Cannot connect to gpg smartcard with non-root user

Suddenly my gpg program cannot connect to the smartcard

 [tjm@ArchPad ~]$ gpg --card-status
gpg: selecting openpgp failed: No such device
gpg: OpenPGP card not available: No such device

However, pcsc_scan works

However it not works. So, does anyone who have ideas about this situation?

Re: Cannot connect to gpg smartcard with non-root user

It seems that the upgrade of gnupg today caused that issue:
[2017-01-27 19:50] [ALPM] upgraded gnupg (2.1.17-4 -> 2.1.18-1)

after downgrading gnupg again, it worked fine.

Thanks for your advice. I have tried downgrade the gnupg, but it's not work for me.

Re: Cannot connect to gpg smartcard with non-root user

I had this problem, I just fixed it like two seconds ago by adding

pcsc-driver /usr/lib/libpcsclite.so
card-timeout 5
disable-ccid

to .gnupg/scdaemon.conf and running "killall scdaemon"

Re: Cannot connect to gpg smartcard with non-root user

It works! Thank you. But do I need to kill scdaemon everytime after login?

Is this a legit fix? wont break anything to disable ccid?

Re: Cannot connect to gpg smartcard with non-root user

For me the fix was removing reader-port from scdaemon.conf

Re: Cannot connect to gpg smartcard with non-root user

TJM: no it is just to restart scdaemon, restarting your computer will do the same thing. its just the quicker way to check if it worked

rek2: I got it from the archwiki and it didn't break anything with the yubikey 4

Re: Cannot connect to gpg smartcard with non-root user

Works for me too, after creating the file .gnupg/scdaemon.conf

pcsc-driver /usr/lib/libpcsclite.so
card-timeout 5
disable-ccid

And to restart the daemon:

sudo systemctl restart pcsd

Re: Cannot connect to gpg smartcard with non-root user

Still seeing the errors in the pcscd journal but the card does work with the scdaemon.conf as above.
