I just got a new Yubikey NEO-n and was trying to configure it for U2F+CCID mode using ykpersonalize. Nothing seemed to work with the U2F demo (I never got it working at all). I couldn't use the Yubikey NEO Manager because it won't even install on OS X Yosemite.
I tried a few different settings, and after awhile ykpersonalize reported it could no longer see the Yubikey at all. I did not physically remove it during this process:
Code:
$ ykpersonalize -m6

Yubikey core error: no yubikey present
All I see reported now is "Yubikey core error: no yubikey present". When I insert the Yubikey, it blinks briefly then shuts off. It blinks periodically (once every 4 seconds or so). Touching the button does nothing.Statistics: Posted by bascule — Sat Oct 25, 2014 6:51 am
