the one we determined from the previous section

4. Save and close the file.

5. Now in the terminal, run the following commands
 ```console
 sudo chmod a+r /etc/udev/rules.d/51-android.rules
 sudo systemctl restart udev
 ```
 The first command is to make the file we created readable by all users (should be unless you've set a umask of 0027 or 0077) and the second command restarts the udev (usb device) manager, via systemd.
 
6. Now you can try the command `fastboot -l devices` and it should successfully list your device as one of the entries
