Hi,

I just had the same problem with a build-in smartcard reader. The approach of Klas was right.
But you have to add this line to your scdaemon.conf:

Code:

reader-port Yubico Yubikey NEO OTP+CCID 0

That's the name scdaemon recognizes the Yubikey with the corresponding Port "0".

I followed these steps and I am still unable to get gpg to read the card. The only difference that I know of is that mine has connection modes OTP+U2F+CCID so I made that change in the scdaemon.conf and still was not able to get it to work.

So for a moment it was able to read the card after writing my last message but it could not write new information to the card. When I went through the steps earlier I was unable to read the card again. Also I have another smartcard client installed and running. Would that also give the scdaemon problems?

That's a solution i was looking for YEARS!
I suppose it's worth to be added to Yubikey FAQ , really!

I think it's just exporting a stub that says "go look for the smartcard with this serial number" so that you can reference it on other computers. Note that all YubiKey NEOs present a serial number of 000000000001, so beware of relying on that.

This is what gpg --export-secret-key does, anyway.

Thanks Klas,

I had to physically remove the other reader and reboot, but it's working now.

After you've disabled the other card reader:
* unplug the neo
* kill the processes scdaemon and gpg-agent
* replug the neo

That works for me on a windows 7 machine with another card reader.

I'm also getting:

gpg: selecting openpgp failed: Card error
gpg: OpenPGP card not available: Card error

I'm in mode 82 and my device manager looks like attached.

I'm Windows 8 x64.

My Neo version is 3.1.0.

I do have another card reader which you can see I've disabled.

Cheers

Unfortunately I get much the same results. It seems difficult to specify the reader to use under windows, your best bet is probably disabling the other smartcard readers from the device manager. Having done that the YubiKey NEO should be the only smartcard reader in the system and thus the one selected.

Klas,

It didn´t work. I am still receiving this message:

gpg:Selecting openpgp failed: Card error

gpg:openPGP card not available : card error.

Any new idea?

tks

Very good, now let's solve this..

On your screenshot it looks like your computer thinks it has several smart card readers, that' probably why it gets confused, so I want you to:

* Create a file called scdaemon.conf in your gnupg home directory (for me that is at c:\Users\UserName\AppData\Roaming\gnupg\) the directory should already exist.
* Add the line: reader-port Yubikey Neo OTP+CCID
* Make sure there is no process running namned scdaemon
* Run gpg --card-status

Could of course be a bug there, but in that case one we haven't found and fixed yet..

So.. Would you mind posting (or mail to me at klas@yubico.com if you don't want it public) a screenshot of the relevant part of your device manager.. A screenshot of what it looks like for me when working in gpg is attached.

I manage to get this error when running a virtual windows on a linux host (VirtualBox) and the host has pcscd running.
