Hi,
I purchased two Yubikey 4. With a Yubikey (under Window 10), using the tool Yubikey Personalization Tool, I get the message: No Yubikey inserted. I also tried it on a second PC (always under Window 10) with the same result. :? The other Yubikey works perfectly.
What can be the problem? How can I fix it?

Thanks.

PS: This Yubikey initially was detected. I do not remember exactly what has been done but now is no longer seen. :roll:

EDIT: Under Linux (Debian 8) same problem. I have attached a file with "dmesg" output for the two keys.

The YubiKey Personalization Tool requires OTP mode to be enabled. Per dmesg you have disabled both U2F and OTP mode and put it in CCID mode only. The Personalization Tool is ONLY used to program the configuration slots (OTP), so it has to be enabled in order for the application to recognize the YubiKey. Use the YubiKey NEO Manager or YubiKey Manager to enable OTP mode.

Thank's. This solved the problem.
