To access devices connected to USB via adb or fastboot on linux, you need to configure udev rules. For detailed information about udev, take a look at udev - Arch Linux from the ArchLinux wiki (note that UDEV rules are not exclusive to Arch; udev is used in numerous distributions).

Follow these steps to setup the correct rules:

  1. Verify your username is included in the plugdev group. Type
    groups
    from a terminal and look for plugdev in the listed groups. If you do not see plugdev listed, you can add your username to the group with:
    sudo gpasswd -a username plugdev
    where username should be replaced with your linux username.
  2. Copy the set of rules listed below these steps to a text file and save it as /etc/udev/rules.d/51-android.rules. You will need sudo/su to write to that directory. So, for instance:
    sudo nano /etc/udev/rules.d/51-android.rules
    These rules cover all vendors listed by Google. Optionally, you can add just the vendor corresponding to the device(s) you plan to connect to your computer.
  3. Restart your computer and then test plugging in your device to the computer with USB debugging enabled.

Troubleshooting

1. Make sure your device is connected and accessible via usb. lsusb should show a list of connected devices. The section after 'ID' in the output should match one of the idVendor numbers from the udev rules. For example, a Nexus One with idVendor 18d1 should return something like:

Bus 001 Device 005: ID 17ef:480d Lenovo Integrated Webcam [R5U877]
Bus 002 Device 002: ID 0bda:0119 Realtek Semiconductor Corp. 
Bus 002 Device 009: ID 18d1:4e12 Google Inc. Nexus One (debug)
Bus 004 Device 003: ID 0a5c:2145 Broadcom Corp. Bluetooth with Enhanced Data Rate II
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

2. If the device is detected in lsusb, try running adb devices. If you get ???????????? device, try reloading the udev rules:

 sudo sh -c "(udevadm control --reload-rules && udevadm trigger --action=change)"

You can also try disconnecting and reconnecting the usb cable to your device.

3. If you cannot access your device via adb, even after adding your linux user to the plugdev group and restarting the computer, you can try starting the adb service as root. This is dangerous and not recommended:

adb kill-server
sudo $(which adb) start-server
adb devices

Similarly, if fastboot devices returns no permissions, try running fastboot as root:

sudo $(which fastboot) devices
