Setup Leger Nano S on Ubuntu Linux

This is a quick HOW-TO for getting your new Ledger Nano S running in Ubuntu

Install

1. Choose a PIN on your Nano S
2. Record the 24-word seed on the supplied papers
3. Create a new udev rule so that ubuntu will recognize the USB device.

    sudo subl /etc/udev/rules.d/ledger.rules
   

4. Paste the following into the udev rules file. Be sure to replace your username:

    SUBSYSTEMS=="usb", ATTRS{idVendor}=="2c97", ATTRS{idProduct}=="0000", MODE="0660", TAG+="uaccess", TAG+="udev-acl" OWNER="<UNIX username>"
    SUBSYSTEMS=="usb", ATTRS{idVendor}=="2c97", ATTRS{idProduct}=="0001", MODE="0660", TAG+="uaccess", TAG+="udev-acl" OWNER="<UNIX username>"
   

5. Reload the rules. udevadm control --reload-rules && udevadm trigger. Optionally just unplug and replug your Nano S.
6. Your Nano S should now present you with its public key on its screen. See the usb listing:

    lsusb -d 2c97:0001 -v
   

Verify Authenticity
