Fix connection issues

In some cases users may encounter connection issues when trying to connect their Ledger Nano S or Ledger Blue device. Different solutions are available, depending on your operating system. Please select your system below.

Windows

Please try with another USB cable. If possible, please try on a Mac computer to verify that your Ledger Nano S is not faulty.

Linux

Add udev rules

Create a set of udev rules to allow device access. Refer to the Chrome USB API documentation for details. Use the following command and retry to access the application.

wget -q -O - https://raw.githubusercontent.com/LedgerHQ/udev-rules/master/add_udev_rules.sh | sudo bash

If needed, add user to plugdev group

Modify the above /etc/udev/rules.d/20-hw1.rules rule to match your group or add the OWNER="username" parameter to each line, where username is your Linux user name. This adds your user to the plugdev group. Retry once you've done this.

For Arch Linux, the following rules are used:

/etc/udev/rules.d/20-hw1.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2581", ATTRS{idProduct}=="1b7c", MODE="0660", TAG+="uaccess", TAG+="udev-acl"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2581", ATTRS{idProduct}=="2b7c", MODE="0660", TAG+="uaccess", TAG+="udev-acl"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2581", ATTRS{idProduct}=="3b7c", MODE="0660", TAG+="uaccess", TAG+="udev-acl"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2581", ATTRS{idProduct}=="4b7c", MODE="0660", TAG+="uaccess", TAG+="udev-acl"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2581", ATTRS{idProduct}=="1807", MODE="0660", TAG+="uaccess", TAG+="udev-acl"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2581", ATTRS{idProduct}=="1808", MODE="0660", TAG+="uaccess", TAG+="udev-acl"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2c97", ATTRS{idProduct}=="0000", MODE="0660", TAG+="uaccess", TAG+="udev-acl"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2c97", ATTRS{idProduct}=="0001", MODE="0660", TAG+="uaccess", TAG+="udev-acl”

Still not working?

If this still doesn't work you may need to add these rules:

KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0660", GROUP="plugdev", ATTRS{idVendor}=="2c97"
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0660", GROUP="plugdev", ATTRS{idVendor}=="2581"
