Enabling Yubico U2F Security Key on Chrome for Ubuntu 15.04

This works for the blue FIDO U2F key.

Create a new file called /etc/udev/rules.d/50-security-key.rules:

**SUBSYSTEMS=="usb", ATTRS{idVendor}=="1050", OWNER="root", GROUP="plugdev", MODE:="0660"**

Once that file is saved, sudo udevadm control -reload-rules and then restart Chrome. Your security key, which previously was likely giving you a “An unexpected error occurred [retry]” message, will now work.

I figured this out with the command udevadm info -n /dev/usb/hiddev0 -a, inspecting the output to determine that other solutions on the web were missing the S at the end of SUBSYSTEMS and ATTRS. For the assignment parts of the udev rule, the values root/plugdev/0660 were correct.

Same idea for the Feitian ePass NFC FIDO U2F Security Key, except idVendor is 096e.
