It fails to find a device because you don't have a configuration. As I explained in: https://bugs.debian.org/854616 Until we fixed configuration (by adding an entry for Yubikey), please have a udev rules like: ---------------- /etc/udev/rules.d/yubikey-neo-u2f-ccid.rules ATTRS{idVendor}=="1050", ATTRS{idProduct}=="0115", MODE="664", GROUP="plugdev" ---------------- And please add yourself as a group member of "plugdev". In my case, I have this line in /etc/group: plugdev:x:46:gniibe The idProduct value is my guess. Please confirm by lsusb command. In my case: $ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 009: ID 234b:0000 Bus 001 Device 008: ID 234b:0000 Bus 001 Device 007: ID 05e3:0608 Genesys Logic, Inc. Hub Bus 001 Device 003: ID 0489:e056 Foxconn / Hon Hai Bus 001 Device 002: ID 1bcf:2c67 Sunplus Innovation Technology Inc. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub 234b:0000 (idVendor = 234b, idProduct=0000) is my Gnuk Tokens. And please reply back to us again, so that we can add a correct entry for the configuration. --
