Yubico Security Keys

[Robert Ames]

I just upgraded to 11.2-RELEASE with Firefox 60.0.1_1,1 from packages.
It's my understanding Yubico Security Keys should be supported (I
have one of the blue ones).  In Firefox I did about:config and set
security.webauth.u2f to true.  When I go to https://demo.yubico.com/u2f
to test it, the "Register a U2F device" fails with:


Registration failed!
Make sure you have a U2F device connected, and try again.
 Traceback (most recent call last):
  File "/root/python-u2flib-server-demo/examples/yubiauth_server.py", line 161, in __call__
    raise Exception("FIDO Client error: %s" % error)
Exception: FIDO Client error: 4 (DEVICE INELIGIBLE)


FreeBSD sees the device:

Sep  4 17:25:13 freebsd kernel: ugen1.4: <Yubico Security Key by Yubico> at usbus1
Sep  4 17:25:13 freebsd kernel: uhid0 on uhub4
Sep  4 17:25:13 freebsd kernel: uhid0: <Yubico Security Key by Yubico, class 0/0, rev 2.00/5.02, addr 4> on usbus1

So should this just work out of the box or is there something I'm
missing?
